摘要:
      区域供电线路故障会使部分线路出现短时拥塞,同时区域内重要负荷供电不足,导致大量切机和切负荷。针对这一问题,提出一种应对区域供电线路故障的多功能复合储能优化配置方法。该配置方法考虑了各发电单元在线路故障发生后的响应时间,优化配置功率型储能和切除部分非关键性负荷以缓解线路短时拥塞。考虑重要负荷在故障检修期间的供电需求指标,在已有功率型储能基础上,协调优化配置能量型储能以保障区内重要负荷供电。最后,以复合储能整体投资费用最小为优化目标,结合实际电力系统算例进行了仿真,对影响配置结果的关键参数进行了灵敏度计算,深入分析了复合储能优化配置的相关原理,验证了所提模型和方法的正确性。
Abstract:
      Regional power line faults may cause short-time congestion on other lines and power supply shortage of the important load in the region, which may result in a large number of generator tripping and load shedding. To deal with the problem, a configuation optimization method of multifunctional hybrid energy storage for regional power line faults is proposed. The proposed method considers the response time of each power source unit, configures power-type energy storage optimally and cuts some non-critical load to relieve the short-time power grid congestion. The power supply demand index of the important loads in the corrective maintenance period is considered, and energy-type energy storage is configured optimally to guarantee the power supply of important loads in the region based on the configured power-type energy storage. Finally, the total investment of the hybrid energy storage is selected as the objective, the case studies are performed in a real power system, the sensitivity analysis of some key parameters for the configuration solution is given and the correctness of the proposed model and method is validated.
