摘要(Abstract)：

风电功率预测存在误差,增加了电力系统运行调度的困难,影响系统风电消纳,降低系统运行的经济性。为了提高系统风电消纳能力,考虑风电功率预测误差,结合需求响应特点,从日前、日内和实时构建了电力系统需求响应多时间尺度优化调度模型。分析居民用户需求对电价的响应,构造日前价格型需求响应的初调度策略,并在日内根据风电功率预测偏差进行电价调整后的价格型需求响应再调度。分析工业用户和商业用户的调度补偿策略,以电网运行费用最低为目标,考虑平衡风电功率实时预测误差,建立激励型需求响应的实时调度优化模型,以提高系统风电消纳能力,降低系统弃风量。算例分析表明:所提出的优化调度策略能够较好地平衡风电功率预测误差,增加系统风电消纳量,节约系统运行成本,保证用户用电的自主性,最小化需求响应调度对其的影响。
