摘要
为有效减少发电侧与用电侧之间的电能不平衡以及相关独立微电网成本过大的问题,对风光储微电网进行经济优化研究,采用转移负荷时域对负荷进行调度规划。提出一种基于需求侧响应(demand response,DR)的风光储微电网经济优化方法,通过比较DR优化前后结果,确定风光储微电网最佳配置。在需求侧响应线性规划的框架下,对风光储微电网各组件进行数学建模。建模仿真结果表明:DR优化后的风光储微电网模型减少了所需光伏、风力机、储能及并网逆变器的组件数量,总净现成本得到控制;DR优化后减少了负荷峰谷差,使电能趋于平衡,具有显著的实用价值。
In order to effectively reduce energy imbalance between the power generation side and the power consumption side,as well as the problem of excessive costs related to independent microgrids,this paper carries out economic optimization research on the solar energy storage microgrid and studies load scheduling planning using the transfer load time domain method.It proposes an economic optimization method for wind and solar storage microgrids using demand response(DR).By comparing the results before and after DR optimization,it determines the optimal configuration of wind and solar storage microgrids.Under the framework of demand side response linear programming,mathematical modeling is conducted on various components of the solar energy storage microgrid.The modeling and simulation results show that the optimized wind and solar energy storage microgrid model by DR reduces the number of components required for photovoltaics,wind turbines,energy storage,and grid-connected inverters,and the total net cash cost is controlled.The DR optimized model reduces the peak valley load difference,making the electricity tend to balance,and has significant practical value.
