Abstract
In recent years, solar energy has become increasingly popular and receiving a lot of attention from several research. The effectiveness of Photovoltaic (PV) arrays is affected by the output power of these systems, which is dependent on temperature and solar radiation. Though, in order to excerpt the greatest power feasible from a Photovoltaic arrays, Maximum Power Point Tracking (MPPT) control method is applied. The MPPT controller attempts to gather the most energy even in conditions of partial shading. MPPT algorithms are not effective on Partial Shading Conditions (PSC), where complex algorithms are effective but need high computational resources and practice. To enhance the efficacy and economy of Photovoltaic systems, perturb and observe (P&O) algorithm based MPPT approach is proposed in this paper, which tracks the MPP even in PSC. With the P&O MPPT approach, solar Photovoltaic is utilized properly in a variety of operating conditions and a constant power supply is provided to the consumer uninterruptedly. As a result, the control system structure of the suggested method is simpler and more constant, which is simulated by the MATLAB software.
