Hybrid Controller in Immune Feedback Control Algorithm for Distribution Static Compensator

Abstract

This paper bestows a biological immune feedback control for DSTATCOM hinge on fuzzy logic techniques. The proposed algorithm relies on adaptive and self-corrective. An immune feedback algorithm proposed for DSTATCOM can balance loads, estimate fundamental grid currents from nonlinear load currents, maintain unity power factor, reduce harmonics of the supply currents and can mitigate reactive power. DSTATCOM’S configuration chosen relies on 3-Φ VSC that is appropriately controlled as a shunt compensator to perform on power quality issues. Replacing of ANFIS-PID (hybrid) controller in immune feedback control where, ANFIS is collaboration of fuzzy logic and neural network system, hybrid controller for DSTATCOM can perform better over PI controller. Simulation is directed using MATLAB to prove performance of the system by replacing hybrid controller, enhancement in power quality (PQ) is achieved.
