Evaluation of a hybrid power system based on renewable and energy storage for reliable rural electrification

Microgrids system consisting of single or multiple energy resources and storage is used to provide electricity to remote rural areas. Subsequently, they can be worked in both grid-connected and islanded modes. Microgrids can provide stable energy solutions to areas where grid extension is either costly or not feasible. The system's long-term economic stability and sustainability must be considered throughout the microgrid's design. Renewable energy sources have a variety of objectives and possible restrictions. The current plan suggests a rural microgrid with integrated solar, diesel, and battery systems. The proposed microgrid for the rural area of Uttarakhand (India) is given a techno-economic and feasibility analysis. For the hilly region of India, a standalone microgrid is created to handle the home peak load of 13kW. Moth flam optimization (MFO) is utilized to optimize the proposed energy framework, and the results are compared with those of a genetic algorithm (GA) and particle swarm optimization (PSO). The optimal hybrid system's net current and energy costs are calculated to be $58372.00, with the cost of energy per unit being $0.14/kWh. Sensitivity analysis and robustness viability have been performed for the configuration. The finding suggested that the energy framework using MFO is 18% and 16% less expensive than GA and PSO, respectively. This research adds new direction to critical sustainable development among developed countries.

Study on separation of long carbon chain aromatics/alkanes in diesel systems with DBU-based ionic liquids

Based on the structural designability of ionic liquids (ILs), 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU)-based ILs ([Bz-DBU]NTF2) were designed and synthesized. Their physical properties were analyzed by FT-IR, 1H NMR, DSC and TGA. Highly selective separation between aromatic and alkane by [Bz-DBU]NTF2 was achieved. Under the optimal conditions, the distribution coefficient (D) and separation selectivity (S) of [Bz-DBU]NTF2 for tetraline were 0.833 and 54.2. The IL was regenerated six times without decrease in separation selectivity, demonstrating good stability. For the multi-component simulated diesel, nearly 100% of the bicyclic alkanes could be removed by five-stage cross-flow extraction processes. While the removal rate of total aromatics reached up to 84.39 and the contents of alkanes and total saturated alkanes reached 56.64% and 96.69%, respectively. For the real diesel, after two-stage cross-flow extraction experiments, the removal rates of monocyclic, bicyclic, tricyclic aromatic hydrocarbons reached 63.9%, 91.3% and 100%, respectively. The final product reached the standard of high quality ethylene cracking feedstock.

Optimal design of PI/PD dual mode controller based on quasi opposition based learning for power system frequency control

Due to uncertain load deviations in the unified power system, it becomes more challenging to uphold the system frequency at a constant desired value. The secondary controller has a significant role in damping the oscillations of frequency and interline power at a faster rate. Here a novel PI/PD dual mode controller (DMC) is suggested to regulate the frequency of unified system comprising renewable and conventional sources of power generation. The various sources of generation instigated in the dual-area system are hydro, diesel, thermal, PV, wind and battery energy storage system (BESS). The gains of the PI/PD DMC are suitably obtained by the novel application of quasi opposition based Sine Cosine Algorithm (QOBSCA) algorithm. The dynamic outcomes of the model are examined with the application of abrupt load deviation of 0.02 per unit in control area 2. During this deviated loading condition QOBSCA algorithm is utilized to achieve the appropriate gains of PID and PI/PD dual mode controller in view of a time based fitness function denoted as integral time absolute error (ITAE). Considering few response evaluative indices like overshoots, settling time and undershoots the ascendency of the projected PI/PD dual mode controller is recognized over popular PID controller during the abnormal loading condition. Additionally, the efficacy of the mentioned PI/PD dual mode controller is verified by applying arbitrary load pattern in control area 2. The robustness of the mentioned control schemes is also evidenced by confirming the stable response during system parameter deviations.

