Abstract

In this paper, a system identification based method is proposed to determine the transfer function of a cascade multilevel inverter STATCOM connected to a distribution system in order to design control system for mitigating voltage fluctuations. The identified model has been used for determining the voltage controller parameters using Ziegler-Nichols technique. The feasibility of the proposed methodology has been validated through digital simulation using MATLAB/SIMULINK on an 11-level cascade multilevel STATCOM under different operating conditions.
