Multi-source data-based stepwise evaluation method for active distribution network operation status

Abstract

The method for evaluating the operating state of an active distribution network based on a multi-source data step-type dynamic fuzzy system, based on a multi-source data step-type dynamic fuzzy system, includes the following steps: Step 1, the distributed power layer based on the multi-source data of the active distribution network, Comprehensive evaluation strategy for the operation status of the network layer and the active control layer; step 2, use the method of step-type dynamic fuzzy system to evaluate the operation status of each feeder integrated system according to the operation status of each specific unit; step 3, according to the operation status of different feeder integrated systems Status, to evaluate the operating status of the entire active distribution network. The present invention comprehensively utilizes the multi-source data of the active distribution network through the step-type dynamic fuzzy system, so that the evaluation of the operation state of the active distribution network can be performed layer by layer 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...
