Distributed automation solution and voltage control in MV and LV distribution networks

Distributed generation and consequent voltage rise problem in MV distribution networks has been found to have similar effects in LV networks due to the worldwide growth of small-scale PV generation. Multiple strategies have been proposed to mitigate the voltage rise issues in order to increase hosting capacity of distributed generation in distribution networks. New solutions have to be found to better utilize available resources and information in active network management. This paper studies the operation of coordinated voltage control in MV and LV grids, and presents a proof-of-concept implementation of distributed automation architecture for coordinated voltage control in both networks in Real Time Digital Simulator environment
