Advanced distributed multi-generation compressed air energy storage system and application method

Abstract

The invention belongs to the technical field of energy storage systems, and particularly relates to an advanced distributed multi-generation compressed air energy storage system and an application method. The compressed air energy storage system is a distributed multi-generation system, and comprises a power supply module, a cool supply module and a heat supply module, the compressed air energy storage system is further provided with a turbine, wherein the turbine is adjusted to enable the power supply module, the cool supply module and the heat supply module to switch between working modes ofthe modules. According to different season load requirements of users, the temperature of a turbine inlet in the compressed air energy storage system is adjusted, the system can provide cool, heat and electric loads at different seasons for the users, so that the load requirements of the users at of different seasons are met, various grade energy in the compressed air energy storage system is fully utilized, and the cost is reduced; and meanwhile, the energy utilization rate is increased.

Description

technical field [0001] The invention belongs to the technical field of energy-saving systems, and in particular relates to an advanced distributed multi-supply compressed air energy storage system and an application method. Background technique [0002] With the development of the national economy and the improvement of people's living standards, there is a serious shortage of power supply, and the peak-to-valley difference in power consumption continues to increase. During the peak period, the load increases, and more generator sets must be invested. If there are not enough spare sets, power cuts need to be cut; during the valley period, the load suddenly decreases, so some generator sets must be shut down. The frequent start and stop of peak-shaving units leads to a large waste of energy, which is very unfavorable to the economy and energy-saving work of power grid operation. Therefore, power demand side management has begun to attract people's attention. Through the mana...

Problems solved by technology

At present, the energy utilization of the compressed air energy storage system is mainly electricity and heat, but the type of load required by the user varies greatly with the seasons, such as electricity load and cooling load in summer, and electricity load and heat load in winter. The energy in the energy storage system is not fully utilized in different seasons, resulting in relatively low energy utilization throughout the year
