26. Energy Flow Management in Standalone Hybrid Electric Generation System

The work presented is a contribution on power management of standalone hybrid electric generation system based on renewable energy sources. In this system, a photovoltaic and wind turbine generators are chosen as principals sources. A diesel generator is used as secondary source. A pack of batteries is used for stocking a surplus energy. A parallel DC bus collection of power is chosen for distribution system. Each source is connected via power converter. The models of major components included in the installation are presented. Based on these models, the proposed power management algorithm of the autonomous hybrid system is developed. For validation of the proposed algorithm, simulation results of the whole system are presented.
