Usually Energy Management Systems/Supervisory Control and Data Acquisition (EMS/SCADA)systems are geographically distributed and have hierarchical operational organizations. They are continuously changing in accordance with the various and varying environments, and they should be flexible enough to adopt to those changes quickly. This 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 operational organization and system configuration of EMS/SCADA system, i.e., application programs are not influenced by changes in them. By these properties, EMS/SCADA systems become flexible and reliable, and also development of EMS/SCADA systems become 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 SCOPE architecture had been improved.
