    Abstract

    This paper describes distribution voltage estimation and a control method using measured data from sectionalizing switches with sensors which are called IT switch. The voltage estimation is based on Particle Swarm Optimization (PSO) and all distribution line voltages are estimated by minimizing the weighted sum of voltage and current error at IT switch. The voltage control maintains all the estimated node voltages within the proper range by changing tap of a LRT in a distribution substation. In order to check the validity of the proposed method, numerical and experimental simulations are carried out on a distribution system model.
