This paper describes the characteristics and optimal methods for the planning of stand-alone microgrid sys- tem in order to improve power supply reliability, utilization of renewable energy and reduce cost of investment and op- eration. The problems of optimal planning for stand-alone microgrid system are summarized, which includes unique operational control targets, flexible combination approaches and operation strategies of distributed generation energy supply system and special requirements of the reliability of power supply quality factor regarding different users. Cen- tering on the operational control and the advanced energy management strategy, the optimal mathematical models and the solving methods, the reliability assessment approaches and improvement measures of the stand-alone microgrid system, an overview of the general situation of recent researches at home and abroad and the limitations of the study are summarized. Finally, several problems in optimal planning of stand-alone mierogrid system to be urgently solved are put forward.
