摘要(Abstract)：

针对风电、光伏等大规模可再生能源并网后电力系统调峰能力不足的问题,在分析调峰补偿与调峰分摊的基础上,考虑火电机组调峰主动性约束,提出一种风光水火储多能系统互补协调优化调度策略。考虑多能系统电源结构复杂,涉及变量及约束条件较多,因此采用分层优化调度方案。上层模型以净负荷波动最小和储能系统运行收益最大为优化目标,旨在充分利用储能装置削峰填谷特性,降低负荷峰谷差,提高可再生能源的消纳空间;下层模型以火电机组运行成本最小和可再生能源弃电量最小为优化目标,考虑调峰主动性约束,旨在充分发挥火电机组深度调峰能力,优化可再生能源消纳能力和火电机组经济运行。基于分解协调思想,实现上、下层问题的协调和下层问题的交替迭代求解。最后,以改进的IEEE30节点系统为例,进行多种场景的仿真计算分析,结果表明所提策略能有效提升系统可再生能源的消纳能力和系统运行的经济性,验证了该模型的有效性。
