摘要
随着共享储能的推广,能源信息的流动与共享得到进一步发展,为促进能源管理和提升利用效率,提出一种基于共享储能和需求响应的微网联盟两阶段优化调度策略.首先,建立多微网联盟-共享储能系统运行框架,并基于综合贡献度对微网利益分配过程进行建模;其次,建立两阶段优化调度模型,第一阶段以多微网联盟-共享储能系统净收益最大为目标,第二阶段考虑用户的需求响应,求解耗能用户的最低购能费用;再次,利用求解器对两阶段模型分别进行求解,得到多微网系统的分时能源价格、各微网设备的运行状态、需求响应后负荷和各微网利益;最后,设置4个方案作为算例,验证所提优化策略在提高各微网收益和激励用户需求响应的有效性.
Abstract
With the promotion of shared energy storage,the flow and sharing of energy information have been further developed.In order to promote energy management and improve utilization efficiency,a two-stage optimal scheduling strategy of microgrid alliance is proposed based on shared energy storage and demand response.Firstly,the operation framework of multi-microgrid alliance and shared energy storage system is established,and the benefit distribution process of microgrid is modeled based on the comprehensive contribution degree.Secondly,a two-stage optimal scheduling model is established.In the first stage,the goal is to maximize the net income of multi-micro network alliance and shared energy storage system;In the second stage,the minimum energy purchase cost of energy consuming users is solved by considering the demand response of users.Thirdly,the two-stage model is solved by the solver,and the time-sharing energy price of the multi-microgrid system,the running state of each microgrid equipment,the after-load of demand response and the benefits of each microgrid are obtained.Finally,four schemes are set up as examples to verify the effectiveness of the optimization strategy in improving the benefits of each microgrid and stimulating user demand response.
