Network integrated supervisory control for power systems based on distributed objects

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.
