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.
