Hotspot Engine Program Industrial and commercial users often face severe challenges in transformer loads during peak hours, which is not only related to the stable operation of equipment, but also directly related to the production cost of enterprises. In the calculation of electricity charges of the State Grid and China Southern Power Grid, industrial and commercial users need to pay for transformer capacity and actual electricity consumption, which makes transformer capacity expansion an expensive and necessary investment. However, by introducing new energy storage systems, we can provide these users with a cost-effective solution. 
The energy storage system can provide stable power support for the plant during peak hours, thereby significantly reducing the high cost caused by transformer expansion. Take a specific case as an example, suppose a company has a transformer capacity of 1000kVA and a stable load of 700kw, but after the production scale is expanded, it needs to increase the electrical load by 300kw. According to traditional calculations, this would result in a spike in transformer capacity demand that would exceed the original rated load, necessitating capacity expansion. However, by introducing an energy storage system, we can recalculate the maximum capacity requirement of the transformer. When the discharge power of the energy storage system is 500kw, the power factor is 0At 9 o'clock, we can find that during the peak period of electricity consumption, the actual demand capacity of the transformer is reduced to 7778kVA, which is much lower than the original 1000kVA transformer capacity. This means that by rationally configuring the energy storage system, we can effectively avoid the expansion and transformation of transformers, thereby saving a lot of costs for enterprises. 
This solution is not only economical, but also technically feasible. As a grid-connected AC power source, the energy storage system can stably provide the required power support and ensure the normal production and operation of the enterprise. Therefore, for industrial and commercial users, the introduction of new energy storage systems is not only a viable option, but also a wise investment.
