Description

technical field [0001] The invention belongs to the field of cogeneration heat supply of coal-fired generating units, and in particular relates to a cogeneration unit coupling air energy storage compression heating system and an optimized operation method. Background technique [0002] Affected by factors such as the adjustment of fossil energy structure and environmental pollution control, the transformation and upgrading of my country's power structure has accelerated, and the development of new energy sources such as wind and light has developed rapidly and a high proportion of grid-connected power generation. Due to the intermittent, time-varying and fluctuating nature of renewable energy such as wind and light, the power system is required to improve its regulation capacity. However, at this stage, my country's power system does not have an excellent regulated power supply, and thermal power units that require installed capacity and power generation account for the majo...
