The issue of the concept of creating a control system based on smart grids of renewable energy sources, namely a diesel-solar power plant, is being considered. The main attention is paid to the method of saving diesel fuel by switching on solar power plant modules using automatic input of backup power. The purpose of the article is to familiarize with the calculations of solar and diesel power plants in the conditions of Southern Kazakhstan, made on the System Advisor Model program. A characteristic is given about the «green» initiatives of the energy sector of the Republic of Kazakhstan, namely, saving energy resources by replacing coal burning with gas, saving diesel fuel burning at diesel power plants, covering the electric energy deficit with the introduction of renewable energy sources. The problem of the study is the use of the Smart Grid concept in the power supply and power consumption of electric energy consumers. The research is aimed at studying hybrid renewable energy sources, namely the joint operation of a diesel and solar power plant. The main goal was to create a unified intelligent control system for monitoring and forecasting the main technical parameters of the generated energy.
