There are some differences between C&I energy storage and large storage in terms of scale, application scenarios, and technical requirements, but there are also some commonalities.
1. In terms of scale, industrial and commercial energy storage usually refers to energy storage systems used in industrial and commercial fields, which are relatively small in scale, which can be tens of kilowatt-hours to several megawatt-hours. Mass storage, on the other hand, refers to energy storage systems used in the power system, which are usually in the tens of megawatt hours to hundreds of megawatt hours, or even larger.
2. In terms of application scenarios, industrial and commercial energy storage is mainly used in energy management, electricity price optimization, backup power supply and emergency power supply in the industrial and commercial fields. The large storage is mainly used in the power system in the peak and valley electricity price regulation, power grid peak regulation and valley filling, frequency regulation and stabilization and other scenarios.
3. In terms of technical requirements, industrial and commercial energy storage usually has relatively high requirements for the power and energy density of energy storage systems, and requires high charging and discharging efficiency and fast response capabilities. However, large storage has relatively high requirements for the energy density of the energy storage system, which requires large energy storage capacity and long-term stable operation ability.
4. In terms of economy, due to the difference in scale, the industrial and commercial energy storage system is relatively small, so it can usually be distributed or integrated with the power station, which has high flexibility and adaptability. The large storage system needs to consider more economic factors, including construction costs, operation and maintenance costs, and benefits.
Although there are some differences between C&I energy storage and mass storage, there are some commonalities between the two, such as the need for efficient energy storage technology, reliable control systems, and suitable application scenarios. In addition, with the advancement of technology and the development of the market, the boundary between industrial and commercial energy storage and large storage may also become blurred, for example, in some large industrial enterprises, large-scale industrial and commercial energy storage systems can be built to meet their energy needs.
