Abstract:

With the rapid development of the number and scale of microgrid and distributed energy, the current system can not satisfy the requirements of massive related data acquisition, storage, analysis and calculation. In order to meet the processing requirements of high concurrency and high reliability of multi-microgrid control, this paper proposes a microgrid automatic control system based on cloud edge collaboration. Cloud edge computing resources is optimized based on Docker container technology. The structure of microgrid automatic control system is designed based on cloud edge collaboration. And the cloud edge collaboration function and main data flow are described in detail. The core functions such as microgrid control and energy management and their data processing requirements are further analyzed. A computational analysis task scheduling strategy under cloud edge collaborative architecture is proposed. The migration task data flow is scheduled based on bandwidth resources, taking into account the task time limit requirements and server load balance. Finally, the validity of the function and superiority of the proposed microgrid automatic control system is verified by an operational example. The proposed system meets the control requirements of multi-micro-grid through the cloud edge collaboration with proposed structure, function and task scheduling strategy.
