Abstract

Anetworked microgrid with an energy management system connects several microgrids to exchange powerfor cost-effective and reliable operation. The feasibility study is required as a basis for developingan efficient networked microgrid energy management plan. This paper presented a detailed power flow analysis of a networked microgrid. Multiple IEEE microgrids are interconnected in the networked microgrid system, and various types of distributed generators are modeled based on PQ and PV control schemes. Different power flow algorithms based on the bus admittance matrix are used in the MATLAB simulation. Several case studies demonstrated the feasibility of the networked microgrid in grid connected and islanded modes as well as the effectiveness of the Fast-Decoupled (BX version) method in facilitating power exchange between microgridsto maintain supply-demand balance under normal and abnormal conditions.The results provedthat the Fast-Decoupled (BX version) method is significantlyfaster than the Fast-Decoupled (XB version) and Newton-Raphson methods andhas better convergence than the Gauss-Seidel method.
