System analysis - development and operation

A main challenge in transmission system operation is to ensure optimal utilization of the existing power grid. Available transmission capacity is to a large extent determined from transfer limits on critical power transmission corridors. These transfer limits are usually determined from operational security considerations, taking into account critical contingencies and the risk of thermal overloads and stability problems.

SINTEF has developed prototype computer tools for probabilistic security assessment to be applied by transmission system operators in daily operation planning.Increased utilization of the transmission system is also a main objective in other important areas of research, which include power system modelling, stability analysis and control design.
