Модульно-параметричний принцип розробки проектів шестеренних гідравлічних машин

The conventional system of design development of gear-type hydraulic machines and their implementation is not sufficiently perfect for a number of reasons. This system cannot be effective in the conditions of large-scale production. The purpose of the work is to create such a principle of designing a model range of gear hydraulic machines, which optimizes the conditions of production and marketing, with the subsequent reduction of the cost of production. To achieve the goal, the theory of "redundant connections" was used, and the design scheme of the hydraulic machine was analyzed. On the results of the conducted analysis, several possible schemes for the extraction of "redundant connections" were developed, and the calculation was carried out. From the proposed schemes, the most appropriate scheme for creating a gear-type hydraulic machine was determined - a scheme using the central load of the driving gear and a barrel-shaped profile of the longitudinal contour of the tooth of the driven gear. The paper also considers additional benefits arising from the removal of redundant connections. On the basis of the developed diagram of the action of forces in gear engagement, it is shown how deviations from the geometric accuracy of the gear affect the operation of the hydraulic machine and why the proposed scheme with a barrel-shaped profile of the longitudinal contour of the tooth is more appropriate. Among the important results of the research should be attributed the synthesized perspective scheme of design of a gear hydraulic machine. The use of the proposed scheme will allow the reduction of redundant connections (from 7 to 5, relative to the conventional scheme), which will contribute to the reduction of additional deformations and energy losses when working in the hydraulic motor mode and fluid losses when working in the hydraulic pump mode. And the implementation of one of the coupled gears with a barrel-shaped longitudinal profile of the teeth will ensure the stabilization of the displacement moment when the unit is operating in the hydraulic motor mode and will stabilize the hydraulic efficiency parameter when operating in the pump mode.

A fuzzy set theory-based fast fault diagnosis approach for rotators of induction motors.

Induction motors have been widely used in industry, agriculture, transportation, national defense engineering, etc. Defects of the motors will not only cause the abnormal operation of production equipment but also cause the motor to run in a state of low energy efficiency before evolving into a fault shutdown. The former may lead to the suspension of the production process, while the latter may lead to additional energy loss. This paper studies a fuzzy rule-based expert system for this purpose and focuses on the analysis of many knowledge representation methods and reasoning techniques. The rotator fault of induction motors is analyzed and diagnosed by using this knowledge, and the diagnosis result is displayed. The simulation model can effectively simulate the broken rotator fault by changing the resistance value of the equivalent rotor winding. And the influence of the broken rotor bar fault on the motors is described, which provides a basis for the fault characteristics analysis. The simulation results show that the proposed method can realize fast fault diagnosis for rotators of induction motors.

Change in power and fuel consumption when engine cylinders are partially disabled in a wheeled vehicle

The provided calculation methodology enables the evaluation of how disconnected cylinders affect engine power, overall efficiency, and fuel consumption. The study establishes that disconnecting cylinders leads to a proportional decrease in engine power. This means that an engine generating 154,5 kW power reduces to 113,4 kW with two disabled cylinders and goes down to 70,3 kW when four cylinders are disconnected. Reducing fuel consumption is especially notable at idle, showing a 27% drop after disabling half of the cylinders. However, fuel efficiency declines as the engine load increases until it reaches zero at the engine load factor. Discrepancies between the experimental and calculated data on fuel consumption and power are minimal, at around 7-8% during maximum load. Diesel engines have the potential to improve efficiency by shutting down certain cylinders, but the actual fuel savings depend on several factors, including the number of active cylinders, engine configuration, load, and mechanical losses incurred by the shutdown cylinders. A method for analyzing additional energy losses in the engine caused by forced and natural vibrations of motor-transmission systems in wheeled vehicles has been improved. The analysis utilizes the Meander function in the context of harmonic moment and Fourier series. This text describes a method for determining the power of mechanical losses and energy for pumping strokes, while considering changes in the temperature regime in disconnected engine cylinders at increased torque irregularity. It also determines the permissible number of disconnected cylinders, taking into account their effect on power and reliability of wheeled machines. This paper presents a method for evaluating the dependability of fundamental engine components in the context of increased torque irregularity resulting from the disconnection of some cylinders.

