Automatic Power Generation Control

This work deals with the automatic power generation control considering generator rate constraints by using thermal systems with combination of the automatic voltage control and market based deregulated system. The main purpose of the AGC is to balance the total system generation against system load and losses so that the desired frequency and power interchange with neighboring systems are maintained. Any mismatch between generation and demand causes the system frequency to deviate from scheduled value. Thus high frequency deviation may lead to system collapse. Power system operation at a lower frequency affects the quality of power supply and not allowed. Many investigations in the field of automatic generation control of interconnected power system have been reported over the past few decades. Investigation regarding to the AGC of interconnected thermal system is limited to the selection of controller parameter and effect of GRC (generation rate constraints).In this thesis attempt is made to develop AGC scheme is employed with AVR and market structure. Here coupling between AGC and AVR scheme is employed.
