Development of ICT (Information and Communication Technology) systems for power system operation and deregulated markets in a smart grid arena

摘要

ICT (Information and Communication Technology) systems have developed in a rapid pace.Fibre optic based communication systems have increased their capacity to a great number andthe node equipment has a technical life time of less than five years. At the same time, severalICT system users have outsourced the office systems.The purpose of this paper is to describe this development, mainly from the author’s 20 years’historical perspective of the years of 1990-2010. The development of the ICT systemspossesses a necessity for modern power system operation and market driven development in aforthcoming smart grid power arena. Here, new customer-oriented solutions of metering,connections of electric vehicles (EVs), and new SCADA (Supervisory Control And DataAcquisition) /EMS (Energy Management System) solutions become crucial. All these newsystem solutions require an improved cyber security design, which also will be stressed in thispaper. The paper ends with concluding remarks and future directions for the forthcomingsecure ICT systems.
