摘　　要：提出了一种新的大规模风电并网后日前发电计划和旋转备用决策模型。利用风电和负荷2种随机因素的概率密度函数估算系统的停电损失和弃风损失,并将它们作为风险成本计入发电成本目标函数中,在充分满足机组爬坡和系统安全等约束的前提下,同时求解每台常规机组的日前出力和正负旋转备用量。采用优先列表法和基于最小边际成本法的经济调度算法对模型进行求解。算例分析结果表明,所提模型和方法是有效的。A day-ahead generation scheduling and spinning reserve decision-making model is proposed for power system with large-scale wind power. The power outage loss and wind curtailment loss of system are estimated with the probability density functions of random wind power and power loads,which,as the risk cost,are integrated into the objective function of generation cost. The day-ahead generation schedule of each conventional unit and the up/down spinning reserve capacity are calculated with the constraints of unit ramp rate and system security. The priority list method and the economic dispatch algorithm based on the minimum marginal cost are adopted to solve the model. Results of case analysis show that,the proposed model and method are effective.
