  The increasing penetration of distributed energy resources (DERs) creates new
voltage issues in distribution networks. This study proposes an algorithm that
mitigates these issues, by actively managing the active and reactive power of
those DERs. The control problem is formulated as an optimisation problem. The
study proposes solving the problem in a fully distributed manner and presents a
methodology to convert a centralised constraint optimisation problem into a
fully distributed constraint optimisation problem based on dual decomposition,
linearised model of the distribution network and peer-to-peer communication
protocol. A real low voltage residential semi-urban feeder from the region of
Flanders, Belgium has been used as a case study. The simulation results show
the ability of the proposed peer-to-peer control algorithm to control the
voltage effectively within limits.
