Simulation Study of Load Frequency Control of Single and Two Area Systems

The load variation on a power system being unpredictable causes drifts in frequency and voltage from their nominal values resulting in loss of generation due to tripping of lines and even blackouts. Frequency and voltage drifts can be minimized and kept within tolerable limits by automatic generatio...

Description
Summary:The load variation on a power system being unpredictable causes drifts in frequency and voltage from their nominal values resulting in loss of generation due to tripping of lines and even blackouts. Frequency and voltage drifts can be minimized and kept within tolerable limits by automatic generation control. Automatic generation control of a system consists of two parts; load frequency control (LFC) and automatic voltage regulator (AVR). In this paper, a simulation study is carried out to understand the operation of load frequency controller by developing models in SIMULINK. The simulation study helps students to understand the principle and challenges behind load frequency controller.
