Minimum loss power flow in hydro thermal electric power systems based on Kron's loss formula

ABSTRACT We discuss the formulation of the optimal minimum loss hydro-thermal power flow problem in electric power systems on the basis of Kron's loss formula as the objective function. We present results of computational experience with a Newton's iterative implementation using two standard test systems. Our conclusion is that it is extremely important to have an accurate loss model representation due to the potential errors as well as slow and difficult convergence behavior of the process.
