Abstract

The invention relates to an active power distribution network analysis and evaluation system. The active power distribution network analysis and evaluation system is characterized by comprising a data acquisition module, a data maintenance module, a data verification and correction module, a power distribution network assessment module and an assessment result output module, wherein the data acquisition module is used for acquiring data of a power distribution network and transmitting the data to the data maintenance module; the data maintenance module is used for maintaining and upgrading the received data and then transmitting the data to the data verification and correction module; the data verification and correction module is used for carrying out data table, topological data and electric verification and correction on the received data and then transmitting the data to the power distribution network assessment module; the power distribution network assessment module is used for assessing indexes in a basic power distribution network, a novel electrical load and a distributed power supply to obtain three assessment results and then carrying out weighted average on the results to obtain a comprehensive assessment value of the active power distribution network in a certain region; transmitting the three assessment results and the comprehensive assessment value to the assessment result output module; the assessment result output module is used for outputting the received results in a text and data table form.

Description

technical field [0001] The invention relates to a distribution network evaluation system, in particular to an active distribution network analysis and evaluation system. Background technique [0002] With the implementation of the national low-carbon economic development strategy, photovoltaic power generation, wind power and other distributed new energy power generation are developing rapidly, requiring the distribution network to improve its adaptability in terms of network structure construction, active power and reactive power adjustment; electric vehicles and energy storage devices The development of emerging loads such as loads will also put forward new requirements for the adaptability and development of the distribution network. The improvement of these capabilities lies in the fast, correct and reliable distribution network analysis and evaluation. Most of the active distribution network analysis and evaluation work in the existing technology relies on the general e...
