On the impact of using public network communication infrastructure for voltage control coordination in smart grid scenario

Abstract

This paper focuses on the impact of using the existing public network communication infrastructure for online voltage control support and coordination of renewable generation (ReGen) plants in medium voltage distribution systems. The communication network infrastructure and related communication protocols have introduced several test scenarios and cases that are evaluated with respect to the related latencies and validity of the signals being exchanged between a control center and the ReGen plants. An exemplary benchmark grid area in Denmark, including flexible ReGen plants, is used as a base case for evaluating the network performance in terms of latency. The main outcome of this study is to provide a generic overview of the aspects and their effects related to the use of existing public network communication infrastructure for online coordination of voltage control in a distributed system, considering the huge ReGen penetration, in order to ensure a resilient voltage controlled distributed systems.
