How Can Energy Storage Power Stations Control Risks And Ensure Safe Operation?

What is battery storage power station?

A battery storage power station is a type of energy storage power station that uses a group of batteries to store electrical energy. Battery storage is the fastest responding source of power on grids, and is used to stabilise grids. At full rated power, battery storage power stations are generally designed to output for between one and several hours.

The energy storage power station is actually a power station set up to adjust the peak and valley power consumption problems.

As we all know, residents' electricity consumption for production and life will fluctuate greatly within 24 hours due to people's living habits. During the day and before 12 o'clock in the evening, electricity consumption is much more than after 12 o'clock in the evening. Although the power consumption can be adjusted by controlling the power of the power plant, it is still unable to adapt to such a large change, and a lot of electricity is wasted.

Therefore, the establishment of the energy storage power station, in simple terms, is to store the electricity we waste during the low peak period of electricity consumption and release it to the grid at the peak of electricity consumption to achieve peak reduction and valley filling. purpose.

How to prevent the risk of energy storage power station?

Nowadays, energy storage safety has become one of the focuses of people's attention all over the world. Because once a fire occurs, it will not only cause damage to the company's property, but also threaten the lives of staff and firefighters.

In 2019, the explosion of a battery energy storage project in Arizona in the United States directly caused 4 firefighters to be injured, two of which were seriously injured.

On April 6, 2021, the energy storage system (ESS) of a photovoltaic power plant in South Korea caught fire, and the area burned to 22 square meters, causing a total loss of approximately 440 million won (approximately RMB 2.58 million). After preliminary investigation, the relevant departments pointed out that the ignition point occurred inside the energy storage unit and involved a certain battery supplier.

How can energy storage power stations control risks and ensure safe operation?

The primary measure is to strengthen the safety protection of the energy storage system, prevent or reduce the impact of external stimuli on the battery body, actively suppress the amplification of hidden dangers, prevent the spread of local accidents, and prevent the local failure of the energy storage system from evolving into a global fire. The second is to strengthen the detection and early warning capabilities of energy storage power stations. The combustion and explosion reaction of the energy storage battery is sudden, but the external stimulus that triggers the combustion and explosion of the energy storage battery is traceable; the third is for the hidden dangers of different types of energy storage accidents. , Formulate emergency plans for failures and fire-fighting measures, and strictly abide by them, first of all to ensure the safety of personnel.
