Problems solved by technology

[0004] The information sharing of the existing microgrid system is low, and the power generation status, battery storage capacity, and load status of a single user cannot be fully fed back in time, resulting in low energy utilization in the microgrid system and poor economic benefits for users

In addition, due to the strong randomness of users in the construction of the micro-grid system, the traditional optical cable communication method needs to lay cables separately, which is difficult to operate and expensive, which restricts the construction of the micro-grid system and the optimization of system quality.

[0005] The traditional micro-grid structure requires each user in the system to be connected to the central router, and the central energy router performs distribution and energy scheduling. This structure has advantages for the optimization of communication and energy in the system, but in the actual environment, the power line Structure construction, new users do not choose the nearest grid bus but connect to the central controller, which will bring a huge burden to the grid system and greatly increase the cost
