Embodiment

[0023] Example: see attached Figure 1-5 , the present invention provides a technical solution: a method for assessing the vulnerability of an electrical integrated energy system, which includes the following steps:

[0024] S1: start evaluation;

[0025] S2: Calculating and inputting the estimate of the possibility of branch removal of the transmission line;

[0026] S3: Calculating and inputting the estimate of the possibility of branch removal caused by natural disasters;

[0027] S4: Calculate and input the estimated possibility of branch removal caused by internal structure, technology and equipment factors;

[0028] S5: Calculating and inputting the estimated possibility of transformer branch removal;

[0029] S6: Get the assessment value of the vulnerability of the electrical integrated energy system.

[0030] In this embodiment, the possible factors of the transmission line branch cut include branch cut caused by special line structure, branch cut caused by relay p...

Abstract

The invention discloses a vulnerability assessment method for an electrical integrated energy system. The vulnerability assessment method comprises the following steps: S1, starting assessment; S2, calculating and inputting an estimated value of the branch removal possibility of the power transmission line; S3, calculating and inputting a branch removal possibility estimated value caused by the natural disaster; S4, calculating an estimated value of the possibility of branch removal caused by internal structure, technology and equipment factors, and inputting the estimated value; S5, calculating and inputting a transformer branch removal possibility estimated value; and S6, obtaining an evaluation value of the vulnerability of the electrical integrated energy system. According to the electric power system structure vulnerability analysis method based on the electrical betweenness and the risk theory, the effectiveness of identifying the vulnerable branches and the vulnerable nodes in system structure vulnerability evaluation by the electrical betweenness is verified.

Description

technical field [0001] The invention relates to the field of vulnerability assessment methods for electrical comprehensive energy systems, in particular to a vulnerability assessment method for electrical comprehensive energy systems. Background technique [0002] By coupling various forms of energy, the electrical integrated energy system can not only realize the cascade utilization of energy, but also effectively solve the problems of energy depletion and environmental pollution, and has a good development prospect; however, in terms of ensuring the stable operation of the integrated energy system, There are still many problems and challenges. [0003] With the development of power system security risk analysis methods, people began to introduce the concept of vulnerability into the power system, trying to find out the weak links of the power system, and take corresponding preventive measures to improve the operation status of the system and prevent large-scale blackout ac...
