AI Technical Summary

Problems solved by technology

Due to the maximum capacity limit of the line or transformer at the gateway, when the electrical power of the gateway exceeds this capacity, it may cause equipment damage

In the electricity market, the multi-energy system may sign a contract with an external power supply company that includes the upper limit of the maximum gateway electric power. If the actual gateway electric power exceeds the upper limit, the contract will be violated and additional fees will need to be paid
