基于非序贯蒙特卡洛模拟的电网规划方法

The Methods of Power Grid Planning Based on Non Sequential Monte Carlo

针对全球能源互联网的发展,风电、光伏等可再生能源不断并入电网,电网规模越来越大,从而使电网安全规划难度越来越大的问题,为了解决该问题,从电网高危输电线路的识别和化简等方面进行了研究。利用非序贯蒙特卡洛方法模拟IEEE14系统的多种运行方式作为实际运行数据,对高危输电线路的识别和化简模型进行了测试。结果表明,该方法能够实时识别出电网中高危输电线路,并以此实现电网的简化等功能,从而可以极大的提高电网化简后输电线路的有效监视和规划效率,应对安全事故的快速处理,从而应用于电网输电线路规划。

Aiming at the development of global energy internet,the renewable energy generation of wind,photo-electricity incorporated in the power grids continuously,the power grid scale becoming much bigger,and the power system planning becoming more and more difficult,so the problems of high dangerous transmission lines recognition and reduction have been studied.The many operation modes of the IEEE14 bus system are made by using non sequential monte carlo as the real operation to test the power grids reduction methods.Experimental results show that the method can verify the high dangerous transmission lines and reduce the power grid,and can improve efficiency in the transmission line power active monitored to handle the safety accident quickly.And the result can be applied to the transmission line planning.
