The invention discloses a
planning method and
system for optimizing a micro-grid containing
distributed power sources and
stored energy, wherein the
planning method and
system are based on an intelligent optimization
algorithm. The
planning method is used for optimizing the micro-grid containing the
distributed power sources and the
stored energy, and comprises the steps that basic data are provided for a planning and design scheme, and modeling and load flow calculation are performed on an area to be planned; a micro-grid wiring mode suitable for the area to be planned is determined; site locations, to be chosen, of the multi-type
distributed power sources are determined;
a site distribution and capacity determining model is established, and a grid frame of the micro-grid containing the distributed power sources and the
stored energy is planned and designed; a joint planning scheme and a joint planning module under a decided investment subject are formed; the joint planning scheme is output and evaluated. According to the planning method and
system for optimizing the micro-grid containing the distributed power sources and the stored energy, on the basis of basic characteristic study of the distributed power sources and the micro-grid, planning for optimizing the micro-grid containing the photovoltaic power sources is systematically studied, the positions, capacities and the grid frame structures of all kinds of distributed power sources in the micro-grid in the specified planning area are reasonably allocated, and the micro-
grid optimization planning scheme which is complete, effective and high in integrity, and is closely integrated with
engineering practice is established.
