Data filtering method and system for active power distribution network

Abstract

The invention discloses a data filtering method and system for an active power distribution network. The method comprises the steps that active power distribution network data is cleaned; property reduction is performed on the cleaned active power distribution network data, and training data and to-be-filtered data containing condition properties in a minimum relative property set after reductionare determined and obtained; classified filtering is performed on the to-be-filtered data obtained after reduction, a genetic expression algorithm is utilized to perform data mining on the training data, and a classification function relation between the condition properties and known sensitive properties is obtained; and the condition properties in the to-be-filtered data are substituted into theobtained classification function relation, a function actual value is obtained through calculation, whether the properties are sensitive properties is judged according to the calculated function actual value, and sensitive data with the sensitive properties is filtered out. Through the data filtering method and system, classified filtering can be performed on all kinds of service sensitive data of the active power distribution network, so that proactive protection is performed on the sensitive data, and a data transmission problem of the active power distribution network is solved.

Description

technical field [0001] The invention relates to a data filtering method and system for an active distribution network, belonging to the technical field of electric power information transmission. Background technique [0002] As an important part of the power system, the distribution network is one of the core contents of the smart grid construction. Especially in recent years, with the widespread access of multiple distributed equipment components (such as microgrids, charging piles, etc.) units such as large-scale distributed energy, energy storage, and flexible loads, the distribution network is moving towards active distribution networks direction development. Compared with the traditional distribution network, the composition of the active distribution network and the interaction between the source network and the load are more frequent and complex. [0003] With the development of the economy and the progress of science and technology, the active distribution network...
