Abstract: It is usual for electric power systems to include the following components: a load , an electrical generator (which will commonly be a synchronous machine), a turbine and a governor in order to control the turbine. The load frequency control problem is about the frequency control in power systems that are supplied with energy from a power plant (thermoelectric, hydroelectric). Therefore, the first step in order to study this problem is to model each one of the components of the system. Several different models will be presented, mostly for the modelling of the electric generator, load and the turbine. The response of three types of turbines under three different control techniques will be presented and compared: integral control, pole placement and linear quadratic regulator.
