摘　　要：传统输电网规划方案由于没有考虑网络中各线路的负载运行水平,得到的最小费用方案会导致部分线路负载率偏高。文中的新规划模型将线路投资费用和网络剩余输电容量作为目标函数,同时考虑优化线路负载率的分布,用以求取最少投资下具有最大网络剩余输电容量的规划方案。结合混沌变量的随机遍历特性,将混沌优化算法应用于输电网非线性混合整数规划模型的优化求解。算例表明方法的正确性和有效性。In the conventional transmission network planning, the loading levels of different transmission lines are not considered. This may cause some transmission lines with unexpected high level loading. To solve the problem, a novel planning model is presented to minimize costs while maximize spare capacity. Given the stochastic and ergodic characteristics of fuzzy variables, a chaos optimization algorithm is introduced to solve the planning problem. Two system studies verify the proposed method.
