A Maximum Power Point Tracking Technique Based on Ripple Correlation Control for Single Phase Photovoltaic System with Fuzzy Logic Controller

This paper proposes a novel maximum power point tracking (MPPT) technique by integrating ripple correlation control (RCC) with fuzzy logic controller (FLC) for single-phase, single-stage grid-connected photovoltaic (PV) systems. RCC is suitable for implementing MPPT in single-phase PV systems and it possess advantages of less complexity, low cost of implementation and high rate of convergence. The proposed MPPT technique based on RCC integrated with FLC is working satisfactorily under varying insolation conditions. The effectiveness of the proposed technique has been verified by performing numerical simulation studies.
