In order to maintain customer voltages within allowable limit (220±13V) as much as possible, tap operation strategy of SVR(Step Voltage Regulator) installed in distribution system is very important, considering the scheduled delay time(30 sec) of SVR. However, the compensation of BESS (Battery Energy Storage System) during the delay time of SVR is being required because the customer voltages in distribution system interconnected with PV (Photovoltaic) system have a difficultly to be kept within allowable limit. Therefore, this paper presents the optimal voltage stabilization method in distribution system by using coordination operation algorithm between BESS and SVR. Based on the modeling and simulation of SVR and BESS using the PSCAD/EMTDC, it is confirmed that customer voltage in distribution system can be maintained within allowable limit. © Research India Publications.
