摘　　要：输电网规划中不可避免地会涉及大量规划人员控制或预料之外的不确定性因素,合理的规划方法是将处理不确定性因素的方法与最优方法有机结合。针对电力市场环境下输电网规划面临大量不确定因素的影响,结合逐步扩展法,提出了采用半不变量法处理输电网规划中的不确定性因素。改进的"19节点系统"验证了所提方法的可行性。计算结果表明:所提方法的特点是计算速度快、且不存在不收敛问题。Transmission network planning inevitably involves a large number of unexpected uncertainties exceed planners＇ control or expectations.Therefore,a reasonable method of planning is an organic combining of handling uncertain factors with the optimal method.Because the transmission network is affected by uncertain factors in electricity market environment,the cumulant method combining with heuristic successively expanding method is proposed to deal with uncertain factors.The method was proved feasible through the modified 19-bus system.Also,the characteristics of the proposed method are fast calculation,and does not exist convergence problems.
