The benefits of looping a radial distribution system with a power flow controller

In this paper the benefits of looping the conventional radial distribution system by a series power electronic system to control power flow has been investigated. The conventional radial electrical distribution system will change to loop or even meshed system due to the deregulation of electrical system and connection of Distributed Generation to Medium and Low voltage in future. However looping the feeders in the conventional distribution system has some benefits which are discussed more precisely in this paper. Controlling the power flow between two feeders from different substation by placing a D-SSSC in the connection point will be source of many advantages. These advantages will be voltage regulation, increasing reliability, loss reduction, avoiding congestion in cables and facilitating use of distributed generation. The real data of Tehran electrical distribution network is used as case study to investigate the advantages of looped power flow controller versus conventional radial distribution system.
