An on-line AGC compliance evaluator

Abstract

This paper presents a method to calculate the compliance of a given operating generator acting under automatic generation control (AGC). It is a measure of how far the actual output will deviate from the desired MW output. The approach also applies the Signal Processor Toolbox from Mathworks to derive a polynomial equation representing the transfer function relating the desired input to the actual output signal. The transfer function will be used to generate expected output responses for given desired input signals. These expected output responses are compared to the actual output responses for various types of transfer functions. This approach has been tested on nine different units supplied by PJM interconnection.
