Abstract

This paper focuses on the re-scheduling problem for utility plant operation. The optimal scheduling problem is described as LP model, and solved by the primal affine scaling algorithm. We try to re-optimize the perturbed LP model using warm-start. Numerical example shows that the warm-start solve the problem about half the time which the cold-start does.
