The structure and control characteristics of wind/photovoltaic/energy storage hybrid power system are comprehensively analyzed,and flexible combination control modes and single plant control modes are proposed to realize seamless switching between independent control and complementary control of the wind,photovoltaic and energy storage system.Aimed at meeting various application demands including smooth generation output,control of target tracking and frequency adjustment,an improved smooth control strategy and a coordinated strategy of binding wind power with photovoltaic power and decoupling energy storage system are proposed,with the feedback of state of charge taken into account.The proposed control mode and strategy have been applied in the national wind,photovoltaic,energy storage and transmission demonstration project,the viability and effectiveness are verified.
