摘　　要：区域中长期电力市场是区域电力市场的主要研究对象之一,为提高合约电量利用率,降低交易电量因传输通道未被充分利用或线路过载而被削减的可能性,基于目前的区域中长期合约定价机制,以“点对点”交易方式为基础,结合电网各类分布因子,以区域中长期合约电量线损量最小为目标函数,对区域中长期合约电量传输路径进行优化,并将新的优化路径作为省内现货出清的约束条件,研究区域中长期合约电量路径优化对省内现货出清结果的影响,以及对降低省内线路潮流量的效果。为此,分别建立省内现货出清模型和区域中长期路径优化模型,找到两者的约束耦合关系。最后,利用IEEE 30节点系统进行算例仿真,分析区域中长期合约路径优化对降低其合约能量损耗和降低省内现货出清线路潮流的可能性。The regional medium and long term power market is one of the main research objects of the regional power market.In order to improve the utilization rate of contracted power and reduce the possibility of the traded power being cut due to under-utilization of the transmission channel or overloading of the line,based on the current pricing mechanism of the regional medium and longterm contract and the point-to-point trading method,and combining various distribution factors of the power grid,this paper optimizes the transmission path of regional medium and long term contract power with the objective function of minimizing the line loss of regional medium and long term contract power.It also takes the new optimized path as the constraints for the intra-provincial spot clearing,studies the impacts of optimizing the path of regional medium and long term contract power on the results of the intra-provincial spot clearing as well as the effects of reducing the line tidal current in the province.To this end,it establishes the intra-provincial spot clearing model and the regional medium and long term path optimization model respectively to find the constraint coupling relationship between the two.Finally,the paper carries out an arithmetic simulation using the IEEE 30 node system to analyze the possibility of the regional medium-and long-term contract path optimization to reduce its contractual energy loss and to reduce the intra-provincial spot clearing line tidal current.
