Development in distributed energy resources (DER) technologies has opened new opportunities for on-site power generation by electricity users to cover the growing customer requirements for electric power. The Consortium for Electric Reliability Technology Solutions (CERTS) microgrid represents an entirely new approach to integrating DER. MG integration provides enhancement of reliability, power quality, and the lowering the operational costs. This paper introduces the modeling and analysis of multiple photovoltaic cells (PVs), battery storage, and controllable load within a CERTS microgrid. The operational characteristics of the simulated CERTS microgrid are investigated under different operating conditions, and a fault analysis study is carried out. The modeling stability under different operating conditions has been evaluated. The paper also offers a thorough analysis of the MG structure and the related protection and control issues The modeling and different case studies are carried out using the Matlab Simulink platform.
