The increase in the number of factors affecting the power grid has led to the rapid change of the parameters describing the power grid simulation, which in turn has led to more diversified and complex computing scenarios. As the most important supporting technology for the power system, power grid simulation must adapt to the new form requirements and quickly respond to the diversified power grid analysis technology support requirements.

[0003] In the development of core simulation computing modules of power system simulation, modules such as power flow calculation, electromechanical transient stability calculation, voltage stability calculation, and small disturbance stability calculation, represented by BPA and PSASP, have been continuously improved and expanded as the scale of the power grid continues to increase and the types of equipment modeling continue to increase, making great progress in many aspects such as power grid processing scale, complexity, platform adaptability, computing efficiency, and application forms.

There is an urgent need to use computer means to quickly complete repetitive and routine tasks in multiple scenarios in terms of automatic splicing of simulation data, automatic analysis of simulation, automatic judgment of simulation, and automatic decision-making of simulation. However, due to multiple constraints such as application purpose, technical design level, application level of related technologies, economic interests, software life cycle control, and mastery of core technologies, functional migration is difficult, and the research and development of power grid simulation applications relative to demand presents many problems such as slow response and difficulty in reusing mature functions. Although there are a large number of basic power grid simulation systems in the existing technology, many basic power grid simulation systems are difficult to flexibly respond to the changing needs of users, and there are shortcomings such as repeated development of functions and a large waste of resources. Summary of the invention
