Abstract

This paper presents a new voltage regulation system multi converter dynamic voltage restorer (MC-DVR), capable of simultaneous compensation for voltage in Multibus/multifeeder systems. In this configuration two voltage-source converters (VSC) exist. The system can be applied to adjacent feeders to compensate for supply-voltage on the main feeder and full compensation of supply-voltage imperfections on the other feeders. In the proposed configuration, all converters are connected back to back on the dc side and share a common dc-link capacitor. Therefore, power can be transferred from one feeder to adjacent feeders to compensate for sag. The performance of the MC-DVR as well as the adopted control algorithm is illustrated by simulation. The results obtained in MATLAB/SIMULINK on a two-bus/two-feeder system show the effectiveness of the proposed configuration.
