Abstract
Two polynomial curve fitting methods, Gram-Schmidt orthonormalization and the least-squares method, are evaluated for power system load dispatching economics analysis applications. It is shown that the Gram-Schmidt method, which does not require matrix inversion, gives more accurate fuel cost curves. Also, a constraint equation can be included in both methods to insure that incremental cost curves are monotonically increasing. Numerical examples are included to demonstrate the results
