Embodiment Construction

[0052] The present invention will be further described below in conjunction with the accompanying drawings.

[0053] The present invention mainly focuses on the fact that the computing resources for the current power system security and stability analysis and calculation still adopt a fixed configuration mode, especially for the calculation of trigger operation, the number of application functions it runs and the number of calculation tasks contained in each application function are random, The fixed allocation of computing resources will cause idle and waste of computing resources. Therefore, it is necessary to consider dynamically estimating the number of computing resources required according to computing requests. On the one hand, it can complete the security and stability analysis and calculation within a specified time. utilization efficiency.

[0054] Based on the above considerations, the basic principle of the method of the present invention is: the application funct...

Abstract

The invention discloses a power system safety and stability analysis and calculation resource demand estimation method and system, which are applied to calculation resource estimation of power systemsafety and stability analysis and calculation. The method includes: dividing the application functions needing to be executed into a plurality of stages according to the execution dependency relationship between the application functions contained in each calculation request; respectively estimating the predicted calculation time and the minimum number of calculation resource standard units of each calculation stage based on the safety and stability analysis of a power system and the average execution time of a single calculation task of each application function on a calculation resource standard unit; and on the basis, further estimating the number of computing resource standard units and the estimated total execution time meeting the requirement of the specified total computing time ofthe computing request, thereby realizing the dynamic estimation of the security and stability analysis computing resources of the power system and promoting the global sharing and efficient utilization of the computing resources.

Description

technical field [0001] The invention relates to a power system security and stability analysis calculation resource demand estimation method and system, and belongs to the technical field of power system scheduling automation. Background technique [0002] At present, power system safety and stability analysis includes functions such as static safety analysis, short-circuit current analysis, electromechanical transient stability analysis, small disturbance dynamic stability analysis, static stability analysis, static voltage stability analysis, and frequency stability analysis. Fixed cycle operation and triggered operation. [0003] For safety and stability analysis applications that need to complete a large number of expected faults, including transient, dynamic and static safety analysis calculations, computer clusters are generally used to implement parallel calculations of multiple application functions and multiple calculation tasks to improve calculation speed.
