Abstract

The invention relates to an active power distribution network power supply area division method and an apparatus thereof. The method comprises the following steps of using a fuzzy clustering method to acquire an initial power supply subarea of a power distribution network; establishing a power supply area target function and a constraint condition; merging the initial power supply subarea and an initial power supply subarea which has a switch connection relationship with the initial power supply subarea into a combination subarea, and using the power supply area target function and the constraint condition to determine an area optimization scheme of the combination subarea; and according to the area optimization scheme of the combination subarea, determining an area optimization scheme of a power supply area. By using the technical scheme of the invention, a basic mode of subarea optimization and total assessment is adopted so that a reasonable network subarea structure is acquired; and switch operation of a network is simplified and operation efficiency of the power distribution network is increased.

Description

technical field [0001] The invention relates to the field of distribution network operation control, in particular to a method and device for dividing power supply areas of an active distribution network. Background technique [0002] Distribution network power supply area division is a key issue in distribution network planning, and its results directly affect the economy of distribution network operation and power supply reliability. Reasonable power supply configuration and network structure can ensure the reliability and quality of power supply of distribution network, reduce network loss, and are of great significance to realize the economy and reliability of distribution network operation. [0003] Aiming at the division of power supply areas of the distribution network, Zhang Xinchang and Zhang Xiangan published the article "Regional Control Division of Distribution Network Based on Generalized Nodes", from the perspective of better realizing the centralized different...
