摘要: 主动配电网(active distribution network,ADN)能够综合运用需求响应和协调优化管理两大手段,通过源荷协调互动,最大限度上实现分布式电源的高效消纳和系统运行的安全经济。文章提出了计及需求响应的主动配电网双层优化调度模型。其中电价协调层以价格型需求响应为核心,通过调整日前实时电价优化各时段负荷需求;可调度单元控制层基于负荷需求,在计及ADN内部不确定性因素对系统安全影响的前提下,以运行成本最低为目标制定系统运行计划。调度模型双层之间基于信息双向流动实现协调互动,为提高求解效率,提出了将智能优化算法和传统优化算法相结合的求解策略。算例结果表明,所建模型能够保障系统安全裕度、降低配网运行成本、提高用户满意度和减小负荷峰谷差。

Abstract: Active distribution network can promote effective consumption of distributed generation and ensure safe and economic operation of the system by taking advantage of demand response and coordinated optimization to guide source-load coordination. Considering the uncertainties of system, a bi-level optimal dispatch model of active distribution network is proposed. The price coordination layer, taking the price-type demand response as the core, optimizes the load demand by adjusting day-ahead electricity price. The schedulable unit control layer makes the operational plan of system according to load demand to minimize the operating cost considering the effect of uncertainties within active distribution network on the safety of system. The two layers exchange information with each other and achieve the coordination and interaction. A solution strategy combining intelligent optimization algorithm and traditional optimization algorithm is proposed to improve the solution efficiency. The results of the example show that the proposed model can ensure the safety of system, improve customer satisfaction, as well as reduce the system operating cost and peak-valley difference.

Key words: active distribution network, bi-level interactive dispatch optimization, demand response, sensitivity analysis
