Problems solved by technology
[0002] At present, in the process of power dispatching, there is a lack of post-event auxiliary decision-making methods for the control of power section cross-limits. The reasons mainly include two aspects. The method and the unit plan reduce the probability of cross-section limit; secondly, due to the complex operation rules of the power system, the relationship between various adjustment methods of power grid dispatchers and multiple control targets is complicated, and there is also a coupling relationship between sections. The adjustment of a unit may affect multiple sections, and the best adjustment strategy cannot be accurately analyzed only by manual experience

The present invention provides an analysis and decision-making method and system for power grid stability section control, starting from the follow-up link, and solving the current situation of lack of evaluation means for power section over-limit control efficiency. It includes: obtaining the data of the power grid model and operation mode within the analysis period; and calculating the optimal adjustment strategy, using the optimal adjustment strategy as an analysis reference standard. Starting from the post-mortem, the optimal adjustment strategy is obtained through the post-ideal re-scheduling, and the actual control strategy of the power dispatcher is analyzed and assisted in decision-making, which will help the power dispatcher to discover the deficiencies in the actual dispatching process and promote the subsequent scheduling of production. Continuous improvement can effectively guide the development of relevant analysis software and improve the safety and reliability of the power dispatching production process.
Description
technical field [0001] The invention relates to the field of power system operation and analysis, in particular to an analysis and decision-making method and system for grid stability section control. Background technique [0002] At present, in the process of power dispatching, there is a lack of post-event auxiliary decision-making methods for the control of power section cross-limits. method and unit plan to reduce the probability of cross-section limit; secondly, due to the complex operation rules of the power system, the relationship between various adjustment methods of power grid dispatchers and multiple control targets is complicated, and there is also a coupling relationship between sections. The adjustment of a unit may affect multiple sections, and the best adjustment strategy cannot be accurately analyzed only by manual experience. Contents of the invention [0003] In view of this, the embodiment of the present invention provides an analysis and decision-maki...
