Hierarchical based coordination strategy to efficiently exchange the power among micro-grids

Abstract

Micro-grid (MG) is an emerging component of a smart grid and it is increasing the efficiency and reliability of the power system with the passage of time. MGs often need power in order to fulfill its load requirements, which is transmitted form macro station (MS). Transmission of power from MS cause power line losses. To decrease these power line losses, a hierarchical based coordination (HBC) strategy is proposed for efficiently exchanging the power among MGs. HBC aims to decrease power line losses by making hierarchical coalitions. Results are evaluated and compared with conventional non-coordination model (NCM). This comparison shows the effectiveness of proposed HBC strategy. Results indicate that HBC has decreased the power line losses by 40.1% as compared to conventional NCM.
