Active power distribution network running state assessment method based on multi-source data stepped dynamic fuzzy system

Abstract

Provided is an active power distribution network running state assessment method based on a multi-source data stepped dynamic fuzzy system. Based on the multi-source data stepped dynamic fuzzy system,the method includes following steps: step 1, establishing a running state comprehensive assessment policy based on a distributed power layer, a network layer and an active control layer of multi-source data of an active power distribution network; step 2, assessing the running state of each feed line comprehensive system according to the running state of each specific unit by employing a steppeddynamic fuzzy system method; and step 3, assessing the running state of the whole active power distribution network according to the running state of each feed line comprehensive system. According tothe method, the multi-source data of the active power distribution network is employed in a comprehensive manner through the stepped dynamic fuzzy system so that the assessment of the running state ofthe active power distribution network can be performed in a layered manner and quantified layer by layer.

Description

technical field [0001] The invention belongs to the electric power system operation monitoring in the field of electric power technology, relates to the operation monitoring of the electric power system in which the state of electric equipment is uncertain and different network states coexist, and is an active distribution network operation state evaluation method based on a multi-source data step-type dynamic fuzzy system . Background technique [0002] In recent years, the depletion of traditional energy and the huge pollution caused by the use of traditional energy have made improving energy utilization efficiency and strengthening the use of renewable energy an inevitable choice to solve the contradictions between energy demand growth and energy shortage, energy utilization and environmental protection. As one of the cleanest and most efficient ways to utilize energy, distributed power generation technology utilizes various available dispersed energy sources for power ge...
