Performed advanced inverter test cases demonstrating the grid-compatibility and support capabilities of residential-scale PV inverters. Designed and built a residential-scale PV system testing platform, executed voltage trip limit, frequency and voltage ride through, power factor, volt-var, volt-Watt test cases, extracted operational data and sub-cycle time coordinated performance data at in front and behind meter locations, and compiled an engineering report demonstrating results and findings that was shared with PJM membership.
