Abstract: This project work depicts the performance analysis of a renewable energy based hybrid power system for improving power quality because optimal utilization of primary energy sources will increase the level of supply reliability. In this project we are going to design and simulate the power system containing more than two conventional energy forms i.e. solar, wind, diesel, fuel energy are combined together for the economic operation of energy generation. By using various graphs, we can analyse that the power output of new hybrid model is higher and more efficient than the power output of the wind/PV hybrid model. Due to variation in output power of solar panel, wind turbine and fuel cell, Diesel engine is also coupled to ensure reliable supply under all conditions. Regenerative cycle of fuel cell helps to dump excess energy from DC bus. The results show that the proposed hybrid power system can effectively manage the optimal utilization of primary energy sources and improves the power quality in an islanding as well as grid connected mode.
