Impact of the weightings of different criteria in selecting the suitable microgrids when forming a system of coupled microgrids

Abstract

© 2016 IEEE.A microgrid (MG) is expected to supply its demand independently; however the load and generation intermittency may result in the overloading of an MG. This problem can be addressed by coupling suitable neighboring MGs with the overloaded one(s). The selection of the suitable MGs can be based on different criteria such as the level of the available surplus power, reliability, dependency on renewable energies, power losses, electricity costs and CO2 emissions in the neighboring MGs. Each criterion may have a different weighting. This paper evaluates the impact of the weightings of each criterion on the outcome of the alternative selection strategy and presents the sensitivity of the selection procedure on the weightings of each criterion.
