Visual modeling method for simulation data of power distribution network cyber-physical system

Abstract

The invention relates to the field of electric power system simulation, in particular to a visual modeling method for the simulation data of a power distribution network cyber-physical system. The method comprises the following steps that: (1) determining an analysis target; (2) selecting an analysis angle; (3) constructing a data analysis and calculation model; (4) configuring an analysis resultdatabase; (5) constructing and configuring an analysis topic diagram; and (6) carrying out the visual displaying of analysis result data. By use of the method, the analysis modeling problem of a greatquantity of historical simulation data of the power distribution network cyber-physical system and the visual displaying problem of the analysis result are solved, the simulation data analysis of complex research contents, including the state evolution properties of the power distribution network cyber-physical system, the dynamic interaction influence of an information system and a physical power grid and the like under the function of multiple correlation events and the information system under a situation that the cascading failure of the power distribution network cyber-physical system isin the presence is realized, and therefore, complex and diversified simulation data analysis requirements under a power distribution network cyber-physical system environment can be met.

Description

technical field [0001] The invention relates to the field of power system simulation, in particular to a visualization modeling method for analyzing data of distribution network cyber-physical system simulation. Background technique [0002] During the rapid construction of the distribution network, with the continuous access of random, intermittent and fluctuating renewable energy, the popularization of intelligent flexible loads and electric vehicles, the continuous development of the "source-grid-load" flexible interactive operation mode With the increasing level of application, digitization and informatization, the interaction of energy flow and information flow in the distribution network is becoming more and more frequent, and the coupling degree of energy system and information system is getting closer. The "binary composite system" composed of physical systems is called cyber physical system (CPS). [0003] The core feature of distribution network CPS is the deep in...

Problems solved by technology

[0006] 1) The processing of simulation historical data in the prior art only displays these data in the form of graphs, curves, reports, etc. without in-depth calculation and analysis of the data. Therefore, it is impossible to understand power distribution in depth through the existing technology Intrinsic nature and interrelationship between simulation data and simulation results of cyber-physical system;

[0007] 2) Although the prior art provides common software analysis tool interfaces such as Excel, AutoCAD, and Matlab, there are two shortcomings: first, the method for using these tools to analyze the simulation historical data is not convenient enough; second, it cannot be customized The data analysis algorithm cannot configure the visual presentation of the analysis results

Therefore, the existing technology does not have the ability to analyze the simulation historical data of the complex research target of the distribution network cyber-physical system in a visual way
