In order to improve the stability of power grid operation, it is necessary to build a stable and reliable power grid dispatching system, and an active-active dispatching system considering the characteristics of parallel systems is proposed. By building two data centers, active and standby, we usually adjust between active and standby according to the application business volume to realize the full utilization of resources. In the event of a failure, another functioning center will take on all the business. And the parallel system is regarded as the virtual operation system of the power grid, and the active-active dispatching system of the power grid is obtained after combining the real and virtual systems, with functions such as management and control module, experiment and evaluation module, and learning and training module. The system calculates the power distribution results by initializing the data, establishes a two-layer task dispatching model, and solves the model using genetic algorithm, thus realizing the optimized dispatching of the active-active dispatching system. Experimental tests are conducted on the system, and the test results show that the method proposed in the system designed in this paper takes short time to reach the optimal allocation value, is highly efficient, has a large total amount of grid information dispatched, has strong dispatching capability, and has high security of dispatching information. It shows that the designed active-active dispatching system is feasible and conducive to the optimal dispatching of regional power grids.
