摘要：Integration of energy storage infrastructures into electrical grids represents a crucial milestone in the transition towards energy systems with high penetration of renewables. However, the high cost of the currently available technologies is a significant barrier for their implementation on the industrial scale. High temperature thermal energy storage systems, in combination with bottom steam cycles, are being investigated as potential cost effective alternatives to traditional large-scale energy storage technologies. In this study, by adding a high temperature heat storage device in the cold (hot) section of the reheating pipeline and taking the 300MW extraction steam turbine as the research object, it is concluded that the introduction of the high temperature heat storage device can improve the consumption of wind power and greatly reduce the power supply of the coal-fired unit. The coal consumption rate is analyzed. The ideas and methods for solving the energy consumption of the renewable energy and reducing the peak energy consumption are provided.
