2008-01 Power system security assessment and control in the new context of liberalized electricity market
December 1-3, 2008


   Power systems have traditionally been operated based on a background of previously performed studies and on the experience of dispatcher operators. Such practice usually leads to conservative limits and cannot often comply with market requirements to fully exploit power system equipment, plants and facilities and with transparency criteria in case of conflicting decisions imposed by regulating bodies. On the other hand, the operator may have to face new operating conditions brought about by the restructured power market and may lack adequate experience to operate the system, the current trend being to operate power systems closer and closer to their limits. These considerations emphasise the need for accurate evaluation of security, performed on different phases of power system operation and in particular made available to the control room operator for on-line assessment and preventive action implementation.

The tremendous advances in computer science and technologies have permitted significant application of methodologies and tools made available to power system operator in EMS (Energy Management Systems) for Dynamic Security Assessment (DSA) that have been developed in the last decades and that have recently found the technical support and environment for on-line applications as proved by European Projects and by Industrial realizations.

The course approaches Security Assessment having in mind that power systems are critical infrastructures with challenging potential vulnerability issues to be fronted. It focuses on Energy Management System environment; Cyber Security; DSA functions like Transient Stability Assessment (TSA), Voltage Stability Assessment (VSA), use of Advanced Technologies. An overview and a detailed though synthetic presentation of analytical methods, technologies and experimentations are presented. The aim is to generate a basic although comprehensive knowledge of security assessment, preventive and corrective control problems, ICT technologies for potential attendees that are typically PhD students, researchers, junior transmission system operators.
