Design of coal mine energy storage emergency power supply system

Why do we use coal to develop underground space resources?

While making full use of coal to develop underground space resources, it realizes power conversion and storage, stabilizes the power system's cycle and voltage, promotes the circulation of mine water, and guarantees flood storage and water transfer.

Can a pumped storage power plant improve a coal mine's Peak regulation mode?

The construction of a pumped storage power plant within an underground coal mine has the potential to improve the power system's peak regulation mode as well, but also solve the contradiction between energy and load. Although it is a novel approach, there are still some dangerous obstacles to overcome before garbage can be used effectively.

What is coal underground space electrochemical energy storage?

CUEES concept and technical requirements Coal Underground space Electrochemical Energy Storage (CUEES) makes full use of the underground space of coal mining to store or release electrical energy (various types of batteries) through reversible chemical reactions, so as to achieve efficient use of electrical energy, as shown in Fig. 20 [ 94 ].

How safe is underground electrochemical energy storage in coal mines?

Because underground electrochemical energy storage in coal mines needs to be equipped with a large number of batteries, it requires laying a large number of wires, which may lead to fires, so CUEES needs to be equipped with a complete and effective safety monitoring and protection system during operation to ensure safe operation. 6.2.

How to ensure safe operation of coal mine energy storage facilities?

(1) Establish strict environmental protection standards and emission limits to ensure that coal mine energy storage facilities do not have a negative impact on the environment. (2) Establish a safety supervision mechanism to ensure the safe operation of coal mine energy storage facilities, and formulate necessary safety standards and norms.

Can underground space energy storage technology be used in abandoned coal mines?

The underground space resources of abandoned coal mines in China are quite abundant, and the research and development of underground space energy storage technology in coal mines have many benefits.
