Simulation Model of Solar Power Installation in Matlab Simulink Program

Abstract

The aim of this work is to develop a simulation model of a wind-solar power station with the display of elements and modes of its operation in the MATLAB software environment. Wind-solar power stations (VSES) are one of the most promising solutions for autonomous power supply of isolated consumers. Such systems can improve the environmental situation, as well as reduce the cost of delivering diesel fuel to remote regions. The structure of the VSES includes wind power and solar power plants, an accumulation, conversion and intelligent control system. As part of the model development work, software was analyzed that allows simulating such power complexes and, due to the high flexibility in the interaction of power supply system components, the MATLAB Simulink software environment was chosen. The article presents models of a wind power plant, a solar power plant, a battery system and a number of control systems. Based on the results of the work, the results of modeling and experiment were obtained and showed high efficiency of the system and sufficient accuracy of the models. The models are scalable and allow simulation of the modes of operation of the AECS.
