Study of Maximum Power Point Tracking (MPPT) Techniques in a Solar Photovoltaic Array
Journal Title: GRD Journal for Engineering - Year 2017, Vol 2, Issue 5
Abstract
Maximum power point tracking (MPPT) is used in photovoltaic (PV) systems to maximize the PV array output power, irrespective of the temperature and irradiation conditions and the load electrical characteristics. This paper presents a practical implementation of perturbation and observation (P&O) and incremental conductance (IncCon) algorithms based on PIC18F452 microcontroller for tracking of the maximum power generation from PV system. These algorithms are widely used because of its low-cost and ease of realization. Proposed P&O and IncCon algorithms are implemented and tested under different loads, and the test results are analyzed and compared. The results show the performance of the IncCon algorithm in tracking MPP is better than the P&O algorithm and the experimental results of IncCon algorithm indicate that the feasibility and improved functionality of the system with have high-efficiency.
