Power Control and Energy Management Strategy for a Stand-alone WECS
摘要
Abstract
A simple power control and energy management strategy is proposed to optimally control the power generated by the turbine and effectively manage the energy that supply to different loads for a stand-alone permanent magnet synchronous generator (PMSG)-based variable speed wind energy conversion system (WECS) consisting of a battery bank and a dump load. By simply regulating the dc bus voltage at different levels, the energy that will supply to the user's loads, charge to the battery and dissipate by the dump load can be optimally managed. Moreover, due to the energy management scheme proposed, the power control of the wind turbine can be de-coupled, which means the power control system only needs to optimally control the generated power of the turbine follow the ideal power curve and the power will be supplied to different loads from the dc bus optimally. Thus, the control system is much simpler than the existing control strategies that used for the stand-alone WECS. To verify the effectiveness of the pro-posed power control and energy management strategy, a 1.2 kW stand-alone WECS laboratory test-rig is established, the validity of the proposed strategy is verified through experi-ments.关键词