Development of an untraditional technique to control the structure of the output flow from a vortex chamber

A technique of using coherent vortex formations of the dead-end zone of the vortex chamber of the end type as a controlling factor influencing the structure and characteristics of the output flow has been developed. The kinematic parameters of the flow relative to chambers with elongated and extremely short dead-end parts in the range of Reynolds numbers according to the parameters of the nozzle Re=47080–86530 were investigated. The reaction of the flow structure in the output sections of the vortex chambers was determined experimentally using thermoanemometry. Profiles of time-averaged transversal and axial velocity projections, as well as corresponding values of the relative intensity of velocity pulsations, were obtained. It was found that at Re=86530, the elongation of the dead-end part of the chamber leads to a decrease in the initial cross-section of the transversal component by 15 % with an increase in the axial component by 19.7 %, and, at Re=47080, to a decrease in the transversal component by 21 % with an increase in the axial component by 8.5 %. This indicates the redistribution of kinetic energy from transversal to axial energy motion, which is confirmed by the analysis of the corresponding intensity profiles of the velocity pulsations in the output section of the chamber in the near-wall and near-axis zones of the flow. The integral intensity of the velocity pulsations along the initial cross-section of comparable chamber designs increases in a chamber with an elongated dead-end part with almost no additional energy losses. The obtained results form the basis of a rational method of controlling the macro- and microstructure of flows, which determines the efficiency of mass exchange and heat exchange processes in vortex chambers of the end type. Such designs are characteristic of vortex mixers, burners of industrial furnaces, furnace devices of hot water and steam boilers, and other technological and power equipment

МНОЖЕСТВЕННЫЙ ДОСТУП В БЕСПРОВОДНЫХ КАНАЛАХ С ИСПОЛЬЗОВАНИЕМ НЕОРТОГОНАЛЬНОГО КОДИРОВАНИЯ И ЧАСТОТНОГО ПЕРЕМЕЖЕНИЯ

Code division multiple access (CDMA) is currently considered as one of the promising technologies that can significantly improve the efficiency of modern and future communication networks. In code division multiple access systems, users can share a dedicated space-frequency-time resource to simultaneously transmit their own traffic. To ensure the separation of individual user streams on the receiving side, each user is provided with his own code sequence embedded in the broadband signal transmitted by this user, the spectrum of which, as a rule, occupies the entire allocated frequency band. When centimeter-and- millimeter wave wireless channels are used as the transmission medium, such factors as fading, multipath, and Doppler scatter can significantly degrade the performance of a code division multiple access system. The standard solution in this situation is to combine code division multiple access with OFDM (orthogonal frequency division multiplexing) technology, known as multicarrier CDMA (MC-CDMA). To ensure the acceptable level of performance of multiple access systems under oversaturated conditions, many novel approaches based on the use of non-orthogonal multiple access (NOMA) have been proposed. The paper considers a variant of multiple access with non-orthogonal coding that is close in approach to sparse coding multiple access (SCMA). The proposed access procedure is based on dividing the allocated time-frequency resource into relatively small clusters and sharing each cluster with its own group of users, equipped with a non-orthogonal cluster code with the ability to change the loading factor. For the proposed class of cluster codes, a general encoding and decoding scheme is presented. Examples of specific cluster code constructions and numerical results are given that allow one to get a number of the parameters for tradeoffs between an increase of the loading factor in the system and additional energy loss.

Active Thermal Control for Buck Converter-Based Active Power Decoupling Circuit

Aluminum electrolytic capacitors (AECs) and power semiconductor devices (PSDs) are typically identified as weak links in the reliable design of power converters. To eliminate the AECs from the design, active power decoupling (APD) circuits are preferred in single-phase power converters. However, in an attempt to eliminate AECs, this approach introduces the latter weak link in the design, i.e., PSDs in the APD circuit. This article proposes an active thermal control technique to improve the reliability of PSDs in the buck APD circuit. The proposed technique reduces the swing in junction temperature of PSDs using noninvasive power loss modulation. The power loss in PSDs is changed by varying the average voltage across the buffer capacitor. Further, a control technique is suggested to synthesize the reference for average voltage across buffer capacitor. This controller accounts for nonlinearities and minimum/maximum limits of power loss modulation. Further, the additional energy loss due to power loss modulation is restricted to a predefined limit. The proposed technique is validated with the help of circuit simulations and experimental studies with a 500 W laboratory prototype. For the selected mission profile, an increase of 28.5% in the lifetime of PSDs in buck APD circuit is estimated.

