摘 要: 为了解决传统的输电系统面对发电、输电以及负荷的不确定因素的增加无法提出可靠的规划方案的问题,提出了基于概率潮流的机会约束规划方法,综合考虑节点负荷值、发电机出力等不确定性因素,是一类随机优化方法。给出了基于蒙特卡洛仿真的验证方法和基于遗传算法的求解方法,并以一个简单算例验证了该方法的可行性。

Abstract: In order to solve the problem that for the traditional power transmission system, it isn’t able to give reliable planning schemes to face the increase of uncertainties such as power generation, power transmission and load. This paper proposed a chance-constrained programming method based on probabilistic load flow, in overall consideration of uncertainty factors such as node load values, the generator output. This is a kind of stochastic optimization method. This paper gave the verification method based on Monte Carlo simulation and the solving method based on genetic algorithm. A simple numerical example illustrates the feasibility of this method.
