Description
Technical Field
The utility model relates to an energy conversion and storage field, in particular to cold electricity federation of closed supplies energy storage system.
Background
Among all renewable energy sources around the world, wind energy accounts for 42% of them. Meanwhile, the wind power generation technology has great advantages in the aspects of technical maturity and economic benefit and various renewable energy distributed generation technologies, so that the wind power generation technology is a new energy distributed generation technology with the fastest development speed in the world. According to the forecast of the China renewable energy industry Association, the China wind power general installation will exceed 300GW by the end of 2020.
However, wind energy is affected by natural conditions such as weather, geographical position, airflow variation and other factors, and has the characteristics of great uncertainty, randomness, intermittency and the like, and great impact is brought to the dispatching, operation mode, reliability, electric energy quality and operation cost of a power grid. With the increasing wind power scale, the compatibility problem of the wind power and the power grid becomes more prominent, and a feasible solution is urgently needed to promote the large-scale utilization of the wind power. Among various methods for solving the wind power grid connection, the energy storage technology is known as a main approach for fundamentally solving the large-scale wind power grid connection problem. At present, the energy storage technology in domestic industrial technology mainly comprises pumped storage, Compressed Air Energy Storage (CAES), flywheel energy storage, electromagnetic energy storage, electrochemical energy storage and the like. The compressed air energy storage is a novel energy storage technology and gets more and more extensive attention of scholars at home and abroad.
The compressed air energy storage technology utilizes electric energy generated by intermittent renewable energy sources to drive a compressor unit to compress air, stores the electric energy in a high-pressure air mode, and releases the high-pressure air to drive an expander to do work and generate power when the electric energy is needed. Since Stal Laval proposed the use of underground caverns for compressed air energy storage in 1949, both domestic and foreign scholars have conducted a great deal of research and practice work on this, and two large power plants have been put into commercial operation in germany (Huntorf) and the united states (McIntosh), respectively. In addition, compressed air energy storage power station projects are in the process of construction in Japan, Italy, Israel and other countries respectively. However, most of the existing compressed air energy storage technologies are open-cycle technologies, and cannot provide cooling capacity, so that the system circulation efficiency is not high.
