Investigation of Power Flow Analysis in Networked Microgrids

Abstract

In this paper, the power flow analysis of the Networked Microgrids (NMGs) is analyzed for different case studies of benchmark test systems. Multiple Microgrids (MGs) operating in combination enable high penetration of Distributed Energy Resources (DERs), which lowers electricity costs and improves the resilience and stability of the power network. This article’s benchmark test system for networked MGs connects and manages four separate MGs. An important technique for operational and planning studies of NMGs is power flow analysis (PFA). Each MG uses tie lines to work alone after initially operating as a group employing all of the MGs. The bus voltages, phase angles, active power loss, reactive power loss, iterations and computational time for NMGs were analyzed.
