Energy management systems (EMS): use in emergency conditions

Power systems in emergency conditions are analized together with the control possibilities arising from the support of energy management systems. Main conditions include loss of generation in a power system and power deficit in industrial distribution systems. Use of EMS in data recording, processing and updating tables according to real-time conditions are then examined and interaction with load-shedding relay setting is proposed. Attention is also given to detection of sudden power flow changes, islanding in both types of systems and slow control of overloads through generation rescheduling and load-shedding.<
