Using ANN to Estimate the Voltage of Unobservable Buses When One PMU or its Communication Fails

Abstract

Abstract. In monitoring system, the PMUs send their data to a control center. If one PMU fails or its communication fail, the data of that PMU do not send to the control center. This lack of data leads to some unobservable buses. In this paper, Artificial Neural Network (ANN) has been used to estimate the voltage of unobservable buses. We implement this method in IEEE 14-Bus.
