摘要(Abstract):
针对分布式能源附属于不同主体带来的协调控制问题,引入多代理系统建立多微电网的能量智能协调控制策略。将风光储、燃气发电和可控负荷聚合为微电网,并在用户侧实施价格型需求响应。针对多微电网运行特征,设计了3层协调控制系统框架,并提出了区域自治和全局协同优化控制的求解过程。算例结果显示:1)所提能源协调控制策略可用于优化并网与孤岛模式下多微网优化调度。2)储能系统以经济最优模式可获取更优的经济效益,寿命最长模式则为保障储能系统平稳运行而减少经济效益。3)考虑PBDR时,系统需求负荷峰谷比显著下降,对储能系统与燃气机组的备用需求减少,为可再生能源消纳提供了更大空间。因此,所提微电网协调策略能为决策者提供可靠的决策工具。
