A novel AGC simulation scheme based on reduced order prime mover models

Abstract

This paper presents a new simulation scheme for AGC studies of power system. The proposed scheme uses a different set of assumptions from that conventionally used. In this scheme, all the areas have been considered to be operating at the same frequency. Further, the proposed approach can preserve the identity of each generating unit. Additionally, the computational complexity has been reduced by resorting to lower order generating unit models. In this context, model order reduction techniques have been used to obtain lower order models for AGC studies. The effectiveness of the new simulation approach is demonstrated by considering the IEEE 30 bus test system as a 3 area system.
