This paper proposes a new architecture called SCOPE (System Configuration Of PowEr control system) for flexible supervisory control of power systems.Energy Management Systems / Supervisory Control and Data Acquisition (EMS/SCADA) systems are usually widely distributed and have hierarchical operational organizations.They are continuously changing in accordance with various requirements and environments.Therefore, they need to be flexible enough to quickly adapt to those changes.SCOPE classifies software for conventional electric power systems into three hierarchical layers, the Application dependent part, the Power system dependent part and the Computer system dependent part.The power system dependent part realizes flexibility for changing of power system equipment and operational organization by introducing a reduction relationship which enhances the generalize/specialize relationship of object oriented technology.SCOPE architecture enables EMS/SCADA systems to be flexible, and also enables efficient and economic development.It is confirmed through developing and evaluating a SCOPE prototype system that the flexibility of EMS/SCADA systems is improved. I N T R O D U C T I O NElectric power systems are being continuously expanded in accordance with growing consumer demands.New power stations, substations and transmission lines are being built year by year, and new functions are being introduced to improve power supply capability and reliability.The operational organization of power systems Permission to make digital or hard copies of all or part of this work for personal or classroom use is granted without fee provided that copies are not made or distributed for profit or commercial advantage and that copies bear this notice and the full citation on the first page.To copy otherwise, to republish, to post on servers or to redistribute to lists, requires prior specific permission and or fee.
