Control of Power Systems

Lecturer:

Tutor:

Supervisor:

Department of Electroenergetics

Synopsis:

The subject deals with basic problems of power system control. First student obtains brief overview about problems of power system evolution, open market and international cooperation. More detailed attention is paid to technical problems of power system control, object functions of system control and methods of optimization, static and dynamics characteristic of the system, control of active and reactive powers, optimal power flow, unit commitment and load curve covering. Subject finishes by dispatch, system and subsidiary services overview.
