摘要

建立了以目标函数为配电网建设的投资费用、配电网网损费用和运行维护费用综合最优的混合非线性整数规划模型,以指导电力公司的电网建设规划方案,利用多个离散的二进制变量优化变电站、新建线路和变电站的扩建方案。考虑了分布式电源接入配电网,并以严格的数学模型保证配电网的辐射运行结构。提出用内点-分支定界法精确求解电力系统配电网扩展规划模型,结果表明该方法是一种可行的配电网扩展规划方法。

Abstract

A mixed integer non-linear programming (MINLP) model is built in this paper, which makes the construction of power distribution network as the target function, and is concerned with investment cost, power losses cost and operation cost of power distribution network, so as to guide the power grid planning for power companies. This model could use multiple discrete binary variables to optimize substation and its expansion plan, new transmission line. The accessing of distributed power sources to the distribution network is considered to maintain the radial operation structure of distribution network with the strict mathematical model. The point-branch and bound method is proposed to accurately solve the distribution network expansion planning model, which has been proved to be feasible.
