考虑内部多地区间交互协作的复杂省级电力市场交易优化决策

为实现电力市场大范围资源优化配置，提出了一种考虑内部多地区间交互协作的省级电力市场交易优化决策方法。首先介绍了市场交易架构和机制，同时以全省社会福利和跨地区交易电量最大化为出清目标，其中社会福利计及了线路的输配电成本。然后，优化决策中考虑了全省各地区内部的电网安全约束、供热机组运行约束和交易决策约束等多约束条件，并对地区间电力联络线的运行约束进行了建模。最后，以京津唐实际电网为例，验证了所构建模型的有效性。

Transaction Optimization Decision in Complex Provincial Electricity Market Considering Inter Regional Cooperation

In order to realize the optimal allocation of resources in electricity market， this paper proposes a decision-making method for transaction optimization in provincial electricity market considering the interaction and cooperation among multiple regions. Firstly， the market transaction structure and mechanism is introduced， taking the maximization of social welfare and trans-regional transacted electricity quantity as clearing objective， in which the social welfare takes into account the transmission and distribution cost of power line. Then multiple constraints such as power grid security constraints， heating unit operation constraints and transaction decision constraints are considered in the optimization decision， and the operation constraints of inter-regional power tie lines are modeled. Finally， the effectiveness of the model is verified by taking Beijing-Tianjin-Tangshan power grid as an example.
