ABSTRACT

Real-time grid management is critical in ensuring safe, reliable, and optimized operation of the utility grid. For real-time grid management systems, one of the key trends in the industry is the increase of bandwidth from the substation to the control center and from the monitoring and control points on the distribution network to the control center. The primary purpose of an electric utility supervisory control and data acquisition (SCADA) system is to acquire and monitor real-time data from the grid. A power system simulator is used as a look-ahead engine to forecast immediate future conditions. This look-ahead data, together with traditional energy management system (EMS) SCADA and state estimator data, are shown at the operator workstations to facilitate and improve timely, preventive decision-making. Control center is a general term for a centralized location where the utility grid is monitored and controlled remotely.
