摘　　要：与传统电力工业环境相比,市场环境下的输电规划面临的电源建设和需求变化因素更不确定。为了使未来的输电网具有更好的适应性,提出的输电规划模型不仅同时计及了系统静态和动态的安全风险,还考虑了注入功率的不确定性。对该模型给出了基于蒙特卡罗仿真和“先放松约束,再逐条扩展线路”的求解方法,仿真结果验证了其可行性。Transmission system planning in the electricity market environment has to be confronted with much more uncertain factors, such as the locations and capacities of new power plants, and the electric power demand. In order to ensure a flexible transmission system, this paper extends the transmission planning model, which considers both static security risk and dynamic security risk to deal with uncertain injection power at the buses. A global optimization framework is developed to resolve the problems caused by the multi-object mathematical model and uncertain power injections. The resolving method based on Monte Carlo simulation and the optimal strategy of relaxing bindings first then expanding lines one by one is given. A numerical example is presented to illustrate the validity of the method.
