Abstract

This paper describes an investigation of a dynamic bias factor in the automatic generation control process of a power utility. In an isolated power system such as in Newfoundland, the proper selection of the bias factor is very important since it adjusts generation to restore system frequency to 60 Hz. A constant factor is used that is nearly equal to the system frequency-response characteristic. Utilization of a dynamic value would improve the overall system regulation by following this characteristic more closely. Using simulation techniques, a model of the Newfoundland and Labrador Hydro Power System is implemented and tested using different control schemes for determining the dynamic bias factor
