Optimization of Wind Power Heat Pump System for Rural Buildings Based on Hybrid Energy Storage
Capacity allocation optimization of hybrid energy storage systems is an important foundation for promoting clean heating from wind power in northem countryside.A two-layer optimization method 可capacity allocation for wind power heat pump hybrid energy storage system is proposed for northern rural houses.The wind power heat pump hybrid energy storage system is structured,and the load characteristics of rural houses are analyzed by cluster analysis;A two-layer capacity allocation optimization model is established.The upper layer is to optimize the equipment capacity of the system for the maximum net profit over the entire lifecycle,while the lower layer is to optimize the hourly power of each device in the system for the minimum operating cost.Through nested iterations between the two levels of the model,the optimal system capacity configuration solution was obtained.Finally,a rural residential complex in Liaoning is used as an example for validation.The results show that the optimized wind power heat pump hybrid energy storage system has a net benefit of 22.08％higher than that of the power-only storage scheme and 1410％higher than that of the heat-only storage scheme,and the utilization rate of clean energy reaches 99.27％,which takes into account the economic benefits and wind power consumption.This study achieves economic operation while performing capacity allocation,providing theoretical guidance for residential wind-power hybrid energy storage heating projects in the northern countryside.
