摘　　要：随着新能源在电网中的渗透率越来越高,大量风电接入电网已成为制约电网频率稳定性的一个关键问题。配置储能可以提供系统的暂态频率支撑、改善风电的波动、增强风力发电的稳定性。首先,通过考虑风电场的一次调频需求,以电池运行状态为出发点,提出基于荷电状态(SOC)考虑充放电状态量系数控制策略,并建立电池使用寿命模型。在此基础上,以风储系统年综合成本之和最小为总目标,构建计及荷电状态和电池使用寿命的储能系统功率和容量优化配置模型。其次,采用蚁狮算法求解优化结果,分析综合成本、电池使用寿命和荷电状态对优化结果的影响。最后,用仿真验证了结果的有效性。As the penetration rate of new energy in the power system continues to increase,the large-scale grid connection of wind power is one of the important factors affecting the stable frequency operation of the power system.Configuring energy storage can provide transient frequency support for the system,improve wind power fluctuations,and enhance the stability of wind power generation.Firstly,by considering the primary frequency regulation requirements of wind farms and starting from the operating status of batteries,a state of charge(SOC)control strategy taking into account charge coefficient and discharge states was proposed,and a battery service life model was established.On this basis,with the overall goal of minimum sum of annual comprehensive costs of wind storage systems,a power and capacity optimization configuration model for energy storage systems was constructed that taken into account the state of charge and battery life.Secondly,the ant lion algorithm was used to solve the optimization results,and the effect of complex cost,battery life,and charge status on the optimization result was analyzed.Finally,the effectiveness of the results through simulation was validated.
