On-Line Parameter Identification of Input Output Curves for Thermal Units

This paper presents a state-of-the-art methodology of On-line Input Output Curve Identification based on the Sequential Regression Technique implemented at the Energy Control Center of the Southern California Edison Company. The proposed method, which requires little computer storage and no matrix inversion, is highly suitable for On-line application. The advantage of this approach is the capability to keep tracking the state of the thermal unit by making the coefficients of the Input Output Curve continuously adaptive to the real characteristic of the unit.