Design principles of digital-to-analog conversion in information transformation

The object of study is digital-to-analog converter (DAC). The meaning of DAC, their design and control of various types of switches, as well as some logic elements that can act as a switch, as well as the principles of DAC operation based on various series, microcircuits were considered. The resistance of a 4-bit DAC circuit was calculated and, accordingly, the change in the output voltage when applying the corresponding combined input voltage was studied, and a timing diagram was accordingly developed. Using 1-state and toggle physical switches, schematics are established and side effects are learned. Ladder circuit established using R–2R type dividers as voltage dividers. The object of the research is to find and learn the most technologically advantageous concept in order to provide good communication between all equipments by transferring information from digital to analog in the industrial field as well as in other areas where automation is used. One of the biggest challenges in this research is to determine the smallest binary values. Before the use of electronic logic elements such as counters, bistable physical switches were used to create a break or connect state in the circuit, which caused additional energy and time loss or abrasion because of large voltages occur across the switches. The biggest issue was that when manufacturing integrated digital-to-analog converters, producing the right resistors with very different values is really difficult. As a result of this research, it is seen that the use of physical switches is unnecessary as a demand of today's modern technology, and integrated microcircuits are good to replace them. The programming of digital-to-analog converters on programmable hardware devices such as Arduino and Raspberry Pi were mentioned. If to predict the near future, digital-to-analog transmission will be realized only by only using logic elements, and this will change both their energy efficiency and size for the better.

Aerodynamic performance investigation of an axial flow compressor under water ingestion

This paper presents numerical simulations of the effects of water ingestion in the axial flow compressor. A self-compiled droplet-wall interaction model is used to study the impingement of the droplets and the film fragmenting process on the surfaces of the compressor blades, which also included the splashing effects. The blade profile has been divided into small regions to effectively apply the rough wall model to capture the film-related flow losses, which has shown flow characteristics with better accuracy. The formation of water film, its shedding, the size, and the movement of droplets after film peeling have been investigated using unsteady simulations at different time intervals. The increased loss of characteristics, shortening of the operating range, and change of flow velocity angle were observed with increasing water content. Moreover, the current research work shown that an increase in the amount of water has severe aerodynamic effects that caused the shock waves to move an upstream location with an increase in intensity. A higher blockage is generated in the tip section flow as the amount of the water increased. Tip losses were very dominant as water injection rate increased, resulting an additional energy loss and performance degradation.

The Structure of the Flow Behind the Last Stage of Steam Turbine at the Low Flow Rate Operating Conditions

Introduction. The results of experimental studies, which given in various scholarly research sources, have shown that changes in the flow structure and the formation of a breakaway near a bushing (with a decrease in power) begins in the outlet nozzle and gradually spreads towards the last stage of low-pressure cylinder. As a result, theefficiency of the low-pressure cylinder and the power unit decreases.Problem Statement. The data analysis has shown that recently powerful turbines often operate in off-design modes. This leads to changes in the flow structure (the appearance of the breakaway near a bushing and the vortex rotating in the inter-row clearance) and additional energy losses, especially in the flow path of low-pressu recylinder, leading to erosive wear of trailing edges of the working wheel due to the suction of wet steam from the condenser.Purpose. The purpose of this research is to consider the movement of the working medium behind the working wheel in the outlet nozzle of the low-pressure cylinder and to evaluate the development of the breakaway near a bushing in the axisymmetric setting under the low-flow conditions to obtain dependences that allow analyzing the operation of turbine stages with a large fanning and preventing the turbine operation under the low-flow rate conditions.Materials and Methods. The methods for mathematical modeling of the processes in the flowing part of the turbine under low-flow rate conditions have been chosen based on the experimental research of V.A. Khaimov.Results. The characteristics of the interaction of rotor blades with the breakaway near a bushing have been given. The dependences that enable determining the characteristics of the flow behind the working wheel when it flows out into the outlet nozzle have been obtained.Conclusions. The proposed analytical methodology allows the use of a rational approach to the operation under the low-flow rate conditions and the prevention of erosion wear of working blades trailing edges of the laststages of low-pressure cylinder.

