Standalone wind energy conversion system using OPAL-RT real-time HIL/RCP laboratory

This paper presents a control strategy for a standalone wind energy conversion system. A Dynamometer based wind turbine emulator is connected to a permanent magnet synchronous generator, whose output is fed to a rectifier. The bidirectional converter placed between battery and dc-link voltage, is used to charge/discharge the battery according to the generated power and to keep dc link voltage constant. The single phase inverter controls the load voltage under various wind condition. The control system includes a voltage/current controller for the battery and voltage controller for the load side. The proposed system is experimentally tested using OPAL-RT real time Hardware-in-Loop system.
