Modeling and simulation of power flow controller in hybrid renewable energy systems

This paper deals with hybrid renewable energy generation system, applying advanced power control techniques fed by three power sources namely: wind power, solar power, and storage battery which is not connected to a commercial power system. Considerable effort was put into the development of active-reactive power control. Phase locked loop (PLL) is a phase synchronization technique through which the active power can be controlled. As the system uses only natural energy sources there is no cause for polluting the surrounding environment. The above system can be used for supplying power on isolated islands and in rural locations without any dependence on the commercial power system. The system is also flexible, so different power sources can be interconnected anywhere on the system there by increasing the production of power.