Competitive Adsorption in a Multicomponent Diesel System Using Nickel Oxide/Activated Carbon

Nickel oxide, which acts as an intermediate Lewis acid, was loaded onto activated carbon (AC) to enhance the adsorption selectivity of AC in the desulfurization of model diesel. The total sulfur adsorption capacity increased from 2.46 to 4.42 mg-S·g adsorbent–1 and the total sulfur removal increased from 46.8 to 84.5% using the AC and Ni(10%)O/AC adsorbents, respectively. Multicomponent isothermal modeling showed that the incorporation of NiO onto AC significantly improved the synergistic interactions between the thiophenic compounds while mitigating competitive interactions between the more steric 4,6-dimethyl dibenzothiophene (4,6-DMDBT) and 4-methyl-dibenzothiophene (4-MDBT) compounds. The mitigation was attributed to new adsorbate-specific sites created by loading NiO on AC. Spent adsorbent characterization and pyridine adsorption-IR analysis suggested that higher desulfurization performance of the Ni(10%)O/AC adsorbent was attributed to an increase in the adsorbent’s Lewis acidity upon loading with NiO, leading to increased Ni–S acid–base interactions, in addition to π-complexation.

Impacts of Arctic diesel contamination on microbial community composition and degradative gene abundance during hydrocarbon biodegradation with and without nutrients: A case study of seven sub-Arctic soils

Although a number of studies have assessed hydrocarbon degradation or microbial responses in petroleum contaminated soils, few have examined both and/or assessed impacts in multiple soils simultaneously. In this study petroleum hydrocarbon biodegradation and microbial activity was monitored in seven sub-Arctic soils at similar levels (∼3500–4000 mg/kg) of Arctic diesel (DSL), amended with moisture and nutrients (70 mg–N/kg, 78 mg–P/kg), and incubated at site-representative summer temperatures (∼7 °C) under water unsaturated conditions. Total petroleum hydrocarbon (TPH) biodegradation extents (42.7–85.4 %) at 50 days were slightly higher in nutrient amended (DSL + N,P) than unamended (DSL) systems in all but one soil. Semi-volatile (C10-C16) hydrocarbons were degraded to a greater extent (40–80 %) than non-volatile (C16-C24) hydrocarbons (20–40 %). However, more significant shifts in microbial diversity and relative abundance of genera belonging to Actinobacteria and Proteobacteria phyla were observed in DSL + N,P than in DSL systems in all soils. Moreover, higher abundance of the alkane degrading gene alkB were observed in DSL + N,P systems than in DSL systems for all soils. The more significant microbial community response in the DSL + N,P systems indicate that addition of nutrients may have influenced the microbial community involved in degradation of carbon sources other than the diesel compounds, such as the soil organic matter or degradation intermediates of diesel compounds. Nocardioides, Arthrobacter, Marmoricola, Pseudomonas, Polaromonas, and Massilia genera were present in high relative abundance in the DSL systems suggesting those genera contained hydrocarbon degraders. Overall, the results suggest that the extents of microbial community shifts or alkB copy number increases may not be closely correlated to the increase in hydrocarbon biodegradation and thus bioremediation performance between various treatments or across different soils.

Estimating Battery Size Requirements for Tractor Electrification of Row-Crop Planting Operations

Highlights Calculate and compare engine power needed for row-crop planting from ASAE standards and reported CAN data. Estimate energy requirements and the equivalent electric battery’s volume and mass for row-crop tractor. Discuss the feasibility for electrification of a fully electric row-crop tractor. Abstract. Power sources such as batteries, used for both on-road and off-road vehicles, are advancing at a rapid pace. Electric batteries are becoming more power dense, thus allowing them to be used as a power source to replace previous diesel or gasoline-powered systems. Efforts are underway to transition off-road agricultural vehicles from Internal Combustion Engine (ICE) vehicles to electric vehicles (EVs); however, the energy requirements of typical agricultural field operations need to be fully understood before such a transition can occur. Theoretical prediction equations available in the American Society of Agricultural and Biological Engineers (ASABE) standards or the use of engine load data from a tractor’s Controller Area Network (CAN) bus are two methods for determining the energy demands of implements on tractors. In this study, tractor CAN bus data was collected from multiple no-till corn planting operations to estimate the energy requirements of the planting operation in kWh. The estimated energy requirement was used to determine the equivalent physical mass and volume of a lithium-ion battery needed to power a hypothetical fully electric tractor for comparable planting operations. The estimated battery capacities using the worst-case field-use scenario in this study were 1117 kWh for operating a 16-row planter to plant 68 ha (168 acre) in a day at an average ground speed of 8.6 km h-1 (5.4 mph) for 14 hours, and 2658 kWh for operating a 48-row planter to plant 158 ha (391 acre) in a day at an average ground speed of 8.9 km h-1 (5.6 mph) for 15 hours. Given the current battery energy density requirements, the equivalent battery masses and volumes were found to be 5,319 kg and 3.33 m3, 12,657 kg and 7.93 m3, for 16-row planter and 48-row planter, respectively. These high kWh estimates needed to power future fully-electric tractor power units are based on worst-case scenarios that could be encountered in real field operations that use wide planters over long operating hours.

