Structural and computer optimization model of a solar-wind hybrid electrical system in the software environment Matlab Simulink

Abstract

The article describes the structural and computer optimization model of a photo-wind hybrid electrical system to determine the design parameters of the solar and wind equipment and optimization of their interconnected operation. The model is developed in the graphical software environment simulation MatLab Simulink and used for multidimensional data analysis. It lists only basic details on working in this software environment which are necessary for the realization of basic algorithms. The combination of a vertical wind turbine with photovoltaic cells on its blades, as well as a set of batteries, allows continuous power supply, even at total absence of wind and at night. A wind turbine and a solar surface with solar cells are generating electricity. Structural and computer model of a solar-wind hybrid electrical system contains a number of key subsystems that ensure their efficiency and subsystems that contribute to the work of the key subsystems (wind turbine, induction machine, a three-phase bridge rectifier, battery, etc.). The crucial element can be considered to be a subsystem of “wind turbine” and “solar battery”. A large number of subsystems promoting the operation of key subsystems comprise switches, rectifiers, controllers, the inverter, blocks and blocks for communication of the key subsystems' control parameters.
