Abstract
To achieve more economical and secure system operations short-term operational planning is very important. Although many methods focusing on unit commitment have been proposed, the resulting schedule is not always acceptable by system operators. This is because it does not consider all system operational constraints such as security in contingency cases, which are very difficult to represent and treat explicitly.
This paper proposes an optimization method for short-term operational planning, considering such general constraints for secure system operations. This proposed optimization method employs a schedule modification and a search method which takes application domain heuristics into account.
This method has proved to be practical and efficient from numerical simulations.
