Popose a method to find the maximum power generator of PV system on Isc and Voc value Forecast Abstract: The maximum power point (MPP) of the photovoltaic cell system is related to the value of the open-circuit voltage (Voc) and the short-circuit current (Isc) according to the fill factor. Consequently, knowing these two parameters will be able to approximate the optimal working position of the system. This can significantly reduce the search area for Maximum Power Point Tracking (MPPT) solutions to increase convergence speed and performance. The content of this paper introduces a solution that applies two parameters Voc and Isc combined with the traditional perturbation and observation (P&O) algorithm to solve the above problem. The proposed solution is simulated in a PSIM environment to compare the performance and speed of MPPT with the traditional P&O algorithm under the same experimental operating conditions. The obtained results show that it has faster convergence speed, higher efficiency, and stable output waveform compared to the unimproved solution.
