Dynamic Virtual Power Plants Directly Participate in Secondary Frequency Regulation of the Power Grid
A new secondary frequency regulation control strategy has been proposed,which utilizes renewable energy sources(RES)to directly participate in secondary frequency regulation(SFC)in a dynamic virtual power plant(DVPP).Virtual synchronous generators participate in secondary frequency regulation in the same way as traditional synchronous generators,meeting the same specifications in terms of control and contract.In dynamic virtual power plants,internal real-time scheduling needs to be considered to determine the active power injection amount for each renewable energy unit unit,in order to provide support for the secondary frequency.The performance of the secondary frequency regulation strategy was verified through simulation studies of two zone benchmarks for wind farms and traditional synchronous generators.
