Causes of attenuation of electrochemical energy storage power stations

What are some safety accidents of energy storage stations?

Some safety accidents of energy storage stations in recent years . A fire broke out during the construction and commissioning of the energy storage power station of Beijing Guoxuan FWT, resulting in the sacrifice of two firefighters, the injury of one firefighter (stable condition) and the loss of one employee in the power station.

What happened at Jinyu thermal power plant?

The fire occurred in the energy storage power plant of Jinyu Thermal Power Plant, destroying 416 energy storage lithium battery packs and 26 battery management system packs, and resulting in the energy storage power plant being out of service for more than 30 days.

Are electrochemical energy storage power stations safe?

Such as the thermal-electrical-chemical abuses led to safety accidents is increasing, which is a serious challenge for large-scale commercial application of electrochemical energy storage power stations (EESS).

What is energy storage technology?

Energy storage technology is an effective measure to consume and save new energy generation, and can solve the problem of energy mismatch and imbalance in time and space. It is well known that lithium-ion batteries (LIBs) are widely used in electrochemical energy storage technology due to their excellent electrochemical performance.

What is energy storage power station (EESS)?

The EESS is composed of battery, converter and control system. In order to meet the demand for large capacity, energy storage power stations use a large number of single batteries in series or in parallel, which makes it easy to cause thermal runaway of batteries, which poses a serious threat to the safety of energy storage power stations.

How to solve communication delay between inverted power station and EES?

For the problem of communication delay between inverted power station and EES, special optical channel is used for the communication between HVDC transmission system stations, while the upper limit of the propagation speed of optical communication is 300 km/ms.
