基于一般变权方法的直流落点选择

DC Point Election Based on Variable Weight Method

直流落点选择是一个典型的多目标决策问题。选取静态电压稳定、有效短路比、系统有功功率损耗作为该多目标决策问题的三个指标。并运用一般变权原理来求解这一问题。相对于线性加权法和平方和加权法具有较好的均衡性,更符合人的决策思维。

The DC point selection is a typical multi-objective decision problem. This article selects the static voltage sta- bility, effective short-circuit ratio, the system active power loss as the three indicators of multi-objective decision problem.And using general variable weight principle to solve the problem. Compared with the linear weighted method and the weighted sum of squares method has a good balance, more in line with the thinking of people.
