Abstract
The article analyzes the current issues of integration of renewable energy sources facilities into the Unified Energy System of Kazakhstan, problems and opportunities. Data on the installed capacity and power utilization coefficient of various types of renewable energy sources, such as wind power plants, solar power plants and small hydroelectric power plants, are presented. The problems of uneven generation of renewable energy, including significant seasonal fluctuations, are identified. The prospects for the development of renewable energy in Kazakhstan, including plans to increase capacity through auctions and the implementation of major projects, were considered. Special attention is paid to the tasks related to the balancing of electricity, the development of the national energy network and the introduction of energy storage systems. The importance of modern renewable energy forecasting and dispatching systems for improving the reliability of the country's energy system is also discussed. Based on the analysis, recommendations are proposed to improve the integration of renewable energy sources, which can contribute to the sustainable development of Kazakhstan's energy sector and ensure national energy security.
