Process modelling for Load Frequency Control in power systems

Underlining first the principle of Load Frequency Control (LFC) according to the UCTE regulations this paper also presents simple continuous time models identified for the main hydro and thermal power generation units used by the LFC in Romanian Power System. Different models were proposed in previous articles but they are very complex for LFC studies. An experimental identification procedure based on deterministic methods with rectangular pulse sample signal is proposed to estimate the values of models parameters. These models can be used for tuning LFC systems as well as for building and setting up a real-time simulator for dispatcher training.
