Abstract

There are many power point tracking (MPPT) algorithms that can be used to optimize the power of solar photovoltaic (PV) systems. The main differences between these algorithms are the use of digital or analog, ease of design, sensor requirements, convergence speed, validity interval, and hardware cost. Therefore, choosing the right algorithm is very important for users because it affects the electrical efficiency of the photovoltaic system and reduces costs by reducing the number of solar panels to generate energy. Model parameters are shown light-generated current IL 6.0092 A, Diode saturation current I0 6.3014e-12 A, Diode ideality factor 0.94504, Shunt registration Rsh 269.5934 ohms, Series Resistance Rs0.37152 ohms. In fact, using electricity at the module level can return 10.0% to 30.0% or more of annual operating costs, depending on the configuration and type of equipment. Of the three converter topologies listed in this article, the synchronous boost-buck converter makes the most sense because it can be used with a variety of PV modules and configurations. In addition, it can be seen from calculations, simulations and experiments that the performance of this topology is higher than other topologies.
