辅助风电场参与初期黑启动时储能电站容量配置策略

摘要

A new strategy of capacity configuration of energy storage system is proposed for making full use of wind power in the preliminary black start (BS).First,maximum power fluctuation which the preliminary restoration system could balance is got,which is regarded as the limitation objective of the wind power output.Then,the limitation objective is treated as the main evidence for determining the power of the energy storage station and the limitation objective and the start-up time of the typical thermal units auxiliary system are regarded as the main evidence of determining the capacity of energy storage station,which ensure that wind power output fluctuation is limited in the limitation objective during the period when the energy storage station plays a role in balancing fluctuation.At last,wind-storage model is established in PSCAD/EMTDC and it is verified that the configured energy storage power station could ensure the wind farm integrate into the preliminary BS safely and smoothly by simulation.The proposed capacity configuration strategy of energy storage system is indicated for other new energies which would be integrated into the BS.%为了让风电参与初期黑启动,提出了新的储能配置策略.首先求取了初期恢复系统所能平抑的最大功率波动,将此作为风电输出功率的限幅目标.然后将限幅目标作为确定储能电站功率的主要依据,将限幅目标和典型火电机组辅机的启动时间作为确定储能电站容量的主要依据,从而确保在储能电站发挥平抑作用的时间长度内,风电场的输出功率波动值限定在限幅目标内.最后用PSCAD/EMTDC搭建了风储模型,通过仿真验证了配置的储能电站能够使风电场安全平稳地参与初期黑启动.此储能电站容量配置策略同样适用于参与黑启动的其他新能源.
