In this paper, we present results from a power hardware-in-the-loop (PHIL) simulation that was performed to evaluate the impacts of battery energy storage system (BESS) functionalities on a distribution feeder. The PHIL platform includes a simulated distribution grid in a real-time digital
simulator (RTDS), AC and DC power amplifiers, and a battery inverter as the device under test. Guidelines for setting up a PHIL platform to evaluate the impact of battery energy storage system (BESS) functionalities are provided. Accelerated timeseries PHIL simulations of peak shaving and volt-watt
functionalities were performed using a 540 kVA BESS. These experimental results illustrate how PHIL simulations can be used to evaluate the impact of BESS functionalities on the distribution grid prior to installation in the field.
