Permanent magnet synchronous generator based wind energy and DG hybrid system

This paper investigates the use of permanent magnet synchronous generators (PMSGs) for a wind energy conversion system (WECS) and a diesel engine driven generator (DG) set of a standalone hybrid system with a battery energy storage system (BESS). For voltage control at the point of common coupling (PCC) and balanced supply at terminals of DG set, a single phase D-Q theory based control algorithm is applied for the switching of voltage source converter (VSC) of BESS and the maximum power point tracking (MPPT) is achieved for WECS with an incremental conductance technique for the switching of a dc-dc boost converter. Simulation results of developed model of proposed standalone hybrid system, which is developed in MATLAB demonstrate performance of both the controllers and power quality improvement of the hybrid system.
