Analysis and decision-making method and system for power grid stable section control

Abstract

The invention provides an analysis and decision-making method and system for power grid stable section control, and solves the current situation of lack of power section out-of-limit control efficiency evaluation means by starting from a subsequent link. The method comprises the steps of obtaining a power grid model and operation mode data in an analysis time period; and calculating an optimal adjustment strategy, and taking the optimal adjustment strategy as an analysis reference standard. Starting from the post-event link, an optimal adjustment strategy is obtained through post ideal rescheduling,the actual control strategy of the power dispatcher is analyzed and assists in decision making, the power dispatcher can find defects existing in the actual dispatching process, continuous improvement of subsequent dispatching production is promoted, then research and development of related analysis software can be effectively guided, and the safety and reliability of the power dispatching production process are improved.

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 power grid stable section control. Background technique [0002] At present, there is a lack of post-assisted decision-making methods for the control of power cross-section limits in the current power dispatching process. The main reasons include two aspects: First, the current power system dispatching operation management mode emphasizes the "pre-event" and "in-event" links, and optimizes system operation beforehand. The method and unit plan reduce the probability of cross-section limit violations; secondly, because the power system operation law is complex, the relationship between the various adjustment methods of the power grid dispatcher and multiple control targets is complicated, and there is also a coupling relationship between the section and the section. The adjustment of a unit may affect multiple secti...

[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
