In the last decade, there has been a substantial surge in the advancement of research into the maximum power point tracking (MPPT) controller. The MPPT approaches, on the other hand, continue to be in high demand due to the ease and simplicity with which tracking techniques can be implemented on the maximum power point (MPP). Diverse MPPT approaches and their modifications from various literature are categorized and thoroughly explored in this work, which is divided into two sections. The discussions are centered on the primary goal of attaining the most extraordinary feasible MPPT technique that produces the best results at the lowest possible expense. In order to determine which MPPT approaches to use, evaluations from earlier literature are used to guide the decision. In this section, we will examine the evaluation of the MPPT technique in two sections. Previously, in Part I, we explored the MPPT techniques based on constant parameters and trial-and- error. Part II of this article will examine the MPPT technique, which is based on mathematical computation, measurement, and comparison, and the algorithm development that has occurred in recent years. Furthermore, this section’s assessment for selecting MPPT approaches is based on previous literature reviews. To aid with this selection, the following criteria for the MPPT approach are proposed: sensors and analog/digital requirements, costeffectiveness, simplicity, stability, efficiency, and tracking speed. This enables the reader to select the MPPT technique that is most appropriate for their application.

W artykule przedstawiono aspekty praktycznej realizacji jednofazowego, izolowanego systemu fotowoltaicznego dołączonego do linii elektroenergetycznej. Układ ten bazuje na topologii przekształtnika DC-DC podnoszącego napięcie, współpracującego z falownikiem napięcia (mostek typu H). Publikacja koncentruje się głównie na sposobie podłączania układu do sieci zasilającej kontrolowanym za pomocą zmiennej struktury sterowania. Porównaniu poddano również metody typu Perturb-and-Observe oraz Incremental Conductance poszukiwania punktu mocy maksymalnej, pozyskiwanej z modułów fotowoltaicznych.

The paper presents aspects of practical implementation of a single-phase, insulated, grid-connected photovoltaic system. Its topology is based on DC-DC boost converter cooperating with voltage source inverter (H-bridge type). In general, the article is focused on the proper connection of PV system to the mains with usage of variable control structure. Moreover, the comparison of Perturb-and-Observe and Incremental Conductance Maximum Power Point Tracking algorithms is also presented.
