Simulation modeling of a power supply system taking into account the stochastic nature of energy generation and consumption processes

This paper presents the calculation of parameters and simulation modeling of the power supply system based on solar panels, taking into account the stochastic nature of the processes of energy generation and consumption. Through simulation in MATLAB® Simulink, the performance of the power supply system under the change of solar insolation and load power was evaluated. The method of controlling a bidirectional converter based on the calculation of the difference in Shannon entropy of energy generation and consumption flows is described.

THERMAL MODERNIZATION OF HEATING SYSTEM BY USING THE SOLAR ROOF

An important priority of Ukraine's economic policy is the careful use of energy. The country has a broad-based energy efficiency policy, and energy efficiency is complex, covering both the legislative framework and technical innovations. One of the effective ways to reduce energy costs for the needs of the national economy is to carry out thermal modernization of the heating system. In this article economic indicators of thermal sanitary measures during reconstruction of the heating system of the object are given.

Control system for positioning of solar panel

The problem of tracking the direction of the sun for the photovoltaic panel is considered. The types of solar power plants are analyzed and requirements for their control systems are formulated. The method and technical solution for managing the positioning of the solar panel are proposed. The accuracy of the photovoltaic panel guidance to the sun, as well as its protection against the destructive wind load, is provided by an efficient operational algorithm and using of step electric motors for building executive nodes.

Operation features of the converters of an autonomous power supply system

The article consideres the problem of extraction of maximum energy from a solar panel in an autonomous power supply system working with renewable sources under the condition of constant joint operation of a solar panel and a diesel generator. It is proposed to solve the problem taking into account the nonlinearity of the external characteristics of energy sources.
