Distributed Generation Control via Ripple Signaling for Establishment of Ancillary Services in Distribution Networks

This paper presents the methodology and describes the technology requirements for exploiting ripple signalling to control Distributed Generation (DG) in the Distribution Network. A part of the Greek distribution network with increased penetration of PV power plants is simulated, with and without ripple signalling control, for various operational scenarios. The results of the simulation scenarios indicate the PV plants were the ripple signalling control should be applied. The results also highlight the ancillary services of the proposed methodology for the network, such as the improvement of the voltage profile and of other power quality indices along the feeders. The first tests of the actual system on the real line are also demonstrated, showing also that the new method is highly reliable, inherently cyber-secure and data-privacy protective.
