A Case Study on Load Frequency Control with Automatic Generation Control on a Two Area Network using MiPower

Abstract

This paper basically explains about the load frequency control in a multi area network. A two area network has been considered where frequency control is done using the Automatic Generation Control (AGC) system simulated in MiPower software. There are two case studies which have been explained, where the frequency behaviour has been shown under different loading conditions. In one case, the load increment was under the maximum generation limit and in the other case, it exceeded the maximum generation limit. Along with the case studies, the working of the AGC control system has also been explained in detail with its response for different loading conditions. The network has been simulated in MiPower from which the respective load flow studies results have been obtained. The AGC diagram has also been simulated in the Free Programmable Blocks module of MiPower, where the control responses have been observed and shown.
