Expert systems for power system operation

SCADA/EMS provides operators with the assistance required for the economic and reliable operation of electric power systems. Within this area a large number of programs have been developed to solve important control and monitoring problems. Other problems, especially complex tasks that need human expertise, remain unsolved. The increase of interactions and the sensitivity of modern energy systems to failures tend to overburden operators. New techniques have to be adopted to coordinate the data in order that a concise picture of the current operating state of the system may be presented at any time.
