A Basic Study on the Functions of Power Delivery Network in the Flexible, Reliable and Intelligent Electric Energy Delivery System (FRIENDS)

Abstract

The authors have proposed Flexible, Reliable, and Intelligent Electric eNergy Delivery System (FRIENDS) as a form of the future power delivery systems. The main idea of FRIENDS is to install Quality Control Centers (QCCs) in the vicinity of customers. These QCCs make a new power delivery network below power substations. Circuit breakers or switches using power electronics devices are also installed in the power delivery network so as to change the network configuration according to the system condition or the fault situation.
This paper investigates some functions of the network using solid state switches. In order to protect these switches, it is also examined the installation of current limiting devices to the network in FRIENDS.
