Power distribution network CPS evaluation method for electric power-traffic-information system interaction influence

Abstract

The invention discloses a power distribution network CPS evaluation method for power traffic information system interaction influence. The method comprises the following steps: step (1), dividing reliability parameters of a current input physical element and an information element to determine a current distribution network physical system state and a current distribution network information system state, (2) calculating a user travel according to the determined traffic system state and traffic information system state, (3) determining an electric vehicle charging plan according to the state of the power grid information system at the network access moment, (4) determining an isolation area and the power failure duration of each load point based on the FLISR event tree model, (5) updatingan information system adjacency matrix according to the state of the information element under the current system clock, and (6), counting reliability indexes of all the load points, judging whether simulation time is up or not, meeting the reliability indexes of the output system are met, otherwise, executing the step 2 again. The interaction effect between the power traffic information systems is fully considered, and the reliability of the power system is accurately evaluated.

Description

technical field [0001] The invention belongs to a method for improving the performance of a distribution network, in particular to a distribution network CPS evaluation method for the interactive influence of electric power-traffic-information systems. Background technique [0002] Electric energy is an important resource related to the national economy and the people's livelihood. The reliability of the power system reflects the degree to which the power industry meets the power demand of the national economy. It is of great significance to effectively evaluate the reliability of the power system. Power system reliability assessment methods mainly include analytical method and simulation method. Both methods calculate system reliability indicators based on probability statistics. According to different calculation principles, the two methods are applicable to different scenarios. The analytical method is suitable for the reliability evaluation of a relatively simple system ...
