This presentation will provide an overview of the study of a battery energy storage project intended to improve the reliability of the Eversource’s distribution system. The project includes installing a grid forming battery energy storage system. Grid forming inverters are one of the most promising technologies to overcome technical challenges of operating power systems with a large share of inverter-based renewable generation. These types of inverters have been deployed in small/islanded systems in the past few years, but the study looks at one of the largest/first deployments in a major interconnection. The study showcases the capability of grid forming inverters to operate reliably under ultra-weak grid conditions, improve the system reliability by seamless transition from the grid-connected to the islanded (microgrid) mode in case of a transmission or upstream distribution fault. The talk will discuss control stability and grounding challenges faced over the course of the study and mitigation measures to address those
