Automatic voltage-control relays and embedded generation

Abstract

This is the second of two articles discussing the use of automatic-voltage-control relays in electricity distribution networks. The first article covered the basic control of on-load tapchanging transformers, line-drop-compensation, parallel transformers, master-follower and true-circulating-current systems. This article builds on the first to cover negative-reactance compounding and, in particular its relationship with embedded generation.
