Abstract The optimization of energy in a photovoltaic conversion chain remains a topic of study. The maximum power point tracking MPPT is considered the most appropriate solution to ensure the extraction of the maximum power which a photovoltaic generator can provide. The results clearly show the efficiency of the improved algorithm which contributed to the increase of the tracking speed with negligible fluctuations when the MPP is reached, and especially in rapid variation of insolation.

One of the ways to increase their conversion efficiency is accurate method of extracting maximum power from PV panel by spotting the Maximum Power Point MPP. As the solar radiation is not constant always, the available maximum power also varies throughout the day and hence Maximum Power Point Tracking MPPT becomes continual and essential. Wrong tracking direction, less convergence speed and oscillations around MPP are the drawbacks of this algorithm which decelerate its usage to the maximum extent. Many researchers develop proven concepts in the literature to overcome these drawbacks. Without comparative assessment, using the developed concepts will not meet the expected outcome for PV panel designer. Without detailed review of recent developments, the researchers may not find scope for future developments towards excellence in this area. The students to become researchers require detail analysis of original concepts with present progresses.

Show all documents Maximum Power Point Tracking For Photovoltaic System Using Modified Perturb and Observe Method The comparison between the existing method perturb and observe and proposed method modified perturb and observe method has been done. Here,the results indicate that PV conversion system using modified perturb and observe method which has higher conversion efficiency and it tracks the exact maximum power point at less time with higher tracking speed than perturb and observe method. Therefore, the modified Perturb and Observe method was best preferred due to its higher tracking efficiency. When PV power increases and PV voltage decreases and vice versa, the perturb direction step size subtracted for next cycle of the perturbation. The system will oscillates the around MPP this will result in loss of energy.

Maximum power point tracking MPPT [1] [2] or sometimes just power point tracking PPT , [3] [4] is a technique used commonly with wind turbines and photovoltaic PV solar systems to maximize power extraction under all conditions. Although it primarily applies to solar power, the principle applies generally to sources with variable power: for example, optical power transmission and thermophotovoltaics. PV solar systems exist in many different configurations with regard to their relationship to inverter systems, external grids, battery banks, or other electrical loads. As these conditions vary, the load characteristic that gives the highest power transfer efficiency changes.
