Description

technical field [0001] The invention relates to an energy storage power generation system, in particular to a rock energy storage power generation system. Background technique [0002] In the context of carbon peaking and carbon neutrality, electricity will become the main force in promoting energy transformation. Power generation, transmission and transformation, and electricity consumption are the three major elements of traditional electricity. There is CO in traditional thermal power generation 2 , SO 2 , NO x The discharge of dust and solid waste has brought serious environmental pollution problems. [0003] With the innovation and progress of technology, power generation, power transmission and transformation, power storage and power consumption will become the four elements of modern power. Energy storage will enter a period of rapid development. The existing energy storage methods mainly include: large-scale construction of pumped energy storage, electrochemical...

AI Technical Summary

Problems solved by technology

Energy storage will enter a period of rapid development. The existing energy storage methods mainly include: pumped energy storage that can be constructed on a large scale, electrochemical energy storage, compressed air energy storage, flywheel energy storage, heat storage, and cold storage. Affected by complex technical conditions, pumped hydro storage accounts for about 90% of power energy storage by virtue of its advantages, and other energy storage methods only account for about 10% of the total. However, pumped hydro storage has strong geographical requirements and is difficult to develop in a distributed manner. , the rest of the existing energy storage methods are also difficult to meet the requirements of large-scale distributed energy storage

[0004] After renewable energy has become the mainstream of the market, energy security has become a new challenge. Whether it is the safety and energy density of energy storage technology after large-scale, or the possibility of secondary disasters caused by energy storage configuration after disasters, there are currently Various energy storage technologies are still not up to the level of undertaking ultra-large-scale energy strategic reserves
