Evaluation of Voltage Control Effect for Data Acquisition Period Length from SCADA with IT Switches

Abstract

Measured data from IT switches are utilized in order to control voltage in Japanese distribution systems with photovoltaic generation systems. However, length of period from the data measurement to the data acquisition from IT switches by SCADA affects voltage control ability in a distribution automation system. In this paper, the effect of the length of the data acquisition period for voltage control by LRT and SVR is evaluated through numerical simulations in a distribution system model. Furthermore, the optimal length of the data acquisition period is determined according to PV penetration rate.
