Abstract :

This paper describes modeling and simulation of microgrid connected renewable energy based Hyid Power System (HPS) in the aspect of improving power quality. Since optimal utilization of primary energy sources will increase the level of supply reliability, a dynamic control algorithm is proposed for economic energy management. In order to meet sustained load demands during varying natural conditions, different renewable energy sources and power conditioning units are need to be integrated with each other. The paper focuses on the combination of Photo Voltaic (PV) cell, Wind Turbine (WT), Fuel Cell (FC), and Battery systems for power generation. To improve power quality of the power system, the proposal is to use DC MotorSynchronous Generator Set instead of conventionally used static Inverters. A Diesel engine is also coupled to synchronous generator as a standby prime mover to improve the reliability of the overall system during varying natural conditions like wind velocity, irradiance, temperature and etc. The proposed control algorithm acts as a idge between load fluctuations and generating capacity for managing available resources economically. The results show that the proposed hyid power system can effectively manage the optimal utilization of primary energy sources and improves the power quality in both islanding mode and as well as grid connected mode.
