The electricity sector is undergoing a transformation as it moves towards a more digital and intelligent system. This transformation is driven by advances in technology, growing demand for clean energy, and a desire to improve efficiency and reliability in the electricity grid.
One of the key technologies enabling this transformation is the integration of digitization and intelligence into the electricity sector. By digitizing and automating various processes, the electricity sector is able to operate more efficiently and with greater reliability. For example, smart grid technology allows utilities to monitor and control the flow of electricity in real-time, enabling them to respond quickly to changes in demand and generation.
Battery energy storage systems (BESS) are a key technology in the transition towards a more sustainable and efficient energy system. These systems allow excess energy generated from renewable sources to be stored and used when needed, rather than being lost as waste. This not only helps to reduce greenhouse gas emissions and promote the use of clean energy, but also helps to stabilize the grid by balancing supply and demand.
Battery energy storage systems are becoming increasingly popular due to declining costs and advancements in technology. As battery prices continue to fall, more and more businesses and households are installing these systems to store excess energy generated from rooftop solar panels, for example. In addition, battery energy storage systems are becoming more flexible and efficient, making them a more viable solution for a wider range of applications.
In the electricity sector, battery energy storage systems play a crucial role in the trend towards digitization and intelligence. By storing energy and releasing it when needed, these systems help to ensure that there is always a reliable and consistent supply of power. This is especially important in areas with high levels of renewable energy generation, as fluctuations in wind and solar generation can cause instability in the grid.
Battery energy storage systems can also help to integrate renewable energy into the grid by smoothing out fluctuations in generation. This makes it easier for utilities to incorporate renewable energy into their energy mix, as the grid can more easily handle fluctuations in generation. In addition, battery energy storage systems can help to defer or avoid the need for expensive grid upgrades, as they can be used to store excess energy during periods of high generation and release it when needed.
In addition to their role in balancing supply and demand, battery energy storage systems are also becoming increasingly intelligent. Many systems are now equipped with sophisticated monitoring and control systems that can optimize performance and ensure efficient operation. For example, some systems can be programmed to release energy when demand is high and prices are high, or to store energy when demand is low and prices are low.
The trend towards digitization and intelligence in the electricity sector is expected to continue in the coming years, and battery energy storage systems will play a key role in this trend. As renewable energy continues to become more widespread and battery technology continues to improve, it is likely that these systems will become even more widespread and play an even more important role in the transition towards a more sustainable energy future.
In conclusion, battery energy storage systems are a critical technology in the trend towards digitization and intelligence in the electricity sector.

The energy storage system plays an increasingly important role in solving new energy consumption, enhancing the stability of the power grid, and improving the utilization efficiency of the power distribution system. arouse people's general attention.Its application scale is growing rapidly, and the safety of energy storage power stations has also attracted widespread attention.

There are three lines of defense for energy storage safety. The first is the material safety of the energy storage battery itself. The second is the fire protection design of the system, efficient thermal management, temperature control, early warning and intervention of thermal runaway, through BMS system linkage to cut off the power when thermal runaway occurs. The third is fire safety, effectively blocking the spread of energy storage battery fires, quickly cooling down and efficiently extinguishing fires, and preventing re-ignition.

The energy storage fire protection system is mainly composed of a detection part and a fire extinguishing part, which can realize the automatic detection, alarm and fire extinguishing protection functions of the protection zone or battery storage container. There are three common energy storage container fire protection systems on the market. One is the design idea of total submersion, which uses a gas fire extinguishing system to extinguish the fire; the second uses a gas fire extinguishing system + sprinkler; the third uses a Pack level fire extinguishing solution, and the solution is a fire extinguishing solution designed for each battery pack.

