HOMER(Hybrid Optimization Model for Electric Renewable，可再生能源互补发电优化建模)。HOMER是一个计算机模型，它简化了离网和并网对于远程的、独立的和分布式发电系统的评估选择的任务。HOMER优化和灵敏度分析算法，可以用来评估系统的经济性和技术选择的可行性，以及考虑技术成本的变化和能源资源的可用性。(HOMER (Hybrid Optimization Model for Electric Renewable, renewable energy and solar power generation optimization modeling). HOMER is a computer model that simplifies the task of off-grid and grid for remote, stand-alone and distributed generation systems to assess choice. HOMER optimization and sensitivity analysis algorithms can be used to select the feasibility of economic and technical assessment of the system, and to consider changes in the availability of technology costs and energy resources.)
