For the purpose to take into account both economy and reliability of electric power network planning,this paper presents a optimal model that multi-objective function consists of the minimum invest cost of the supplier's and the minimum risk cost of load interruption based on risk assessment.With analyzing the constraint degrees of each objective function by the rough set theory,so that it can set each objective functions' weight in the optimal model.Consequently,the improved hybird genetic simulated anneal...
0引言多目标电网规划(multi-objective electric power network planning)是在某些约束条件下,同时考虑—两个及两个以上目标(指标)的电网规划问题,该问题是一个复杂的优化问题,具有多目标性、时变性、离散性、非线性及约束条件复杂等特点。电力网络规划的目的是力求在规划期末
