AI Technical Summary
Traditional thermal power plants suffer from fragmented electrical and thermal systems, lack of global optimization, inability to effectively utilize cheap electricity for energy storage, insufficient regulation capabilities, and difficulty in coordinating with the power grid, resulting in unstable heating, high energy costs, and inability to participate in grid frequency regulation ancillary services.
The turbine exhaust heat and power co-operation system adopts integrated energy storage, including a steam source extraction unit, an electro-thermal coupled energy storage module, and an intelligent scheduling and control unit. The intelligent scheduling and control unit integrates multi-source information in real time, formulates multi-modal collaborative operation strategies, and utilizes the energy storage unit and steam storage unit to realize the spatiotemporal transfer of energy and rapid frequency regulation.
It enables efficient steam generation and energy storage during grid off-peak hours, prioritizes the use of stored energy during grid peak hours, reduces electricity purchase costs and absorbs renewable energy, provides second-level frequency regulation auxiliary services, ensures stable steam parameters, and improves the economic efficiency and flexibility of power plant operation.
