Abstract
The wind farm by using the direct current collection method will provide a new way for the future large-scale renewable energy power generation.Due to the fluctuation of the output power of wind power generation system will have a negative impact on the operation stability of power grid,and a power coordinated control scheme of DC parallel wind farm with energy storage system is proposed in this paper.By comprehensively considering grid demand,wind turbine state and energy storage state of energy storage system,power instructions of the DC wind turbines can be sent from control center.Through adjusting output power of the generators and the wind turbine energy storage system,the active power output of wind farms can meet the requirements of power grid in a certain range,which greatly reduces the influence of wind power fluctuation on power grid.Under the premise of meeting the simulation accuracy,the rectifier and the isolated full bridge DC/DC converter of the DC wind turbine and the super capacitor energy storage system are simplified properly.The simulation results of PSCAD/EMTDC are used to meet the requirements of the control target,and the effectiveness of the proposed control strategy is verified.关键词
