Application of 100KWH energy storage system in industrial and commercial fields
With the transformation of global energy structure and the rapid development of renewable energy, energy storage system is receiving more and more attention as a key technology to balance supply and demand and improve energy utilization efficiency. Especially in the industrial and commercial fields, 100KWH energy storage system has become a hot spot in the energy storage market due to its moderate energy storage capacity and flexible application scenarios.
1. Technical Scenarios
According to the technical solution of 100KWH energy storage system released by BSLBATT, the system mainly consists of energy storage converter PCS and lithium iron phosphate battery pack. Among them, the PCS is a 50kW off-grid bidirectional energy storage converter, which is connected to the grid through a 0.4KV AC bus to realize the bidirectional flow of energy. The battery pack consists of 10 51.2V 205Ah batteries connected in series, with a total voltage of 512V and a capacity of 205Ah. This configuration not only provides sufficient energy storage capacity, but also ensures the stability and safety of the system.
2. Application Scenarios
In industrial parks, energy storage systems can be used as single-scene or multi-scene solutions. For example, the energy storage systems provided by Dazhong Digital Energy, including liquid-cooled integrated units and optical storage integrated units, can support a maximum of 10 units connected in parallel and provide energy storage capacities ranging from 100kW/232kWh to 5MWh. These products can not only meet the energy demand of industrial parks, but also realize the visualization and real-time monitoring of energy storage and safety through the intelligent energy storage management cloud platform.
3. Technical progress
In terms of energy storage technology, physical energy storage and thermal storage technology has made significant progress in recent years. For example, commercialization projects of compressed air energy storage (CAES) technology in China are advancing rapidly. Flywheel energy storage technology is particularly suitable for frequency regulation and short-time energy balancing of power systems due to its advantages of high power density, long service life and fast response speed. In addition, liquid flow battery energy storage technology is also evolving to provide an efficient energy storage solution.
4. Market Analysis
According to China Energy Storage Technology Research Progress 2022, the research and application of energy storage technology is developing rapidly. Energy storage systems are widely used on the power supply side, grid side and user side. On the user side, industrial and commercial energy storage mainly focuses on reducing the cost of electricity and guaranteeing the continuity of production.The new domestic installed capacity of new energy storage reaches 7.35GW in 2022, with a year-on-year growth rate as high as 200.35%, showing the explosive growth of energy storage market demand.
5. Investment and Operation Program
For industrial and commercial energy storage projects, there are various investment and operation modes. For example, owner-invested mode, financial leasing + contract energy management mode. These modes require that power-using enterprises can withstand a certain amount of cash flow and management pressure, but can obtain the maximum return. Meanwhile, with the improvement of time-sharing tariff policy and electricity spot market, the economy of industrial and commercial energy storage projects has been further guaranteed.
In summary, the application of 100KWH energy storage system in the industrial and commercial fields has a broad prospect, which can not only improve the efficiency of energy utilization, but also bring economic benefits to enterprises. With the continuous progress of technology and policy support, the energy storage market is expected to continue to maintain rapid growth.