​Total submersion
System composition: fire extinguishing device, detection system, fire extinguishing agent delivery pipeline
1.Fire extinguishing device: Usually, the energy storage container fire fighting system will choose the heptafluoropropane fire extinguishing system. Experiments have shown that if the lithium battery catches fire in a closed environment, heptafluoropropane can quickly extinguish the fire and will not re-ignite in a closed environment; ultra-fine dry powder can also quickly extinguish the fire and will not resume Combustion; carbon dioxide can quickly extinguish the fire, but it will re-ignition;
2.Detection system:For lithium battery energy storage containers, we usually design a variety of detectors, such as temperature, smoke, combustible gas, carbon monoxide, hydrogen and other detectors, to sense the fire, and activate the fire extinguishing device through a prefabricated algorithm.
3.Fire extinguishing agent delivery pipeline: When the energy storage container fire protection system uses pipe network type heptafluoropropane, special gas pipelines will be used. Usually, the electrical area and the energy storage area will be separated. The electrical area adopts a suspended fire extinguishing device, and the energy storage area adopts a pipe network for formula heptafluoropropane. Arranging multiple nozzles through the pipe network to the protected area can ensure the uniform spraying of the fire extinguishing agent.

Gas fire extinguishing system + sprinkler
Energy storage container fire system design gas fire extinguishing system, while installing sprinkler system, is considered to be the most comprehensive and economical solution in the case of scientific design.The initial fire can be suppressed in time, buying valuable time for the next personnel to deal with it. If the fire is very large, the sprinkler will also be triggered. If the water resources are relatively sufficient, the fire can be completely suppressed normally.If the water resources are insufficient, it can also buy more valuable time for personnel to deal with.When the energy storage container is installed in a remote outdoor area and there is no water resource, there should be an emergency plan on site, such as how to quickly remove the battery on fire, and how to quickly remove the battery on fire. These basic plans and corresponding equipment such as a forklift is a must.

Pack level fire extinguishing solution
It detects and protects each battery pack through composite detectors, pipeline solenoid valves, fire extinguishing device spot spraying and other technologies.The core value point is that electrical fires can be effectively monitored and suppressed at the initial stage.The cost of Pack-level fire extinguishing is relatively high. In energy storage scenarios with a relatively high risk factor, a targeted fire extinguishing scheme is designed.

​The construction of the energy storage container fire protection system pays more attention to details. For example, the pressure relief port and emergency start and stop must have sealing measures. If the sealing is not good, there is a risk of short circuit;For example, sound and light and deflated lights must be protected against rain to reduce the risk of electrical short circuits.

       The temperature control system is an important link to ensure the normal operation of lithium battery energy storage. At present, air cooling and liquid cooling technologies are the mainstream temperature control solutions in the energy storage industry. The selection of energy storage temperature control technology should comprehensively consider safety, economy, and battery pack design, the environment, and other factors, not simply considering the cooling performance.
Refrigeration power requirements:

1. If the heat generation power of the energy storage project is low, the cooling demand is small, the air-cooling effect can be satisfied, and the adaptability is higher.
2. If the heat generation power of the energy storage project is high, the cooling requirements are large, and some scenarios require liquid cooling technology to meet.

Energy storage project cost:

1. At the initial stage of commercial development of energy storage, the cost sensitivity is high, which is conducive to higher air-cooled penetration rate, and the order of cost sensitivity is: large-scale energy storage > industrial and commercial energy storage > home storage
2. As the profit model of energy storage improves and the cost sensitivity decreases, the penetration rate of liquid cooling is expected to increase. To meet the safety requirements, large-scale energy storage projects are expected to introduce liquid cooling on a large scale.

Energy storage battery pack design: air cooling and liquid cooling are passively selected by the battery pack

1. The air-cooled energy storage system has simple structure, high reliability, and easy maintenance, but the system volume density is low.
2. The liquid-cooled energy storage system has a high-volume density and a compact system, which is difficult to install and maintain and has low reliability.

