Dynamic Economic Dispatch of Generation

Abstract

A set of procedures and algorithms are developed for dynamic economic dispatch of generation units. When coupled with a short-term load predictor, "look- ahead" capability is provided by the dynamic economic dispatch that coordinates predicted load changes with the rate-of- response capability of generation units. Dynamic economic dispatch also enables valve-point loading of generation units. Two examples are provided which demonstrate that our approach overcomes the severe limits on the number of units that could be dynamically dispatched in past approAches.
