Abstract

Load-shedding and curtailment of renewable sources are common mechanism to prevent temporary overloading and over-generation in autonomous microgrids (MGs). However, these problems can be addressed by interconnecting the neighbouring MGs to share power among them. In such a scheme, the interconnected MGs, termed as coupled microgrid (CMG), are controlled to supply their local loads, as well as the loads in the neighboring MGs through an interconnecting three-phase ac link with back-to-back power electronics-based converter. This paper has proposed a suitable control mechanism to realize power sharing amongst the MGs within a CMG, when operating in different conditions. The efficacy of the proposed power sharing and control mechanisms are validated through simulation studies using PSIM ® .
