摘要
诸多电力基础设施建设援助项目表明,偏远社区的经济增长与电力消费存在着一定程度的互相促进关系,这意味着随着微网建设所促进经济增长的发生,初始阶段所建设的微网将很快难以满足不断增长的电力消费需求。因此,在依靠外界援助进行微网建设时,以多阶段规划的方式进行合理的资金配置,并考虑经济增长与电力供应的协同发展关系,将是一个很好的选择。该文在偏远社区的独立微网多阶段电源规划中,在各个发展阶段,考虑电力供应与经济发展之间的交互关系,以量化的方式表征偏远社区电力供应与经济发展的交互影响因素,并采用下行风险指标,分析模型中不确定性因素对于偏远社区经济发展影响中的不利方面,从而建立包含偏远社区经济增长最大、微网运行维护（O＆M）费用最小和经济增长下行风险最小3个目标的偏远社区微网多阶段多目标电源规划模型,并采用快速群搜索算法进行求解。理论和仿真结果验证了该电源规划方法的合理性和有效性。
Power infrastructure construction assistance projects show that the economic growth and power consumption of remote communities are mutually promoted by each other in a certain degree. This means that micro-grid construction can cause power consumption and economic growth, which in rum require enhanced micro-grid construction as the initial ones will soon be difficult to meet the growing power demand. Therefore, if micro-grid construction relies on outside help, allocating fund in the form of multi-stage planning and considering the coordinated development of economic growth and electricity supply will be a good choice. The multi-stage coordinated source planning of rural isolated microgrid in this paper took the lead in considering interaction relationship between power supply and economic development and quantitatively characterize it. Then, the downside risk index is used to analyze the disadvantage aspect caused by uncertainty factors in the economic development of rural isolated microgrid, and thus proposing objects including maximizing economic growth in remote communities and minimizing the micro network operation and maintenance （O＆M） costs as well as downside risks in economic growth. The model was solved by fast group search optimizer. The theory and simulation results verify the rationality and validity of the multi-stage coordinated source planning method.
