The traditional deterministic 以及求解算法的有效性。 economic dispatch method can’t meet the safety operation 关键词：风力发电；风电场；概率预测；动态经济调度；机 requirement of power system anymore. Based on the wind 会约束规划；运行风险；序列运算 power probabilistic forecasting, a stochastic model for dynamic economic dispatch was proposed based on chance-constrained 0 引言 programming. The operation risk constraints and the uncertainty of wind power were considered in the model. Thus, 与传统化石类能源相比，风力发电具有无能源 the weak link and potential risk of system operating was 消耗、无排放和无污染的特点。为保障能源安全、 displayed directly, and a theoretical reference to weigh the fuel 推动环境保护，中国积极鼓励风电的大规模开发利 cost and operating risk was presented for operator
