Selection of Power Flow Algorithm for Closed Loop Volt-Var Control

This paper focuses on closed loop operational mode of Volt-VAr control (VVC) algorithm, as well as the power flow (PF) methods that can successfully be used to implement VVC. Two methods to implement efficient PF are Newton-Raphson approach and current iteration approach. The paper compares both approaches to find the one most suitable for the implementation of closed loop VVC algorithm.
