Methods of effective use of solar power system

Abstract

The paper presents the results of simulation and study of operating modes of a photovoltaic power plant with the maximum power point tracking controller. A number of search methods are considered: constant voltage method, open voltage method, short circuit method, method of observing perturbations and incremental conductance method. A complex model of the photovoltaic power plant with the controller has been developed. The simulation results are presented. The model validity was evaluated by the known technical characteristics of the Solarex MSX 60 module. The calculation results proved that the obtained volt-ampere and volt-watt characteristics of the model are compatible with those of the manufacturer. The review of various methods of searching the maximum power point for the solar battery and analysis of their performance under different climatic conditions can be of interest for a broad range of experts in the field of photovoltaics.
