摘要
风电集群(WFC)合理配备混合储能系统可以降低风电出力波动对电网频率影响、在改善风电可调度性的基础上提升WFC收益。以风功率备用联合储能系统共同参与一次调频为基础,以风储系统收益最大化为目标,建立了WFC加入混合储能收益最高的优化模型,采用不易陷入局部最优的鲸鱼算法进行求解,得到WFC备用比例与混合储能最优配置方案。分析了风电备用比例对WFC最大收益以及蓄电池容量配置的影响以及混合储能对蓄电池寿命的影响,对比了WFC和单独风电场优化结果。最后,以东北某WFC作为算例,验证了所提出方法能有效提高WFC收益。
Wind power schedulability and frequency stability can be improved with wind power clusters equipped with hybrid energy storage systems.This paper is based on wind power standby and hybrid energy storage system participating in one frequency modulation.The maximization of the revenue of the wind energy cluster combined hybrid energy storage system is as the target.The whale algorithm that is not easy to fall into the local optimal solution is used to solve it,and the wind power cluster standby ratio and the optimal configuration scheme of hybrid energy storage are obtained.The impact of the wind power reserve ratio on the maximum revenue of the wind power cluster and the battery capacity configuration and the impact of hybrid energy storage on the battery life are analyzed,and the optimization results of the wind power cluster and the individual wind farm are compared.Finally,a wind power cluster in Northeast China is taken as an example to verify the effectiveness of the proposed method.
