Abstract

The invention provides a compressed air and liquid air combined energy storage power generation system. An outlet of a primary air compressor unit is connected with a compressed heat storage and utilization device. The compressed heat storage and utilization device is connected with a compressed air storage unit. The compressed heat storage and utilization device is connected with a liquid air storage unit. The compressed air storage unit and the liquid air storage unit are both connected with an expansion power generation unit. Through the structural arrangement, compressed air and liquid air combined power generation can be achieved. On one hand, the problem that the energy storage density of a compressed air energy storage power station is low can be solved; and on the other hand, the response rate of a liquid air energy storage power station can be increased. Thus, the flexibility and operation efficiency of an air energy storage system are effectively improved. Meanwhile, the compressed air energy storage power station and the liquid air energy storage power station share the primary air compressor unit, the compressed heat storage and utilization device and the expansion power generation unit, and the investment cost of facility equipment is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of liquid air energy storage, in particular to a combined energy storage and power generation system of compressed air and liquid air. Background technique [0002] Air energy storage is an emerging large-scale green energy storage technology. Air energy storage includes compressed air energy storage and liquid air energy storage. Among them, the conventional compressed air energy storage power station has low energy storage density and large area, but the system is simple and the response is fast. The liquid air energy storage power station has high energy storage density and small footprint, but the system is complex and the response is slow. At the same time, when the compressed air energy storage power station and the liquid air energy storage power station are independently established, the corresponding equipment and facilities need to be set up respectively, and the investment cost is relatively lar...
