Abstract: In this paper, a plug and play type autonomous-micro-grid system is considered. Multiple distributed generating sources (DGs) and loads interactions are considered pertaining to the stability of the micro-grid. The proposed method enables communication-less operation of each of the elements of the micro-grid system. Master-slave control of the distributed generating sources is considered in a decentralized manner to stabilize the overall micro-grid system. A novel signature frequency voltage injection method is proposed to identify the presence of master distributed generator and operation of backup distributed generator. The proposed method enables the changeover of a slave DG to a master DG in the case of failure of the primary master DG without any additional communication system, increasing the reliability of the whole micro-grid system. A detailed experimental study is carried out and the experimental results presented show the efficacy of the proposed system. © 2012 IEEE.
