Power Management Strategy for Solar Stand-alone Hybrid Energy System

This paper presents a simulation and mathematical model of stand-alone solar-wind-diesel based (HES). A power management system is designed for multiple energy resources in a stand-alone hybrid energy system. Both Solar photovoltaic and wind energy conversion system consists maximum power point tracking (MPPT), voltage regulatio basic power electronic interfaces. An additional diesel generator is included to support and improve the reliability of stand when renewable energy sources are not available. A power management strategy is introduced to distribute the ge among resistive load banks. The frequency regulation is developed with conventional phase locked loop (PLL) system. The power management algorithm was applied in Matlab the results. Keywords—Solar photovoltaic, wind en hybrid energy system, power management, frequency and voltage regulation.
