Impact of distributed generation and battery energy storage systems on an interconnected power system

This research describes the integration of Distributed Generation and Battery Energy Storage Systems into an IEEE 14-bus power system network, as well as the simulation of the effects of symmetrical and unsymmetrical faults and harmonics on the network during balanced, unbalanced, and no-load conditions. The paper will provide an elementary and detailed description of the network system used, power generation sources and the likely issues encountered, power stability concerns as they relate to power transmission and distribution to consumers, as well as consumer on-peak and off-peak usage situations on the network. It will also detail methods of improving the power quality and sustainability of our network system to withstand load demands, issues surrounding power transmission, and methods to integrate renewable energy. The Distributed Generation, which used only renewable energy, the Battery Energy Storage System, and the fault conditions were all simulated using the most efficient electrical engineering software, DIgSILENT Power Factory, and the results were used for the Load Flow (balanced and unbalanced) and harmonics analysis.
