Active power distribution network power supply area division method and apparatus thereof

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.

Problems solved by technology

In order to ensure that the calculation time meets the requirements, the traditional algorithm is only suitable for small-scale power supply area division; the artificial intelligence method has made new progress in the work of power supply area, but the single use of intelligent optimization algorithm has slow convergence speed and poor optimization ability. Poor, premature convergence and other deficiencies

The addition of distributed power sources makes the structure of the distribution network more complex, so it is necessary to explore a fast and efficient method suitable for the division of power supply areas in complex active distribution networks, simplify the structure of the distribution network, and improve the quality of the distribution network. Economical and reliable operation
