Design and Simulation Analysis of Electric Heating Co-supply System in Remote Areas

我国西部偏远地区自然环境恶劣,居民居住分散,用电难、用热难等问题亟需解决。针对上述问题,考虑偏远地区负荷的特殊性,结合地区气候、环境以及资源特点,设计了3种具适用于高海拔偏远地区的电热能源供给系统,搭建了各类综合能源系统的仿真模型,设计了分层优化配置算法,在HOMER环境下进行了优化配置仿真,求解了相同负荷和环境条件下3种能源供给系统的优化配置方案。3种能源供给系统均包含光伏、储能、相变储热以及电热转换装置,可代表高海拔偏远地区清洁用能的典型特征。通过对3种能源供给系统优化配置方案的仿真分析,可以为偏远地区清洁能源供给设计规划提供必要的参考依据。

In the western remote areas of China,the natural environment is harsh,the residents live scattered,and the problems such as difficult to use electricity and heat need to be solved.In view of the above problems,considering the particularity of load in remote areas,combined with regional climate,environment and resource characteristics,three kinds of electric heating energy supply systems suitable for remote areas at high altitudes were designed,simulation models of various comprehensive energy systems were built,hierarchical optimization allocation algorithm was designed,and optimization allocation simulation was carried out under HOMER environment.The optimal configuration scheme of three energy supply systems under the same load and environmental conditions is solved.The three energy supply systems all contain photovoltaic,energy storage,phase-change heat storage and electrothermal conversion devices,which can represent the typical characteristics of clean energy use in remote areas at high altitudes.Through the simulation analysis of the optimal configuration scheme of three energy supply systems,it can provide the necessary reference for the design and planning of clean energy supply in remote areas.
