摘要：

随着风电渗透率的不断增大，风电功率的波动性和不确定性给电力系统的安全稳定运行带来极大的挑战，特别是为保证系统功率平衡，需要更多的快速响应备用容量。为满足系统对备用容量不断增长的需求，提出风电参与系统调度并提供备用容量。基于场景分析建立两阶段风电柔性调度模型，用来确定常规机组及风电场提供调度计划出力及备用容量最优策略，以应对风电功率预测误差及其不确定性。在IEEE RTS-96系统中进行仿真，结果表明所提模型及方法可显著降低系统总运行成本及风险值，能有效应对风电的波动性及不确定性，实现更安全的含大规模风电并网系统调度运行。

Abstract: With the increasing penetration of wind power, the fluctuation and uncertainty of wind power bring great challenges to the safe and stable operation of power system, especially in order to ensure the power balance of the system, more rapid response reserve capacity is needed. In order to meet the increasing demand for reserve capacity of the system, it is proposed that wind power be involved in system scheduling and provide reserve capacity. Based on scenario analysis, a two-stage flexible wind power dispatching model is established to determine the optimal strategy of dispatching plan output and reserve capacity for conventional units and wind farms to cope with wind power forecasting errors and uncertainties. The simulation results in the IEEE RTS-96 system show that the proposed model and method can significantly reduce the total operation cost and risk of the system, effectively deal with the fluctuation and uncertainty of wind power, and achieve a safer dispatching operation of power system with large-scale wind power integration.
