Hybrid Computing Hierarchy Based on-Line Analysis Service for Power Dispatching and Control System

Energy Internet is characterized by electricity as its core operation pattern, its stable and safe operation requires real-time and efficient online calculation and analysis to obtain operation status of the power grid. Under the centralized and unified dispatching cloud computing mode, the rapid increase of grid physical model and measurement data will inevitably affect the efficiency of online analysis service. Combining with concept of edge computing, this paper firstly designed the architecture of hybrid dispatching cloud and dispatching data network based online computing process was built. Through performing necessary data calculation and analysis at the substation level or subordinate dispatching and control centers, it reduces the amount of data uploaded to the dispatching cloud center. Then the concept of service-oriented was used to design the service hierarchy and implement detailed online analysis services. Finally, power grid model data was used to verify performance of topology analysis and calculation process in the way of decomposition and coordination computing mode.
