Decentralized autonomous object-oriented EMS/SCADA system

Energy management systems/supervisory control and data acquisition (EMS/SCADA) systems are usually geographically distributed and have operational organizations. They are changing in accordance with the various and varying environments, and they should be flexible enough to adapt to those changes quickly. The paper proposes a new architecture called SCOPE (System Configuration of Power Control System) to realize flexible and reliable EMS/SCADA systems. SCOPE makes application programs independent of the operational organization and system configuration of the EMS/SCADA system, i.e., application programs are not influenced by changes in them. These properties make EMS/SCADA systems flexible and reliable, and also the development of EMS/SCADA systems becomes efficient and economical. Through developing and evaluating a SCOPE prototype system, it has been confirmed that the flexibility and maintainability of EMS/SCADA systems based on the SCOPE architecture has been improved
