doi:10.3969/j.issn.1000-7229.2015.08.018

Abstract

Abstract:

According to the existing problems in the capacity configuration of current micro-grid, a new multi-objective optimization method was proposed for the capacity configuration of micro-grid, by which the combined solution and configuration optimization of distributed generation capacity and energy storage capacity in micro-grid planning could be carried out at the same time. Taking a auxiliary power system in 1 000 kV substation as example, this paper applied micro-grid planning software DGPO to design three different supplementary power schemes for UHV auxiliary power system, including photovoltaic storage micro-grid system, wind storage micro-grid system and wind-photovoltaic storage micro-grid system. Finally, a grid-connected/off-grid photovoltaic storage micro-grid system was recommended as supplementary power for substation.

Key words: auxiliary power system, micro-grid system, multi-objective optimization, energy storage system
