doi:10.11930/j.issn.1004-9649.201910118

Abstract

Abstract: In order to study the impact of dispersed wind farm (DWF) integration on distribution network in different scenarios, a simulation model is established for the distribution network with DWFs, and a comparative analysis is made. Firstly, based on the basic model of distribution network, the paper analyzes the impact mechanism of DWF access on node voltage, power flow distribution and network loss. Then, based on a case of a distribution network in China Southern Power Grid, the paper studies the impacts of DWF access with different penetration rates on the distribution network in different scenarios. Finally, according to the simulation results, the paper summarizes the impact of dispersed wind power access on the distribution network. The general law of voltage and network loss distribution in distribution network is obtained under different access location, access capacity and access form of DWFs. The simulation results show that different access modes of DWFs, including accessing at the head, middle and end terminals of distribution network feeder, or access of single or multiple wind farms, have different impacts on voltage and network loss distributions. It is therefore important in practice to reasonably determine the access capacity and location of DWFs.

Key words: dispersed wind farm (DWF), distributed network, penetration rate, voltage distribution, network loss
