System Research in Energy| Резюме: | We consider the commitments of countries to reduce greenhouse gas emissions to the environment and described other causes of increase in the share of renewable energy sources in the global structure of electricity generation. We present the parameters of growth of the share of solar and wind power plants in power systems and further prospects for the development of this power industry in the world. We present the cost of introducing solar and wind power plants and give further forecasts for the cost reduction of these technologies. The problems that arise in the operation of power systems with significant volumes of unstable generation in their structure are analyzed. The specific character of generation, which is associated with weather conditions, is considered, and ways to solve problems, used in the world, are examined.The necessity of introducing systems of electric energy storage, intended to ensure and maintain the high quality of electric energy, frequency regulation, improving the reliability of power supply, smoothing and transfer of the peaks of daily power consumption schedules in a power system, and its balancing are described.We also analyzed present-day rates of the introduction of systems of electric energy storage in the world and prospects for the further development of this industry. The types of existing storage systems, their main characteristics, advantages and shortcomings are described. Attention is concentrated on electrochemical systems of electric energy storage, they are compared by the type of chemical reaction, the advantages, and shortcomings of electrochemical systems are described for using various materials.A description is given for the applications that electric storage systems must carry out in integrating renewable energy sources into a power system. We characterize the most efficient types of electric energy storage systems, which are necessary for various applications in integrating unstable generation into power systems. Implemented projects for the introduction of electrochemical systems of electric energy storage, which are used in the world for the integration of solar and wind power plants, are examined. We also give conclusions concerning the prospects for further development and feasibility of using energy storage systems. |
