Abstract

This article proposes a voltage regulation scheme for distributed energy resource-connected distribution networks based on static synchronous compensator to compensate for both shortterm and long-term voltage sags. The proposed voltage regulation scheme provides a fast and precise control on the nodal voltage, with no need to load shedding, capacitor switching, transformers, or power management schemes. The principles supporting the proposed voltage regulation scheme are discussed and the effectiveness of the proposed control is demonstrated through time-domain simulation of a two-unit test distribution network in the PSCAD/EMTDC software environment.
