In this research paper an energy system composed of three energy conversion devices namely, photovoltaic panels, a wind turbine, and a battery is proposed. This controller directs power to a fixed voltage DC bus. The fixed voltage bus supplies the load, while the excess power is directed to the batteries. Simulation and control of a hybrid PV-wind generator system connected to the load are presented in this paper. Every major component of the system is modeled, and then different control strategies are applied to the system. To improve the performance of the system under different environmental conditions. Maximum Power Point Tracking (MPPT) of the photovoltaic system and blade angle pitch control of wind turbines are included. © EuroJournals Publishing, Inc. 2011. © 2011 Elsevier B.V., All rights reserved.
