【摘要】：需求响应的实施需要对负荷侧资源进行有效整合和合理管理,负荷聚集商作为其他电力系统参与者与需求响应资源之间的新兴中介,可参与电力系统源荷互动的实现。针对目前主网调度负荷侧资源存在障碍的问题,提出以负荷聚集商安排负荷削减合同的方式参与需求响应,上层以系统综合调度成本最低为优化目标,下层在分析主动负荷用电特性的基础上制定负荷削减合同作为负荷聚集商的调用对象,以此构建源荷互动双层优化模型进行算例仿真。结果验证了负荷聚集商的参与能降低发电机组的启停费用,在兼顾各方利益的同时有利于系统削峰填谷及经济效益最优的实现。
[Abstract]:The implementation of demand response requires the effective integration and rational management of load-side resources. As a new medium between other power system participants and demand response resources, load aggregators can participate in the realization of power system source-load interaction. In view of the obstacle of load side resources in the main network at present, it is proposed that load aggregators arrange load reduction contracts to participate in demand response, with the lowest cost of system integrated scheduling as the optimization goal in the upper layer. On the basis of analyzing the characteristics of active load consumption, the lower layer formulates the load reduction contract as the calling object of the load aggregator, and constructs a two-layer optimization model of source-load interaction for simulation. The results show that the participation of load agglomeration quotient can reduce the start and stop cost of the generator set, and it is beneficial to the system to cut the peak and fill the valley at the same time as the benefit of all parties and to realize the optimal economic benefit.
