Dynamic Variance Equalization Planning Optimization Method for Power Grid System Protection Communication Network

To improve the universality of the backbone communication network architecture model in Smart Grid, this paper proposed a dynamic variance equilibrium planning optimization method for the system protection service in the power grid. Firstly, based on the two-layer architecture model of the power backbone communication network, a network equilibrium optimization model is constructed. Secondly, based on the network equilibrium optimization model, a simulation experiment method with the node usage ratio as the optimization target and the delay in the transmission process as the constraint condition is designed. Finally, the model was quantified through simulation experiments. The simulation results show that the proposed optimization model has excellent applicability in network balance planning of grid protection services.
