A Proposal of Interior Structure of Quality Control Center in the Flexible, Reliable and Intelligent Electric Energy Delivery System (FRIENDS)

Abstract

As the world wide de-regulation in the electric power industry progresses, the basic structures of future power system should change drastically. Particularly, in the power distribution systems which are closest to the demand side in power system, more higher flexibility and higher reliability are requested. Flexible, Reliable and Intelligent Electric eNergy Delivery System (it is called a “FRIENDS”) which was proposed by the authors is a new concept for a future power distribution system. The FRIENDS will be able to realize flexibly various requests of power customers and power suppliers.
One of the most important characteristics of the FRIENDS is that a new power improvement facilities (to be referred to as the “Quality Control Centers (QCCs)”) are considered to install very closely to the customers. However, the interior structure, the control method and protection system of the QCC are not established yet. Therefore, this paper expresses many functions to be accomplished by QCC and proposes several concrete interior structures as main parts of QCC. Further, those characteristics are explained qualitatively in this paper.
