Asynchronous iterative load flow calculation system based on grid middleware

The invention provides an asynchronous iterative load flow calculation system based on grid middleware. The asynchronous iterative load flow calculation system comprises a coordination layer system, a plurality of subsystems and grid middleware systems between the coordination layer system and each of the subsystems. Each of the grid middleware systems comprises a job management and coordination unit and a file transfer unit, wherein the job management and coordination unit is used for coordinating computational process initialization and file interaction for calculation among subsystems in a load flow calculation process, and the file transfer unit is used for achieving data file interaction produced between the coordination layer system and each of the subsystems in the load flow calculation process by utilizing file interactive interfaces based on Grid file transfer protocol (FTP). The asynchronous iterative load flow calculation system based on the grid middleware can construct a grid computing environment for asynchronous iterative load flow calculation based on a computer network system, therefore management and coordination of uniform computing tasks of each control center in a wide area distribution mode.
