Abstract

The invention provides a compressed air energy storage system with a dynamic load response function and a control method. Automatic load adjustment in a compressed air energy storage stage and an energy release stage is realized through a load controller, and the load controller comprises a load demand control unit and a frequency difference load control unit, wherein the input end of the load demand control unit is connected with a first signal receiving module, the output end of the load demand control unit is connected with a first signal processor and a first signal output module, and the input end of the frequency difference load control unit is connected with a second signal receiving module; the output end of the frequency difference load control unit is connected with a second signal processor and a second signal output module; through module control, response and primary frequency modulation of dynamic load requirements of compressed air energy storage in the two stages of energy storage and energy release are effectively achieved, and the supporting capacity of the compressed air energy storage on a power grid under the safe boundary condition is effectively improved.

Description

technical field [0001] The invention relates to the technical field of electric energy storage, in particular to a compressed air energy storage system with a dynamic load response function and a control method. Background technique [0002] Compressed air energy storage is one of the key supporting technologies for building a new power system with new energy as the main body and realizing large-scale energy storage. Compressed air energy storage mainly drives the air compressor by using the remaining electricity when the load of the power system is low. Pressing into a large-capacity air storage chamber, that is, converting electrical energy into storable potential energy of compressed air, when the power generation capacity of the system is insufficient, the expander is then driven to generate power to meet the peak-shaving needs of the system. Compressed air energy storage has the advantages of large capacity, long service life, and good economy. However, limited by the ...
