Method for fusion reconstruction and interaction of intelligent power distribution network big data

Abstract

The invention discloses a method for fusion reconstruction and interaction of intelligent power distribution network big data. The method is characterized by comprising the steps that (1) division of initial clusters is conducted on the intelligent power distribution network big data, an association rule is established according to the operating state of an intelligent power distribution network, and division of extended clusters is achieved; (2) current data are allocated to the initial clusters based on historical data, the operating state is predicted on the basis of the association rule, so that a self-healing control strategy is determined, and panoramic risk management and control and self-healing control are conducted. According to the method, division of the initial clusters is conducted according to the grid density, division of the extended clusters is conducted through establishment of the association rule, fusion reconstruction and interaction of the intelligent power distribution network big data are achieved, cluster efficiency and cluster accuracy of data streams are effectively improved, and the method has good extensibility and achieves system integration between panoramic risk management and control and self-healing control of the intelligent power distribution network. When the method for fusion reconstruction and interaction of the intelligent power distribution network big data is applied, the intelligent control level of the power distribution network can be improved, and the self-healing control function of the power distribution network is enhanced.

Description

technical field [0001] The invention belongs to the research field of panoramic risk control and self-healing technology for big data-oriented intelligent distribution network, and relates to a big data fusion reconstruction and interaction method of intelligent distribution network. Background technique [0002] The distribution network covers population gathering places, modern industries and commercial centers. The power load density is high, the power supply path is short, the coordination of relay protection is difficult, and the distribution line is close to the operating limit. Once an emergency occurs, the entire power distribution will be affected. Normal power supply of grid power loads. With the access of a large number of distributed power sources / micro-grids / energy storage devices, the scale of the distribution network is becoming larger and larger, the structure is becoming more and more complex, and its operating characteristics and control characteristics are...
