A safety & security constrained hydrothermal scheduling model system

This paper presents a safety and security constrained hydrothermal scheduling model system. Safety is defined as the measure to take for reducing the potential damage of huge upstream dams while security is defined as the consideration of transmission capacity. The modeling system consists of three submodels: a long-term maintenance model, a long-term stochastic scheduling model and a short-term scheduling model. The paper will concentrate on the maintenance model and an application to a large hydrothermal system.
