Use Of Non-conventional Energy Sources Research Articles

Designing and software realization of an ANN-based MPPT-Fed bladeless wind power generation

The use of non-conventional energy sources has increased in recent years due to the benefits of low power interruptions, unlimited power supply, and non-polluting power generation. Wind power generation has become one of the clean energies whose use will be a viable solution to global warming and power outages. One such proposed system consists and modelling of bladeless wind power generation, which uses wind as an energy source while producing power without the use of blades. Due to the fact that wind energy isn’t really constant, an MPPT with an artificial neural network is being intended to keep the voltage and current of a bladeless wind generator at their maximum peak values regardless of whether environments. The wind generator’s outcome has been fed into a single-phase induction motor that can be used for pumping stations application fields. The proposed wind generator’s architecture as well as findings has been modeled using MATLAB Simulink.

Implementation of hybrid model Converter for Photovoltaic Applications

The increase in the use of non-conventional energy sources in our day to day life is to save our earth. The hybrid wind and photovoltaic power generation system allow supplying the load either individually or at the same time. This technique includes the Cuk and Sepic converters together and this eliminates the accessibility for extra input filters having high-frequency harmonics. The rapid changes in the atmospheric conditions can be control by using the Maximum Power Point Tracking technique because of its high tracking accuracy. To increase the output power and efficiency the Buck Boost and Sepic converters are used. Converters output ripple voltage can be reduced by the photovoltaic array voltage which can vary from 0 to 600V. The thin-film PV panels and the MPPT methodology is produced with the help of converters by reducing the stress occurred in voltage due to inverters and to work at 230V DC-bus voltage reducing Simulation is carried out MATLAB Simulink.

Transient Analysis of self excited Induction generator with ELC

— Fast depletion of fossil fuels has drawn attention towards the use of nonconventional energy sources like wind, biomass, tidal/wave, and small hydro potential. In remote locations, harnessing of electrical energy from such local resources can be cheaper and easier compared to grid connection, which involves long transmission lines and associated losses. A micro-hydro system using natural hydro potential with minimal civil works is a strong candidate in this race. Uncontrolled low head turbines are prescribed for such applications. In this paper, a transient analysis of a self-excited induction generator (SEIG) with electronic load controller (ELC) utilized in stand-alone micro-hydro power generation employing uncontrolled turbines. In view of the need to fed single phase loads from such systems, the transient behavior due to switching in of such loads is of interest and is carried out here. A composite mathematical model of the total system has been implemented by combining the modeling of prime mover, SEIG, ELC, and load. Simulated results are matched with the experimental ones, obtained on a implemented prototype of an SEIG-ELC system for the starting of an IM and switching in a resistive load. To starting of an IM, a star/delta starter is utilized to avoid inrush current.

Ultrasonically Assisted Efficient and Green Protocol for the Synthesis of 4H-isoxazol-5-ones using Itaconic Acid as a Homogeneous and Reusable Organocatalyst

Background: Multicomponent reactions involve the simultaneous reaction of three or more components which deliver the product that incorporates the elements of all starting materials. A combination of multicomponent reaction and green solvents like water and the use of nonconventional energy sources like microwave or ultrasonication are important features of ideal green synthesis. Therefore, the design of a new multicomponent reaction and improvement of an already known multicomponent reaction with a green procedure has attracted the attention of the scientific community. Isoxazole derivatives are well known for their biological activities such as antifungal, analgesic, antitumor, antioxidant, antimicrobial, COX-2 inhibitory, anti-inflammatory, antiviral, and antimycobacterial. Objective: To develop a green methodology for the synthesis of 4H-isoxazol-5-ones derivatives. Results: Itaconic acid was used as a green catalyst for the synthesis of 4H-isoxazol-5-ones derivatives under conventional as well as ultrasound irradiation technique. Ultrasound irradiation condition requires less time for the completion of the reaction and also the yields were better. Methods: We have reported Itaconic acid as a green homogenous organocatalyst under ultrasound irradiation for the synthesis of 4H-isoxazol-5-ones derivatives. Conclusion: In conclusion, we have developed a green methodology for the synthesis of 4Hisoxazol- 5-ones derivatives. Itaconic acid is used as an organocatalyst which is biodegradable and nonhazardous. Water is used as a green solvent. Ultrasonication is used as a non-conventional green energy source. Ambient reaction conditions are used to carry out transformation for multicomponent reaction. Metal-free, mineral acid-free synthesis are key features of the present protocol.

Understanding dynamics and policy for renewable energy diffusion in Colombia

Colombia has committed to reduce greenhouse gas emissions in 20% by 2030 with respect to business-as-usual in the COP21. One policy is the Renewable Energy (RE) law launched in 2014, aiming “to promote the development and use of non-conventional energy sources” with indirect incentives, such as tax reduction or exemptions. Direct incentives, such as price-based, are not included in the law. Experiences in other countries have proven that direct incentives are more efficient than indirect ones to promote RE. The purpose of this study was to evaluate incentives for RE diffusion in Colombia through a simulation model for energy policy recommendations. We tested four incentives: tax reduction, feed-in-tariffs, tradable certificates, and technical subsidies; and four RE sources: small hydro, biomass, wind, solar and geothermal. Simulation results show that a combined scenario using feed-in-tariffs and technical subsidies can boost the deployment of RE, avoiding significant price increases for the final consumer. None of the incentives leads to reaching the RE target, given the growing demand for energy. Complementary policies could focus on improving energy efficiency.

Performance Analysis of SPV Module Using Solar PVTR System

With a spurt in the use of non-conventional energy sources, photovoltaic installations are being deployed in several applications such as distributed power generation and standalone systems. Solar Photo Voltaic (SPV) module is the basic component of the solar PV system. The functioning of a photovoltaic array is influenced by solar insolation, shading and array arrangement. Often the PV arrays get shadowed, completely or partially by neighboring buildings, trees, towers and service poles. The efficacy of PV array unvaryingly depends upon temperature which in turn is reliant on radiation. In order to validate this hypothesis, there are certain instruments and experimentation methods available which are expensive. But carrying out hardware testing on the solar PV system with Photo Voltaic Training and Research (PVTR) system and simulating using software will lead to least economical method of achieving performance analysis which is the main objective of this paper. The efficiency of PV module is analyzed from I-V and P-V characteristics for this standalone solar pv system by changing radiation and temperature parameters. This paper mainly emphases on comparison of the testing results and simulation results for different radiation levels.

Developed Algorithm of Maximum Power Tracking for Stand-Alone Photovoltaic System

The rapid increase in the cost of conventional energy sources leads to the use of nonconventional energy sources. The photovoltaic (PV) is one nonconventional source that is safe, reliable, and environmentally healthy. However, the PV system is expensive and needs a large area to operate. To solve these disadvantages, it is necessary to operate at the maximum power point (MPP) of the array. This article presents a new maximum power tracking algorithm based on the incremental conductance algorithm, which successfully operates even in cases of rapidly changing atmospheric conditions. The developed algorithm depends on the relationship between the load line and the tangent line angles of the I-V characteristic curve. A simulation program was designed to investigate the performance of the developed algorithm using mathematical models for the different system components. The simulation led to a good realization of the algorithm.

CO 2 reduction potential through non-conventional energy sources in India

India will require increasingly higher energy inputs for future industrial and economic development. Overall growth of energy consumption will result in substantially higher emissions of CO 2. We present emission rates of CO 2 based on India's actual fuel consumption. It is estimated that use of non-conventional energy sources could reduce India's energy-related CO 2 emissions by 11.8% below 1988–1989 levels by the year 2005–2006.
