The integration of distributed generation and electric vehicles’ chargers into the electricity grid are two great challenges for distribution networks operators worldwide. In these cases, a reliable and cost-effective communication and control system is needed, in order to ensure stable operation of the grid and keep the power quality indices inside their limits. Such a control system is already in use by most of the distribution networks operators: the ripple signaling system. In this study, a part of a distribution network with increased penetration of Photovoltaic (PV) power plants is simulated, with and without ripple signaling con-trol, for various operational scenarios. The results of the simulation scenarios indicate those PV plants where the ripple signaling control should be applied. The results also highlight the type of ancillary services that the proposed methodology can supply to the network, such as the improvement of the voltage profile and other power quality indices along with 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.
