摘　　要：针对微网的运行特性以及用户对微网的影响,构建包含需求侧响应的微网经济优化调度模型。以需求侧负荷中的可转移负荷为主要研究对象,从用户的用电需求以及微网经济效益与环境效益出发,结合分时电价,对不同时段负荷的转入转出情况进行分析。对比负荷转移前后各微源的调度情况,分析负荷转移对于综合成本的影响。以不提高环境成本为前提,采用人群搜索算法对调度模型进行求解。算例表明微网经济优化调度中考虑需求侧响应,能够"削峰填谷",提高微源利用率,降低微网运行费用。According to the operation characteristics and the influence of users on the microgrid,an economical scheduling model including demand side response is proposed. With shifting load as the research object the proposed method analyses the load from or to the microgrid during different periods at time-of-use price,considering both the electric power demand of users and the economic and environmental benefit of the microgrid. By comparing the micro-source schedules before and after load shifting,the influence of load shifting on the comprehensive cost is analysed. On the premise of not raising the cost of environment,seeker optimization algorithm（SOA）is used to solve the scheduling model. A numerical example shows that considering the demand side response,the economical scheduling can keep a balance between peak and valley demands,improve the utilization rate of micro resources,and reduce the opera tion cost.
