摘　　要：用户端多种供能方式联合调度将是未来智能电网需求侧管理的重要组成部分。针对配电网与热力管网运行管理信息交换不同时的现状,分别采用"以热定电"和"以电定热"的配网调度策略模拟热力管网优先、配电网优先的管理方案;以联合配电网与热力管网同时调度的"经济最优"策略。分别建立供热优先、供电优先和综合经济最优的配网供能调度模型,以南方某地区夏季典型日调度结果为例分别比较三者的经济性,分析算例结果表明,所提出的"经济最优"模型能在满足用户不间断供能需求下,经济性最优。Muhi-dispatch based on variety ways of client energy-supplying is an important part of demand-side management in the future. Focused on the non-simultaneous of the management decision information exchange be- tween the local power grid and heating network, we built Heating Priority and Power Priority policy to preferentially do the dispatch to make heat or power balanced. Simultaneously, we built an Economical policy to dispatch the power and heat contemporary. Based on those policies, we made distribution network dispatch models separately. Comparing the dispatch cost of each models on the load and weather data of an area in the south China, the paper confirms the truth of the model based on the third policy cost the least.
