Research on Optimized Capacity Allocation of Wind-Solar-Storage Complementary Power Generation System Based on HOMER Simulation

以系统总成本最小为目标函数,基于可再生能源发电混合系统优化仿真软件(Hybrid Optimization Model for Electric Renewables,HOMER),针对某工业园区的风光资源数据和负荷情况,进行了设备成本和参数设定。在获得的配置方案中,对比分析了并网型风光储、风光互补以及风储、光储发电系统的优化配置方案,分析其弃电率和经济性,验证了风光储系统的优越性,最终得到并网型风光储互补发电系统总净现成本最小的配置,并对其各设备的年发电量、系统可靠性及经济性进行了分析,可为可再生能源多能互补微电网风光储系统容量优化配置的研究提供参考。

This paper takes the minimum total cost of the system as the objective function,based on the optimization simulation software HOMER(Hybrid Optimization Model for Electric Renewables)for the hybrid system of renewable energy power generation,the equipment cost and parameters are set according to the data and load of a certain industrial park.Among the obtained configuration schemes,the optimized configuration schemes of grid-connected wind-solar-storage,wind-solar complementation,wind-storage,and solar-storage power generation systems are compared and analyzed,and their power rejection rate and economy are analyzed,the advantages of the wind-solar-storage system are verified,and finally the configuration with the lowest total net cash cost of the grid-connected wind-solar-storage complementary power generation system is obtained.The annual power generation,system reliability and economy of each equipment are analyzed,which can provide a reference for the research on capacity optimization of renewable energy multi-energy complementary micro-grid wind-solar-storage system.
