Description

technical field [0001] The invention relates to the field of power grid peak regulation, in particular to the fields of distributed energy utilization, cross-seasonal energy storage and peak regulation in thermal power plants. Background technique [0002] Distributed energy is an energy supply method built on the user side, which can be operated independently or connected to the grid. It is a system that determines the mode and capacity of resources and environmental benefits by maximizing the user's various energy needs and resource allocation status. System integration and optimization, a new type of energy system that adopts demand-responsive design and modular configuration, is a decentralized energy supply method relative to centralized energy supply. [0003] During the power generation process of thermal power plants, a large amount of low-grade heat from steam turbine exhaust is discharged into the atmosphere through cooling towers or air-cooling islands, resulting ...
