In order to effectively improve the efficiency and reliability of power grid communication and promote the intelligent development of the power grid, a multi agent 5G communication terminal resource allocation method considering randomness has been proposed for the power grid. Considering the randomness factor, the Monte Carlo method is used to complete the random power flow calculation of the multi-agent 5G communication terminal of the power grid. On this basis, a multi-agent 5G communication terminal resource allocation model for the power grid is constructed, and a hybrid particle swarm optimization algorithm is used to solve the multi-agent 5G communication terminal resource allocation model for the power grid, achieving multi-agent 5G communication terminal resource allocation. The experimental results show that the proposed method has good resource allocation performance for multi-agent 5G communication terminals in the power grid, and can effectively improve resource allocation efficiency.

The differential protection of distribution network has good selectivity and quick action, but it is difficult to apply in areas where the laying rate of optical fiber is not high. The emergence of 5G communication technology with low delay and high reliability provides a new communication solution for the application of distribution network differential protection technology. However, the 5G distribution network differential protection has a large amount of differential current data in its application, which leads to the problem of large data flow and high cost of 5G communication terminals. This paper proposes a scheme of adding differential protection data compression transmission technology to the 5G terminal, which not only does not affect the differential protection service, but also saves the communication data flow, providing a reference for the wide application of 5G technology in differential protection in the future.
Differential protection of distribution network has high communication requirements for reliability, time delay and delay jitter. Theoretically 5G can meet these requirements. However, real network test results show that there are problems such as burst large delay and burst packet loss for differential protection based on the current 5G network, and deterministic capability of the current network is poor. This paper first gives the real network test results of differential protection based on 5G, and then gives a general description of deterministic technologies and the possible solution to meet the requirements of differential protection.