A Review on Electric Vehicles Charging Strategies Concerning Actors Interests

Electric vehicles are becoming increasingly popular in societies and an important part of smart grids. Utility companies should be able to provide them with vital energy as they need electric energy instead of fuel, and this is where new challenges emerge in the network. In order to avoid causing utilities to incur additional energy and economic losses, researchers have proposed smart charging as a way to provide adequate energy to vehicles. When developing a charging schedule for a fleet of EVs, special considerations are made on variables such as energy, cost, and EVs milage. In this review paper, the importance of EVs integration into smart grids is studied, and then different methods to develop EVs charging scheduling are investigated. These methods can vary from optimization algorithms to learning-based, and game theory-based approaches. Then, as the considered system consists of three main actors, including EV users, the utility operator, and aggregators, a systematic review is conducted on these actors, and objectives related to each one are analyzed. Finally, research gaps related to the problem are studied. Researchers can use this review to conduct further research on the integration of EVs into smart grids.

Quantum dots of graphene oxide as nano-additives trigger macroscale superlubricity with an extremely short running-in period

Achievement of macroscale superlubricity with liquid usually requires a long running-in period, which can reach several hours for ceramic materials, leading to severe wear and additional energy loss. In this study, we successfully solve the problem using graphene oxide quantum dots (GOQDs) as nano-additives in ethylene glycol aqueous solution, which can make the coefficient of friction between Si3N4 and sapphire reduce to 0.0068 (superlubricity state) with only a running-in period of 6 s. The running-in period is shortened by 95.7%, and meanwhile, the wear volume is also reduced by 90.0%, comparing to that lubricated by ethylene glycol aqueous solution in the absence of GOQDs. Our study provides direct evidence that the formation of tribofilm consisting of GOQDs is critical for achieving of superlubricity with extremely short running-in period, which can provide boundary lubrication and significantly enhance the load carrying capability of tribofilms. These findings provide insights of the interfacial structural governed superlubrication behaviors, which can aid the development of superlubricity systems with a limited running-in period and reduced wear for industrial applications.

Material flow cost accounting (MFCA) to enhance environmental entrepreneurship in the meat sector: Challenges and opportunities

The material flow cost accounting (MFCA) is one of the most broadly standardized tools accepted in environmental, social and economic research, which traces and quantifies material flows and stock in physical and economic units. Although its application has been recently developed in the field of resource and waste management, few academic articles have investigated its value towards food waste management, which represents a topical concern on a global scale. The present research applies the MFCA to investigate the material, energetic and economic costs associated with the Italian beef, pork and poultry production, exploring related challenges and opportunities towards the enhancement of the environmental entrepreneurship in the meat sector. The present countryside analysis is based on literature and empirical data collected during the Covid-19 pandemic. It highlights the need to improve knowledge on food waste issue under the economic perspective and its dual impact: when it is generated, in terms of income losses due to by-products and finished products sales failure, and when it is disposed, in terms of disposal costs sustained by farms, processing plants and distribution and sales centers. It is estimated that more than 0.45–0.50 Mt of fresh meat is wasted along the entire Italian agri-food chain, equal to more than 242–268 million euros, to which additional energy and water losses should be added (435–481 million euros). MFCA results are useful for business decisions, highlighting quantities, qualities and costs otherwise not considered in common financial reports.

About Electric Energy Additional Losses Reduction at the Phase Currents Unbalancing in the 0.38 kV Operating Networks

The materials of operation unbalancing modes studies in operating distribution electric 0.38 kV networks are presented. For research, electric energy parameters systematic measurements materials and its indicators characterizing the power quality have been used. The measurements were made by an electric grid organization order that provides to facilities power supply in the Irkutsk region. To assess the unbalancing modes, in accordance with the developed calculating the currents and voltages unbalance methods, the program “Imbalance-2" was created to determine these indicators. As a minimizing additional losses means, a special shunt-balancing device is used, which has the lowest possible zero-sequence currents resistance, which automatically changes its parameters. The program provides the device parameters determination in accordance with the changing current unbalance level at any time moment. Based on the created algorithm, the indicators characterizing the power quality, as well as additional power and energy losses caused by this unbalance are calculated and analyzed. It is established that the power quality meets the State Standard requirements, but the additional losses level is quite high. The full power total losses in the individual electrical network elements have been determined and the balancing device efficiency degree to reduce these losses are established. The used balancing device economic efficiency is determined.

Electrochemical deposition of amorphous cobalt oxides for oxygen evolution catalysis.

