Decentralized Voltage Control in active MV Distribution Networks

A decentralized voltage control strategy for MV distribution networks is here proposed, which is based on the possibility at any specific node to locally estimate the voltage level variations at the neighbouring nodes through the real-time measure of the current flowing on the incoming and outgoing lines. This enables to develop voltage control strategies accounting for 3 adjacent buses although based solely on local measurements. This approach is demonstrated to improve the overall network performance while limiting the need of large investments on communication systems.
