Abstract

With the rapidly increasing penetration of distributed generation (DG), the hosting capacity of distribution networks has become a major concern. In this work, a Medium Voltage DC (MVDC) link between the island of Anglesey and the mainland in North Wales was analyzed to assess its effectiveness in increasing the hosting capacity of DG. Three control strategies of the MVDC link were proposed considering different control objectives: power loss minimization, line utilization balancing and voltage profile improvement. Performances of the distribution network with the MVDC link were analyzed considering these control strategies. Results illustrated that the MVDC link can significantly increase the network hosting capacity of DG compared to the original AC operation. The control strategy considering line utilization balancing as the objective resulted in more DG connection to the network than that of considering power loss minimization or voltage profile improvement as the control objective.
