What is the use of industrial energy storage system?
Today, carbon reduction has become a global consensus. Affected by factors such as economic recovery, the early arrival of high-temperature power consumption peaks, and "water shortages" in major hydropower provinces, many regions are facing severe challenges in electricity consumption this year, and measures such as power rationing and power reduction have been introduced in an orderly manner. As a large electricity consumer, the factory has prominent contradictions in power supply, protection, and demand. In this context, rational allocation of factory energy storage systems can effectively alleviate peak power demand pressure, improve power supply and demand, promote new energy consumption, and achieve peak-valley arbitrage.
What is an industrial energy storage system?
Industrial energy storage system refers to the energy storage and dispatching system applied in the industrial field. They are designed to solve energy supply problems in industrial processes, providing stable power and energy reserves to meet the needs of industrial equipment. Industrial energy storage power systems can use various energy storage technologies, such as battery energy storage, supercapacitors, compressed air energy storage and fuel cells.
Among them, battery energy storage is more common in industrial energy storage systems, and its characteristics include:
High energy density: Industrial batteries have high energy density and can store a large amount of electric energy to meet the high energy consumption requirements of industrial equipment.
High power output: Industrial batteries can provide high power output to meet the instantaneous high power requirements of industrial equipment.
Long life and durability: Industrial batteries typically have a long life and durability, allowing them to withstand frequent charge-discharge cycles and the harsh conditions found in industrial environments.
Scalability: The industrial battery energy storage system can be expanded and adjusted according to actual needs to adapt to industrial applications of different scales.
Industrial energy storage systems, such as industrial UPS systems, have a wide range of applications, including manufacturing, industrial and mining enterprises, logistics and transportation, and renewable energy grid integration. It is of great significance to improve energy utilization efficiency, reduce energy consumption costs, and enhance the stability and reliability of power systems.
Functions of Industrial Energy Storage Systems
Peak shaving and valley filling to improve the economy of electricity consumption; assisting traditional power systems and automatic generation control (AGC) devices to quickly respond to frequency and voltage regulation commands;
(AGC scheduling commands can be completed within 1 second, which is nearly 60 times faster than the response speed of thermal power units);
Solve the grid stability problems caused by large-scale renewable energy grid integration and ensure performance;
Reduce the impact of load on the grid and improve the friendliness of load to the grid;
Compensate grid voltage and frequency deviation to improve load power supply quality.
At present, the industry's profit model mainly relies on peak-valley arbitrage, that is, charging at low electricity prices during low valleys and discharging at high electricity prices during peak hours. China is gradually improving the time-of-use electricity price. In some provinces such as Guangdong and Zhejiang, charging and discharging can be realized twice a day, which speeds up the investment recovery period of industrial energy storage. Industrial energy storage can also be used in conjunction with photovoltaics. When there is excess photovoltaic power generation that cannot be consumed by the industry, it can be stored in the energy storage system. When the photovoltaic power generation is insufficient, the stored power can be released for use, thereby increasing the penetration rate of clean energy and saving electricity costs for industry and commerce. In addition to the above points, industrial energy storage systems can also serve as backup power sources. We know that there may be power shortages in some areas in summer, and the energy storage system can provide power for the main load and deal with sudden power outages, reducing the investment cost of UPS power supply equipment in the industry.
