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 was proposed. By building two data centers, active and standby. According to the application business volume, adjustments were made between the primary and backup adjustments, achieving full utilization of resources. In the event of a failure, another functioning center will take on all the business. The parallel system was regarded as the virtual operation system of the power grid, and the active-active dispatching system of the power grid was 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. By initializing the data, calculating the power distribution results, establishing a two-layer task scheduling model, and using genetic algorithms to solve the model, the optimization scheduling of the dual active scheduling system can be achieved. The test results show that the method proposed has the advantages of short time, high efficiency, large total amount of grid information dispatching, strong dispatching ability and high security of dispatching information to reach the optimal distribution value. It shows that the designed active-active dispatching system is feasible and beneficial to the optimal dispatching of regional power grid.
