6 FAQs about [Feeder power supply energy storage power supply]

What is a flexible energy storage power station (fesps)?

What is feeder RMS voltage?

Feeder RMS voltage (Phase A) for simultaneous operation of voltage regulation mode and real power limiting mode. The BESS recovers the feeder voltage linearly from t = 1 s to t = 3.5 s. The loads are modeled using the circuit load profile and typical distribution power factor values but were varied for different study cases.
