摘要:
如何引导海量分散分布的负荷侧资源参与电网调控运行成为电力系统面临的新挑战,然而目前对于海量异构负荷的协同控制方法尚缺少深入研究。文章提出了一种基于柔性负荷可控裕度的异构负荷集群控制方法。首先,对空调负荷、电动汽车充电负荷、分布式储能建立广义储能的聚合模型。其次,在聚合商-负荷设备层面,针对多类型负荷的异构特性,提出了一种基于可控裕度指标的状态序列化控制策略;在调度中心-聚合商层面,建立了日前-日内的调峰优化模型。在日前阶段,考虑了常规机组的启停计划、电动汽车充电计划和空调的中断计划,建立了以日前系统运行经济性最优为目标的调度模型;在日内阶段,聚合商中的分布式储能进一步应对风电和负荷预测的不确定性。最后,进行了算例仿真,在实现了系统削峰填谷的同时降低了系统运行成本,验证了所提控制策略和调峰优化方法的可行性与有效性。
