Abstract

See full text

Systems and methods for voltage control in an energy distribution system (EDS), including measuring voltage and current at a node in the EDS where a Grid Energy Storage (GES) device is located. A simplified equivalent of the EDS is generated by identifying parameters for the equivalent and calculating phasors corresponding to the measured voltage and current. At least one of a voltage stability index or a voltage sensitivity factor of the EDS is calculated using the equivalent, and at least one of charging or discharging of the EDS is adjusted based on at least one of the voltage stability index or the voltage sensitivity factor to regulate and stabilize voltage of the EDS.
