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.