The oxygen evolution reaction (OER) is crucial in water splitting for hydrogen production. However, its high over-potential and sluggish kinetics cause an additional energy loss and hinder its practical application. The cobalt spinel oxide Co3O4 exhibits a high catalytic activity for the OER in alkaline solutions. However, the activity requires further enhancement to meet the industrial demand for hydrogen production. This paper presents an electrochemical deposition method to obtain cobalt oxides with a controllable crystallinity on carbon paper (CP). Usually, cobalt oxides grown on CP have a Co3O4 spinel oxide structure. The self-supported Co3O4/CP exhibited a considerable catalytic activity for the OER. When a VS2 layer grown on the CP beforehand by a hydrothermal method was used as substrate, the deposited cobalt oxides were in an amorphous state, denoted as CoOx/VS2/CP, which exhibited a higher OER activity and better stability than those of Co3O4/CP. The enhancement in the catalytic activity was attributed to the mixture formation of different types of cobalt species, including Co3O4, CoO, Co(OH)2, and metallic Co, because of the reduction by VS2. We also clarify the significance of the crystallinity of cobalt oxides in the improvement in the OER activity. This process can also be applied to the direct formation of other types of self-supported oxide electrodes for OER catalysis.

Impact of Hydraulic System Stiffness on Its Energy Losses and Its Efficiency in Positioning Mechanical Systems

Hydraulic steering systems for mechanical devices, for example, manipulators or vehicle steering systems, should be able to achieve high positioning precision with high energy efficiency. However, this condition is very often not met in practical applications. This is usually due to the stiffness of the hydraulic system being too low. As a result, additional corrections are required to achieve the required positioning precision. Unfortunately, this means additional energy losses in the hydraulic control system. In this study, this problem is presented using the example of a hydraulic steering system for an articulated frame steer vehicle. This hydraulic steering system should provide the required directional stability for road traffic safety reasons. So far, this issue, connected mainly with the harmful phenomenon of so-called vehicle snaking behaviour, has not been solved sufficiently practically. To meet the needs of industrial practice, taking into account the current global state of knowledge and technology, Wrocław University of Science and Technology is performing comprehensive experimental and computational studies on the snaking behaviour of an articulated frame steer wheeled commercial vehicle. The results of these tests and analyses showed that the main cause of problems that lead to the snaking behaviour of this vehicle class is the effective torsional stiffness of the hydraulic steering system. For this reason, a novel mathematical model of the effective torsional stiffness was developed and validated. This model comprehensively took into account all important mechanical and hydraulic factors that affect the stiffness of a hydraulic system, resulting in the examined snaking behaviour. Because of this, it is possible at the design stage to select the optimal parameters of the hydraulic steering system to minimise any adverse influence on the snaking behaviour of articulated frame steer wheeled vehicles. This leads to minimising the number of required corrections and minimising energy losses in this hydraulic steering system. The innovative model presented in the article can be used to optimise positioning accuracy, for example, in manipulators and any mechanical system with hydraulic steering of any system of any mechanical parts.

Enhancement of Lithium in Red Clump Stars by Neutrino Magnetic Moments

A recent spectroscopic survey has shown that the lithium abundances in low-mass red-clump stars are higher than theoretical prediction. Motivated by their finding, we implemented effects of additional energy losses induced by neutrino magnetic moments on stellar evolution models. It is found that the lithium abundances in red giants increase because the finite magnetic moments of neutrinos enhance the efficiency of deep mixing and 7Be is conveyed from the hydrogen burning shell to the convective envelope. The results motivate further studies on the effects of non-standard energy losses on the surface compositions of low-mass red giants and red-clump stars.

The Effects of Bubble Scattering on Sound Propagation in Shallow Water

As sea waves break, a bubble layer forms beneath the sea surface. The bubble scattering affects sound propagation, thus influencing the accuracy of sound field prediction. This paper aims to investigate the effects of bubble scattering on the statistical characteristics of the sound field, the distribution of transmission loss (TL), and the average scattering attenuation in shallow water. A bubble layer model based on the bubble spectrum and a parallel Parabolic Equation (PE) model are combined to calculate and analyse the sound field in the marine environment with bubbles. The effects of the bubble layer are then compared with those of the fluctuant sea surface. The results show that the bubble scattering causes additional energy loss and random fluctuations of the sound field. The TL distribution properties and the average scattering attenuation are related to the wind speed, range, frequency, and source position relative to the negative gradient sound speed layer in shallow water. The comparison demonstrates that the random variation caused by the fluctuation of the sea surface is more significant than that caused by bubbles, and the energy loss caused by bubble scattering is more significant than the fluctuant sea surface under strong wind conditions.

