摘　　要：针对大规模风电并网给电力系统运行调度带来的问题,指出风电在小时级的波动性和不确定性是风电并网给系统运行带来的根本挑战,为应对该挑战,利用随机模型预测控制对含负荷响应的系统联合调度运行进行建模,并从数学上证明运行策略的全局最优性。通过算例仿真验证了负荷响应在小时级的灵活性对系统运行的经济性和风电消纳的重要作用。Aiming at the problems brought by large-scale wind power integration to the operation and dispatch of power system,it is pointed out that the hourly fluctuation and uncertainty of wind power are the fundamental challenges,for which,the stochastic model predictive control is used for the modelling of system combined dispatch and ope-ration with load response,and the global optimality of the operation strategy is verified mathematically. Case simulation verifies the importance of the flexibility of load response in hourly time scale to the economy of system operation and wind power accommodation.
