Real time supervision for a hybrid renewable power system emulator

•A real time photovoltaic simulator is designed, developed and implemented.•A wind turbine real time physical simulator is conceived and fulfilled.•The two simulators are integrated and connected together for the hybridization of the two sources with batteries combination.•A significant supervision strategy of the hybrid power system is elaborated.•Tests are conducted and hybrid system performances are assessed.

This paper is focused on the design and the implementation of a hybrid PV-wind power system with batteries. It aims to emulate the behavior of a hybrid power system in order to face load consumption variations. Final system includes relevant contributions such as quality of emulator (a large number of parameters are considered); capacity to study various impacts simultaneously, a fast dynamic and a set of experimental tests that have been achieved and validated with a test bench. Moreover, a relevant supervision strategy based on currents control and batteries State Of Charge (SOC) estimation has been successfully performed despite simplicity of converter controls.
