Abstract
In order to improve the speed of reliability evaluation for composite grid,this paper proposed a method of reliability evaluation in composite power system based on estimation of distribution algorithm and intelligent storage.This method improves performance of traditional reliability evaluation methods in the stage of sampling and state evaluation.In the stage of sampling,the quality of the population was improved and state space was quickly pruned by the improved estimation of distribution algorithm.The goal of reducing variance can be realized by sampling in the pruned state space.In the stage of state evaluation,intelligent storage technology based on double across linker can speed up states exploration and avoid repeatedly calling optimal power flow for the same state.Finally,this method was tested in IEEE RTS 79.The result shows this method is not only efficient in computation but also more accurate than important sampling and intelligent state space pruning based on genetic algorithm.This method is proved to be reliable and effective by the example simulation.关键词