Analysis of energy losses in electric transmis-sion taking into account the Sommerfeld – Kononenko effect

The use of an electric drive in modern vehicles allows solving a number of problems related to the issues of environmental and energy security of the country. However, this approach imposes a number of practical limitations. Among them there is such a significant factor as the limitation on the stored energy in the traction batteries and, as a consequence, the limitation of the mileage on one charge. One of the ways to solve this problem is to reduce mechanical losses associated with the appearance of resonance phenomena in rotating transmission elements and having an unbalanced mass. Goal. The goal is to assess the influence of the Sommerfeld – Kononenko effect on energy indicators during the transfer of rotation from the electric motor to the drive wheel of an electric vehicle.
 To achieve this goal, it is necessary to determine the law of motion of the rotor of an electric motor and a car wheel using the energy approach and a model of complex motion. Methodology. To solve the problem of determining the law of rotation of an electric motor rotor, a dynamic model of an eccentric vibrator is adopted. The study takes into account the fluctuations in the angular velocity of the shaft with Hooke's hinge when the shaft axis deviates from horizontal positions. It is proposed to apply an energy approach using a model of complex motion to determine the law of rotation of an electric motor rotor and a wheel. Results. The dependence of the speed of rotation of the wheel of an electric vehicle is determined in accordance with the dynamic model under the conditions of fluctuations in the angular speed of transmission elements with Hooke's hinge when the wheel axis deviates from the horizontal position. Practical value. An energy approach is proposed for finding losses in a complex motion model to determine the law of rotation of an electric motor rotor and a wheel.
 An analytical dependence of additional energy losses caused by wheel unbalance on vehicle mileage and wheel unbalance is found.

Evaluation of flow resistance equations for high gradient rivers using geometric standard deviation of bed material

A dataset of 2184 field measurements reported in the literature was used to evaluate the predictive capability of eight conventional flow resistance equations to predict the mean flow velocity in gravel-bed rivers. The results reveal considerable disagreement with the observed flow velocities for relative submergence less than 4 and for the non-uniformity of the bed material greater than 7.5 for all the equations. However, the predictions made using the Smart and Jäggi (1983), Ferguson (2007), and Rickenmann and Recking (2011) equations were closer to the observed values. Furthermore, bedload sediment transport also reduces the predictive capability of the equations considered in this study except for the Recking et al. (2008) equation, which was developed considering active bedload transport. The performance of flow resistance equations improves when corrected by considering the geometric standard deviation of the bed material. Here we present an empirical approach using the whole dataset and its subsets for accounting for the additional energy losses occurring due to the wake vortices, spill losses, and free surface instabilities occurring due to the protrusions from the bed. The results obtained using the validation dataset shows the importance and usefulness of this approach to account for the additional energy losses, especially for the Strickler (1923) and Keulegan (1938) equations.

Probabilistic impact assessment of phase power imbalance in the LV networks with increasing penetrations of low carbon technologies

Phase imbalances cause a range of network issue, from day-to-day energy losses to long-run capacity wastes that increase investment costs. The impact on low voltage (LV) network from phase imbalance has been investigated independently for losses and investment. However, no research was carried out on the total imbalance-induced cost (TIC) that includes both day-to-day energy losses and long-run capacity wastes, and how the relationship between the two may change with the increasing penetrations of single-phase low carbon technologies (LCTs). Analyzing the TIC is important for distribution network operators (DNOs) as the day-to-day energy loss cost cannot be ignored as it may exceed the long-run network investment cost. This paper develops a new probabilistic framework to investigate the impact of increasing LCT penetration on TIC in the UK's LV distribution networks. Monte Carlo simulations are performed to account for the uncertainties in LCT sizes, connection locations and connection time. Case studies show that the additional energy loss cost exceeds the additional reinforcement cost in urban networks when the LCT penetration level reaches 70%. The key findings will help the DNOs understand the range of TIC and the relationship between imbalance-induced energy losses and capacity wastes under increasing LCT penetrations.