Features of starting motor vehicles diesel engines with the use of molecular energy storages

Problem. With the experience of special purpose vehicles operating in the field, there is a problem of electrical start-up of diesel engines at low temperatures.

The functional scheme of the electrical start-up system of diesel with a molecular energy storages is proposed. Originality. There are the known ways to facilitate the launch of diesel engines in low temperatures, such as the engine pre-growing or the heating of the air entering the engine combustion chambers, but they lead to a rapid discharge of starter batteries. This may make it impossible to start the diesel engine. The use of molecular energy storage will ensure a reliable start-up of a cold diesel engine. Practical meaning. The use of a combined electricity source, consisting of batteries and molecular energy storage, provides a reliable start-up of the engine in extreme temperature conditions, reducing the batteries capacity, increasing their service life, and cutting down operating costs.

Techno-Economic and Environmental Analysis of Renewable Mix Hybrid Energy System for Sustainable Electrification of Al-Dhafrat Rural Area in Oman

Affordable and clean energy for any rural community is crucial for the sustainable development of the community and the nation at large. The utilization of diesel-based power generation is one of the barriers to the sustainable development of these communities. Such generations require fuel that has a volatile market price and emits massive greenhouse gas emissions. This paper presents the design, modeling, and simulation of a hybrid power system for a rural area in the Sultanate of Oman that aims to reduce daily consumption of diesel fuel and greenhouse gas emissions. Hybrid Optimization of Multiple Energy Resources (HOMER) is utilized to model multiple energy mix hybrid systems and to propose the best optimal energy mix system for a selected community. In addition, Electrical Transient Analyzer Program (ETAP) software is employed to assess hybrid system operational performances, such as bus voltage profiles and active and reactive power losses. This study revealed that the PV–wind–diesel system is the optimal energy mix hybrid microgrid for the Al-Dhafrat rural area in Oman, with a net present cost of USD 14.09 million. Compared to the currently operating diesel-based system, the deployment of this microgrid can reduce the levelized cost of energy, diesel fuel consumption, and greenhouse gas emissions per year by 54.56%, 70.44%, and 70.40%, respectively. This study confirms that the Sultanate of Oman has a substantial opportunity to install a hybrid microgrid system for rural diesel-based communities to achieve sustainable development in the country.

An experimental study on the needle valve motion characteristics of high pressure natural gas and diesel co-direct injector

To reveal the gas needle valve dynamic characteristics of the high pressure natural gas and diesel co-direct injector, an innovative non-intrusive needle valve motion characteristics measurement method is proposed. The influence of needle valve movement on injection rate is investigated, and the effect of diesel pressure fluctuation on needle lift process is revealed. The results indicated that the lifting speed of the needle increases with the increase of gas injection pressure. Under the same injection pressure, the displacement curve of the needle valve changes from triangle to trapezoid with the increase in energizing time. Due to the change of the gas flow throttle position, the injection rate does not correspond linearly with the needle displacement curve. In the process of needle upstroke, there are two different velocities in the rising process of the injection rate. Furthermore, in the diesel system, the compression wave reflected from the common rail has a significant influence on the needle dynamic characteristics and injection rate which becomes more obvious with the decrease in injection pressure. Under the action of reflected compression wave, the moment delay of needle reaching the maximum position can reach 0.6 ms, and the gas injection mass can be reduced by 16%.

