Implementation of SCA Optimized 2-DOF-PID Controller for Standalone PV System

Abstract

Maximum Power Point Tracking (MPPT) helps to reduce the oscillation around maximum power point
(MPP) and enhances the efficiency of the Photovoltaic (PV) system. Two Degree of Freedom PID (2-DOFPID)
based MPPT controller is implemented to generate adequate gate pulse for DC-DC converter. Sine
Cosine Algorithm (SCA) is a new optimization technique, which is adopted to elect the relevant best values
of the gain parameters of both 2-DOF-PID and PID controllers for better the performance. The performance
of proposed controller is validated with the Fuzzy logic controller (FLC), Proportional Integral Derivative
controller (PID) and Perturb & Observation (P& O).
