摘　　要：全可再生能源系统完全依靠可再生能源满足用户用能需求,近年来成为国内外研究热点。然而,不同区域气候及地质环境差异较大,全可再生能源系统结构与性能也具有区域特征。提出一种全可再生能源系统优化配置方法,并以住宅小区为研究对象,考察全可再生能源系统在我国不同区域的运行特征与可行性。考虑生物质能、风能、光能分布差异,选取我国30个典型城市,构建住宅小区全可再生能源系统;搭建全可再生能源系统模型,并以年总费用为目标,通过遗传算法获得我国不同区域全可再生能源系统优化设计方案;分析不同区域系统的运行特征与可行性。结果表明,在我国当前能源市场条件下,我国多数地区全可再生能源系统以太阳能和生物质供能为主,太阳能供电占比超过60%,在太阳能资源丰富区可达90%左右,而风能利用有限。全可再生能源系统在大多数区域经济性良好,相比传统系统回收期低于6年。The 100% renewable energy system can satisfy energy demand totally by renewable energy,which is becoming increasing popular in studies and practical applications worldwide.However,the 100% renewable energy system in different areas would have very different structures and characteristics due to different climates and geographical features.This paper proposed a new design and optimization method for 100% renewable energy system and investigated the system coupling characteristics and performance in different areas in China.Totally 30 typical cities located in different regions are chosen according to the distribution characteristics of renewable energy and climates.A residential community is selected.The total annual cost is taken as the optimization objective to obtain the optimal design of the 100% renewable energy system in each area.The integration and operation characteristics are analyzed.Results show that under the current energy market conditions,the 100% renewable energy systems serving low-density residential communities are feasible in most regions of China.The electricity supply proportion of solar energy is more than 60% in most regions.The proportion can reach 90% in abundant solar energy area.However,the use of wind power is limited.The economic performance of the system is promising with payback periods of less than six years in most regions of China.