Feasibility of solar hybrid energy system at a conservation park: Technical, economic, environmental analysis

Access to clean, reliable, affordable energy has become vital for sustainable development. However, such energy facilities are still unavailable in many rural areas worldwide. The implementation of the clean energy system in remote locations is often challenging. This paper aims to design a hybrid energy system for a conservation park and analyze its technical, economic, and environmental performance. A campsite located in Royal Belum State Park, Malaysia, is chosen as a case study. HOMER Pro software is used to assess the feasibility of different system configurations. In terms of net present cost (NPC), the best system configuration is a 4.13 kW PV array, 11 kWh battery bank, and 0.85 kW converter. It is followed by a PV/DG/Battery system with an NPC of 12767.91 USD. A rise in battery capacity, energy generation, and the initial cost are observed with the increase in the share of PV capacity. It was understood that the PV/DG/Battery hybrid system is technically superior to the standalone diesel system in terms of renewable energy fraction and energy storage autonomy. In terms of economic performance, the PV/DG/Battery system fares better than other configurations with the lowest cost of electricity, payback period, and highest return on investment. High carbon avoidance and negligibly small carbon emission are the unique benefits expected from PV/Battery configurations. In this study, PV/Battery is expected to avoid around 3407.39 kgCO2 annually. This study is expected to shed light on designing an effective hybrid energy system at a conservation park.

A REVIEW ON THE FREQUENCY RESTORATION IN A TWO AREA POWER SYSTEM

In the process of achieving frequency restoration in multi area multi source, we came across several problems. First one is to place a controller to maintain and tune the gain parameters of different generation units to get the optimal response by proper optimization technique to simulate the environment for finding the optimal values. Here we are analyzing the Hybrid Differential Evolution Pattern Search based Fuzzy PID controller for AGC of multi area power system. In this work, a two area six-unit hydro, thermal, wind and diesel system were examined. Area-1 consists of hydro + thermal +wind and area-2 consist of hydro +thermal + diesel which is interlinked with a tie-line. The future scope will be on simulation results which validate the present work of hybrid pattern search differential evolution (HPS-DE) with other techniques in terms of frequency deviation, tie-line power deviation. KEY WORDS: Frequency Restoration, Fuzzy PID, HPS-DE, power generation, multi area multi source.

Feasibility study and performance analysis of microgrid with 100% hybrid renewables for a real agricultural irrigation application

Recently, wide attention has been paid to the techno-economic viability for electrifying rural and remote areas while less awareness for agricultural irrigation pumps is given. Diesel generators are still utilized for agricultural facilities, causing ecological issues and energy price growth. In this paper, an integrative techno-economic design optimization framework for adequate planning of fully renewable energy system including photovoltaic units, wind turbines and batteries fed a real case-study of an agricultural load of 240 kWh/day in Al-Sadat city, Egypt, is proposed using HOMER Pro. The project site is favorably chosen since Egypt holds great potential for renewables; manipulating these resources becomes crucial for achieving national sustainability as per Egypt 2030 vision. The feasibility and performance of the proposed energy system are evaluated and analyzed regarding its technical and economic dimensions and compared with four different energy alternatives, including the existing real system and the standalone diesel system, for fair comparisons. The design optimization is followed by parametric and reliability analyses to uncover the impacts of uncertainty in seven key input parameters and power generation shortage on optimal economic behavior. The achieved outcomes reveal that the fully renewable solar/wind/batteries/converter system is of optimal behaviours over other alternatives to fulfil the load demand. The proposed system acquires the minimum net present cost ($194,017) and cost of energy (0.119 $/kWh) and efficiently attains a negligible ratio in both capacity shortage and unserved load with only 0.098%. Besides, a productive amount of surplus energy (61.7%) is achieved for further deferable loads supplying. Moreover, the parametric analysis proves the great reliance of system cost on the uncertainty of discount rate, project lifetime and components’ capital costs while the uncertainty in renewable resources has a slight impact on the system performance. In addition, the reliability analysis indicates that a small and tolerable loss of power supply by 2% results in considerable financial benefits while optimizing the microgrid design. The study is expected to raise the awareness of exploiting renewable energy in Egypt and provide a valuable proposal for replacing the existing energy system of the addressed case-study.

