ABSTRACT:
This paper describes the characteristics and optimal
methods for the planning of stand-alone microgrid system, in order to improve the
power supply reliability, increase the coefficient of utilization of renewable
energy and reduce the cost of investment and operation. Next, the problems in the
optimal planning for a stand-alone microgrid system are summarized, including
the unique operational control targets, the flexible combination approaches and
the operation strategies of distributed generation energy supply system, and the
special requirements of the reliability of power supply quality factor from the
different users. And then, centering on the operational control and the
advanced energy management strategy, the optimal mathematical models and the
solving methods, the reliability assessment approaches and the improvement
measures of a stand-alone microgrid system, an overview of the general
situation of the recent research at home and abroad and the limitations of the
study are summarized. Finally, several problems, existing in the optimal
planning of stand-alone microgrid system, to be urgently solved, are put
forward.
