储能参与电力系统快速调频的需求评估方法
|
摘要
随着特高压直流建设和可再生能源发展,直流闭锁故障对电力系统快速调频提出了挑战。针对储能技术改善电力系统频率稳定性,提出了一种储能参与系统快速调频的需求评估方法。首先提出了电力系统快速调频的瓶颈评估指标和瓶颈场景分析方法,为储能容量配置提供了场景基础;接着又提出了基于瓶颈边界场景的储能容量优化配置方法,以最小化储能容量配置成本消除电力系统快速调频的瓶颈场景;最后基于江苏电网实际数据进行了算例分析,结果验证了所提出的需求评估方法的有效性。
With UHVDC construction and renewable energy development, DC blocking faults bring challenge to fast frequency regulation of power system. To improve frequency stability of power system with energy storage technology, a demand assessment method is proposed for energy storage to participate in fast frequency regulation of power system. Firstly, bottleneck evaluation index and bottleneck scenario analysis method of fast frequency regulation are proposed to acquire scenario basis for capacity configuration of energy storage. Then an optimal configuration method on capacity of energy storage is proposed based on bottleneck boundary scenario, which eliminates bottleneck scenarios with the minimum cost of capacity configuration of energy storage. Finally, the effectiveness of the proposed method is verified via case studies based on actual data of Jiangsu grid.