Расчет и проектирование форсунок Common Rail с учетом их продольной податливости

The experience of creating electro-hydraulic Common Rail injectors led to the conclusion that the longitudinal deformation of their parts affects the fuel supply performance. The paper presents additions to the mathematical model of fuel supply in a diesel accumulator system. These additions describe the deformation of the injector parts. The longitudinal compliance of the parts changes the course of the needle, the volume of the cavities. As shown by the analysis of the operation of three electro-hydraulic injectors, longitudinal compliance leads to an increase in the injection start delay up to 2,0...2,5° of the camshaft turn, an increase in the needle stroke up to 40 %, an increase in injection pressure, a reduction in its duration, and difficulty in organizing multiple fuel injection. The comparison with experimental data and finite element calculations showed the applicability of the supplemented mathematical model as a part of the general model of fuel injection in diesel systems. Its use allows creating more valid tools for calculating fuel supply processes and taking into account compliance when designing Common Railinjectors.

Optimizing the performance of hybrid renewable energy systems to accelerate a sustainable energy transition in Nigeria: A case study of a rural healthcare centre in Kano

The COVID-19 pandemic brought tremendous pressure to the African continent's health sector, particularly in rural areas. Rural healthcare facilities experienced severe energy shortages due to the influx of Covid-19 patients, which strained their operating capacities. These facilities usually rely on diesel engines, and this unidirectional approach limited governments' vision in resolving the energy crisis. This paper aims to develop a hybrid energy system (HES) that combines alternate energy sources available at a rural healthcare centre in northern Nigeria and conduct a techno-economic analysis of the viability of such systems. The energy potential of available energy resources at the target location and comparison of various HES configurations were estimated with HOMER Pro software to determine the most feasible choices. These choices were analyzed for technical, financial, and environmental viability using RETScreen Expert. Due to an abundance of solar energy, low diesel cost, and sufficient wind energy potential, the results show PV – Diesel and Wind – Diesel system HES configurations as the only practical choices. Techno-economic analysis indicates that the PV – Diesel HES produces annual savings of $30,583 with a Net Present Value (NPV) of $390,949 compared to $15,174 and $193,980 for the Wind – Diesel configuration. Further analysis solidifies the PV-Diesel HES as the best choice with a payback period of 1.3 years, 75 tons of CO2 emission reduction, and annual savings of $30,583 compared to the initial diesel energy system.

Techno-Economic Analysis of Hybrid Diesel Generators and Renewable Energy for a Remote Island in the Indian Ocean Using HOMER Pro

This study is about the electrification of the remote islands in the Indian Ocean that were severely affected by the tsunami in the 2004 earth earthquake. To supply electricity to the islands, two diesel generators with capacities of 110 kW and 60 kW were installed in 2019. The feasibility of using renewable energy to supplement or replace the units in these two generators is investigated in this work. In 2019, two diesel generators with capacities of 110 kW and 60 kW were installed in the islands to supply electricity. This work analyses whether the viability of using renewable energy can be used to supplement or replace these two generators. Among the renewable energy options proposed here are a 100 kW wind turbine, solar PV, a converter, and batteries. As a result, the study’s goal is to perform a techno-economic analysis and optimise the proposed hybrid diesel and renewable energy system for a remote island in the Indian Ocean. The Hybrid Optimisation Model for Electric Renewable (HOMER) Pro software was used for all simulations and optimisation for this analysis. The calculation is based on the current diesel price of USD 0.90 per litre (without subsidy). The study found that renewable alone can contribute to 29.2% of renewable energy fractions based on the most optimised systems. The Net Present Cost (NPC) decreased from USD 1.65 million to USD 1.39 million, and the levelised Cost of Energy (CoE) decreased from 0.292 USD/kWh to 0.246 USD/kWh, respectively. The optimised system’s Internal Rate of Return (IRR) is 14% and Return on Investment (ROI) 10%, with a simple payback period of 6.7 years. This study shows that it would be technically feasible to introduce renewable energy on a remote island in Indonesia, where numerous islands have no access to electricity.