The environment of the energy storage project: the outdoor temperature will affect the cooling efficiency

1. Air-cooling is not suitable for places with extreme high temperature and heavy sandstorms: the cooling system relies on convective heat exchange with the outside air. The heat transfer efficiency is low when the outside temperature is high, and places with heavy winds and sandstorms are easy to invade and corrode the battery system.
2. Liquid cooling is not suitable for extremely low temperature and places far away from water sources: at low temperatures, the coolant is easy to freeze and cannot be used for thermal management. Liquid cooling relies on liquid convection to dissipate heat, so it consumes a lot of water.

Thermal management is a crucial aspect of ensuring the safe operation of energy storage systems, specifically in terms of improving the safety performance of batteries and maintaining stability during operation. There are two main angles to consider when improving the safe operation of energy storage systems:

1. Improving the safety performance of the battery itself through reducing the probability of punctures, short circuits, and other issues. This mainly depends on the technical improvement and innovations of battery manufacturers.
   
2. Maintaining the stability of the battery during operation through thermal management, keeping the battery within a safe operating range during charging and discharging, static, and other states, thus avoiding thermal runaway. This is primarily achieved through the use of a BMS (Battery Management System) to monitor the state of lithium batteries and temperature control equipment to regulate the constant temperature of lithium batteries.
   

BMS is the backbone of thermal management in energy storage systems. It is responsible for monitoring battery voltage, current, temperature, and other operating parameters, and adapting thermal management strategies accordingly. Temperature control, on the other hand, is the executor of thermal management in energy storage systems, keeping the energy storage battery in a suitable temperature and humidity state. By collecting temperature data and controlling heating, cooling, and other equipment according to a certain logic, the temperature control system is able to adjust the internal temperature and humidity of the energy storage system, ensuring that the battery is in a safe and efficient state.
In summary, thermal management is essential for the safe operation of energy storage systems and can be achieved by improving the safety performance of batteries, and maintaining stability during operation by implementing BMS and temperature control equipment. This ensures that energy storage systems are operating within a safe range, avoiding thermal runaway and providing efficient performance.

The BMS (Battery Management System) is an essential component of an ESS (Energy Storage System). It is responsible for monitoring and controlling the state of the battery pack, ensuring that the batteries are operating within safe parameters and maintaining their performance over time.
The BMS monitors key parameters such as battery voltage, current, temperature, and state of charge (SOC). It also has safety features such as over-voltage, over-current, and over-temperature protection to prevent damage to the battery pack.
The BMS also controls the charging and discharging of the battery pack. This includes managing the charging rate to optimize battery life and performance, and balancing the cells within the battery pack to ensure that they are all operating at the same voltage level.
Overall, the BMS plays a critical role in the overall performance and safety of an ESS. It allows the ESS to operate at peak efficiency, prolonging the life of the battery pack and ensuring that the system is always safe to operate.

PCS (Power Conversion System) is the core part of an energy storage system, which is responsible for converting currents. It is a bidirectional reversible AC/DC converter that can convert the electric energy output from the grid or new energy generation through the energy storage inverter into DC power, which charges the battery. The energy released by the battery can then be converted back into AC power through the energy storage inverter and fed back to the grid or used to supply power to the load.

Energy storage converters have two working modes: grid-connected and off-grid. In grid-connected mode, the PCS bidirectionally converts the energy between the battery pack and the grid. It has features such as anti-islanding, automatic tracking of grid voltage phase and frequency, and low voltage ride-through. According to the requirements of grid dispatching or local control, the PCS charges the battery pack with AC power from the grid and can also discharge the energy storage battery. During peak grid load periods, the PCS inverts the DC power of the energy storage battery into AC power and feeds it back to the public grid; it also feeds or absorbs active power to the grid, providing reactive power compensation when necessary.

In off-grid mode, PCS is able to disconnect from the main grid and meet the set requirements, providing local partial loads with AC that meets the power quality requirements of the grid electrical energy. It can also smoothly switch between grid-connected and off-grid modes.
