Abstract

The invention discloses a power grid multistage dispatching data integration method. The method comprises the following steps: S1, selecting benchmark section data, and self-adaptively acquiring external network data and internal network data which are matched with each other according to the characteristic attributes of the benchmark section data; S2, carrying out data treatment on the matched internal network data and the external network data; S3, carrying out topology analysis on the internal network data and the external network data, establishing an interconnection channel of the internal network and the external network, and respectively acquiring the flow and the equipment operation states of the cross sections of interconnection lines in the internal network data and the externalnetwork data; S4, splicing the internal network data and the external network data into a unified whole network computing data, carrying out power flow calculation, and generating a whole-network section flow data file; S5, carrying out safe and stable online analysis according to the whole-network section flow data file, and obtaining a whole-network safe and stable online analysis result. According to the method, the effectiveness and the practicability of the safety and stability analysis of the multi-stage scheduling data integration are comprehensively improved.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a method for integrating multi-level dispatching data of a power grid. Background technique [0002] With the construction of an integrated interconnected large power grid, the rapid development of UHV and high-voltage ring networks, the connection between power grid dispatching at all levels is becoming increasingly close, and higher requirements are placed on the collaboration and mutual support capabilities of multi-level regulation agencies. . At present, only the cross-sectional data of the local dispatching model is used for safety and stability analysis, and the results are often not accurate and practical. Power grid operation section data is the data basis for online analysis of power system security and stability. In order to improve the safety and stability of the power grid, the optimized and integrated section data can significantly improve the accuracy of pow...
