Abstract

Renewable power sources are the best way to reduce the effect of green house gases and thereby global warming. Among them solar power may be seen as the most reliable due to its availability. But the Solar PV system is expensive. So the main objective of this work is to develop a solar PV system which is cost effective without compromising on the efficiency of the system. The optimal operating point of each PV panel is different depending on the solar irradiation and temperature on the panel. In a string of panels the power of the entire string can be optimized and not on panel by panel basis. This paper focuses on power optimization tracking of individual PV panels using a single stage interleaved flyback converter. The proposed converter is having high voltage conversion ratio when compared to an ordinary buck boost converter. A detailed study conducted in this paper explains the practical and theoretical techniques for making the PV cells to work most efficiently all the time. A practical approach is made in this paper using the MATLAB atmosphere and to prove the quality of the theoretical concepts hardware results are also provided. The result proves that the efficiency of the entire system can be improved by optimizing each panel and the reduction of conversion stages helps to make the system more cost effective.

Abstract

Energy scarcity is one of the global issues in day to day life. The demand and consumption are moving head to head which ended up in considerable dependence of non renewable energy resources. The subsequent rise in the price and unavailability of non renewable energy sources aided to rely on the renewable energy resources in order to meet the power demand. Hybrid Energy System is one of the optimal techniques which can be efficiently utilizing the renewable energy resources. As the renewable energy resources depend upon the climatic condition it is difficult to rely upon a single system. In this paper wind and solar Hybrid Energy System is used. The output of the two different energy systems is fed to the modular DC-DC flyback converter in Input Parallel Output Series (IPOS) configuration. The system enjoys the full advantages of modularity like high efficiency and low cost. The flyback converters boost the input voltage from the hybrid energy system. The output of the system is verified using MATLAB/Simulink environment. The stability of the system is also assured due to modularity. The conventional complex powers electronic circuit can be reduced to certain extend. The system efficiency can further improved by using more number of flyback modules and modern control techniques.