Techno-Economic Feasibility of a Solar-Wind-Fuel Cell Energy System in Duqm, Oman

Duqm is located in the Al Wasta Governorate in Oman and is currently fed by 10 diesel generators with a total capacity of around 76 MW and other rental power sources with a size of 18 MW. To make the electric power supply come completely from renewables, one novel solution is to replace the diesel with hydrogen. The extra energy coming from the PV-wind system can be utilized to produce green hydrogen that will be utilized by the fuel cell. Measured data of solar insolation, hourly wind speeds, and hourly load consumption are used in the proposed system. Finding an ideal configuration that can match the load demand and be suitable from an economic and environmental point of view was the main objective of this research. The Hybrid Optimization Model for Multiple Energy Resources (HOMER Pro) microgrid software was used to evaluate the technical and financial performance. The findings demonstrated that the suggested hybrid system (PV-wind-fuel cell) will remove CO2 emissions at a cost of energy (COE) of USD 0.436/kWh and will reduce noise. With a total CO2 emission of 205,676,830 kg/year, the levelized cost of energy for the current system is USD 0.196/kWh. The levelized cost for the diesel system will rise to USD 0.243/kWh when taking 100 US dollars per ton of CO2 into account. Due to system advantages, the results showed that using solar, wind, and fuel cells is the most practical and cost-effective technique. The results of this research illustrated the feasibility and effectiveness of utilizing wind and solar resources for both hydrogen and energy production and also suggested that hydrogen is a more cost-effective long-term energy storage option than batteries.

Electro-thermal modelling of redox flow-batteries with electrolyte swapping for an electric ferry

Vanadium redox flow-batteries in coastal ferry applications have the potential to help bring down the carbon footprint of the shipping industry. There is a lack of research focused on vanadium redox flow-batteries in transport applications due to their low energy density, though electrolyte swapping offers benefits whereby the depleted electrolyte can be rapidly exchanged for a fully charged supply. Vanadium redox flow-batteries also benefit from significantly higher cycle life when compared to Li-ion and fuel cell technologies, offering potential for lower cost per year of ownership. A vanadium redox flow-battery coastal ferry is electro-thermally modelled to identify whether it is feasible in terms of energy capacity, temperature limits, carbon footprint and cost. The ferry journeys between two ports, where each port is equipped with a flow-battery to provide electrolyte swapping. An Equivalent Circuit Model is utilized to model the battery response, while the thermal model predicts the electrolyte temperature based on the conservation of energy. Shunt current and pumping losses are considered in the model. It was found that vanadium redox flow-batteries show real potential for the decarbonisation of the shipping industry. Battery temperature is kept within the safe operating limits, while offering a cost per voyage close to that of a diesel system, with significant reductions in CO2 output.

Assessing Land Use Efficiencies and Land Quality Impacts of Renewable Transportation Energy Systems for Passenger Cars Using the LANCA® Method

Targets to reduce global warming impacts of the transportation sector may lead to increased land use and negative land quality changes. The aim of this paper is to implement the Land Use Indicator Calculation in Life Cycle Assessment (LANCA®) model to assess land quality impacts and land use efficiencies (concerning occupation and transformation) of different example renewable transport energy systems for passenger cars. In addition, the land use impacts are normalized according to the Soil Quality Index building on LANCA® and included in the environmental footprint. The assessment is based on information from GaBi life cycle assessment software databases and on literature. Functional unit of the model is to provide annual drive of 18,600 km for a passenger car in the EU. The analysis includes examples of biomass, electricity, electricity to fuels and fossil-based energy systems. Our findings confirm previous research that biomass-based transport energy systems have risks to lead to significantly higher land occupation and transformation impacts than do fossil oil or electricity-based ones. According to the LANCA® model, methane from Finnish wood and German corn has the highest impacts on filtration and the physicochemical filtration reduction potential. Sugarcane ethanol and palm oil diesel systems, on the other hand, lead to the highest erosion potential. Electricity-based transportation energy systems appear to be superior to biomass-based ones from the perspectives of land occupation, land transformation, and soil quality impacts for the selected examples. Land quality impacts should be taken into account when developing and expanding renewable transportation energy systems. The paper shows that the LANCA® method is applicable for the assessment of transport systems in order to provide extended information on environmental sustainability, which should be included more often in future analysis. However, it can be challenging to interpret underlaying assumptions, especially when aggregated information is used from databases.
