The 10MW energy storage setup (comprising four 2.5MVA inverters) interconnected with the CenterPoint Energy system underwent modeling and examination. The configuration was replicated in PSCAD, PSSE, and ASPEN, meeting ERCOT standards. INS conducted assessments of model quality, including low voltage ride-through (LVRT), high voltage ride-through (HVRT), and evaluations of grid robustness to confirm alignment with ERCOT requirements. Additional analyses encompassed an investigation into reactive power and an assessment of harmonics.
