考虑负荷响应的微电网容量优化配置

Optimal Allocation of Micro Grid Capacity Considering Load Response

微电网可以有效地利用可再生能源发电,具有很好的环保性,但是建设和运维成本很高。根据负荷需求功率和新能源发电功率的实时对比,设计了一种实时电价负荷响应,将负荷响应引入微电网。然后充分考虑了微电网建设运维的成本、收益和运行工况,搭建了比较贴合实际的微电网容量优化配置模型。通过算例仿真优化分析得出,负荷响应减小了负荷需求功率和新能源发电功率在时序上的差异,进而减少了各微源的配置数量,提高了微电网的经济性,同时也减少了用户的购电费用。

Microgrid can effectively use renewable energy for power generation,which is environmentally friendly,but has a large construction and operation cost.According to the real-time comparison of load demand power and new energy power generation,a real-time electricity price load response is designed,and the load response is introduced into the micro grid.Then,the cost,benefit and operating conditions of micro grid construction and operation are fully considered,and a practical micro grid capacity optimization configuration model is built.The simulation optimization analysis of the example shows that the load response reduces the difference in time sequence between the load demand power and the new energy power generation,thereby reducing the number of micro sources,improving the economy of the micro grid,and reducing the power purchase cost of users.
