摘要:  从全社会成本视角出发，构建了含大规模风电的电力规划方案评估的总体框架．其中，为计及风电出力波动性的影响，针对给定的规划方案和全年时序的风电出力与负荷数据，通过内嵌机组组合优化模型、计及静态和动态安全约束的经济调度模型(动态安全域边界的超平面形式可使动态安全约束处理难的问题变得十分简易)及校正性控制模型，实现系统运行过程的模拟，从而可详细评估全年每小时的系统燃料、环境、网损成本以及系统可靠性成本．再结合电源的容量成本和电网成本，则可获得方案的全社会成本，实现规划方案的全社会成本评估．最后通过示例分析验证了方法的有效性．
Abstract:  From the perspective of the total social cost，the overall framework of evaluation of power system plan-ning with large-scale wind farms was established. According to the annual chronological hourly data of wind power and load，for a given power system planning alternative，its system operation simulation was carried out，wherethe variability of wind power was considered. In the simulation process，daily-ahead(or week-ahead)unit commitment model，steady state and dynamic secutiy constraints based economic dispatch model and remedial control model were included. It was emphasized that based on the hyper-plane description of the bounary of the practical dynamic securityregion(PDSR)，the difficulty of dealing with stability constraints in the problem of solving for steady state and dy-namic secutiy constrained economic dispatch can be overcome easily. Hence the hourly fuel，environmental and net-work loss cost in the year for the given planning alternative could be calculated. These costs were to be combined with generation capacity cost，power network cost and system reliability cost，so that the total social cost of the alterna-tive could be determined. Therefore the evaluation of the total social cost of an alternative was achieved. Finally，the proposed method was validated by means of the case studied.
