摘要
为解决输电网规划过程面临的非确定性因素问题,文章通过构建含随机变量的变参数矩阵对非确定性随机因素进行研究,并将鲁棒优化理论引入规划评价方法中。使用鲁棒对等变换手段对随机矩阵进行确定性处置,并在考虑二次调频及安全裕度的多维度边界条件的基础上进行寻优,提出了一种具有鲁棒性的输电网随机优化方法,并对方法进行了仿真模拟,验证了方法的有效性。
In order to solve the non deterministic factor problems in the transmission network planning process,the uncertain random factors by constructing the variable parameter matrix containing random variables were studied and the robust optimization theory to the planning evaluation method was introduced.Based on the multi-dimensional boundary conditions of secondary frequency regulation and safety margin,a robust method of stochastic optimization for transmission network was proposed.The methodwas simulated and the effectiveness of the method was verified.
