Design and Tuning of Genetic algorithm based Robust Fractional Order Controller for Autonomous Micro-grid VSC System

Abstract

A robust controller design for the voltage control of an autonomous three-phase voltage source converter
(VSC) is pro-posed. As compared with the conventional proportional plus integral (PI) controllers and fractional order
controllers, Genetic Algorithm based FOPI (GAFOPI) controller make the VSC system robust due to their fractional
characteristics. This work proposes GAFOPI controller for VSC, the parameters of voltage controller of VSC are tuned
with the proposed method. The effectiveness of the proposed method is compared with conventional PI and FOPI
controllers on standard test system. Results demonstrated that the proposed method is better in performance compared
with conventional and FOPI controllers.
