Overview of voltage control strategies in medium voltage networks with implementation of distributed generation

Abstract

The traditional voltage control in medium voltage networks no longer suffices with the increasing penetration of DG units. This paper will give an overview of possible voltage control strategies for medium voltage networks aiming to maximize the production of renewable energy. Simulations and case studies will be conducted to examine these control strategies and to compare them to the traditional voltage control in medium voltage networks. In this overview, active power curtailment, reactive voltage control and control strategies using the OLTC will be examined. (6 pages)
