Abstract

Solar photovoltaic technology is dealing with the challenge of optimal power production from PV cells under all circumstances. This is possible by forcing the PV system to operate at maximum power point (MPP). Therefore, an algorithm is designed to take the operating power point towards MPP using an electronic circuit. The most used algorithm in the market is P&O due to its simple structure, easy implementation, and cheap circuitry. Whereas the weaknesses associated with P&O are steady state oscillations, PV array dependency, and slow tracking speed. We have put efforts into reducing the tracking time and removing the steady-state oscillations. After the detailed analysis, we have made some structural changes to get the required results. The proposed technique is named the optimized P&O (OP&O) algorithm. Both algorithms have been applied to the 90-watt PV system specifically designed for this purpose. The PV system with both algorithms is simulated in MATLAB/Simulink at different loads. The results have shown remarkable achievement in tracking speed, steady state oscillations, and ease of implementation.
