Intelligent Nodes in distribution systems - Transition from radial to meshed operation

Due to the deregulation of the electricity sector and simultaneously the growing interest in distributed generation, the uncertainty in operation and planning has increased for distribution network operators. To avoid uneconomic investments, flexible solutions are needed. For this, the concept of an Intelligent Node is proposed. This paper addresses one of its control aspects: the transition from supplying a radial feeder with loads into controlling the power flow in a meshed power system.
