摘　　要：随着风电并网容量的增加,电网出现了一定程度的弃风。调度模式直接影响电网接纳风电的能力。本文分别构建了综合考虑系统运行成本和弃风量最小的调度模式、系统运行成本最小的调度模式以及弃风量最小调度模式的模式。提出利用分层优化的思想求解,外层采用基于分段断点的动态规划法安排机组的启停,内层采用多智能体粒子群算法求解系统运行的相关指标。通过算例计算,从调度经济性角度分析不同调度模式下电网最佳风电出力接纳水平。With the increasing of wind power integrated power system, the grid has begun to abandon wind energy to a certain extent. Dispatching models will directly impact the capability of accommodating wind power. This paper proposes three dispatching models for considering minimum system operation cost and abandoning wind energy ,min- imum system operation cost and minimum abandoning wind energy. In order to solve the models, hierarchical opti- mization algorithm is proposed. The outside algorithm is dynamic programming algorithm based on segmentation breakpoint and the inside algorithm is Muti-Intelligent-Agent System particle swarm optimization （MIAS- PSO）. By testing a simulation example, the optimal wind power integrated grid is obtained based on the dispatching economy.
