Benders decomposition has been broadly used for security constrained unit commitment problems, despite the fact that it may present convergence difficulties due to instabilities and to the mixed integer nature of the unit ...

Increased level of flexibility is essential in power systems with high penetration of renewable energy sources in order to maintain the balance between the demand and generation. Actually, the flexibility provided by ...

The subject of this research brings a problem linked with a theoretical model about leadership developed by Likert (1975), and with a theoretical model of organizational commitment by Allen and Meyer (1990, 1991, 1997). ...

This paper presents a new polyhedral approximation for the quadratic cost curve of thermal units for the unit commitment problem. The approximation is tight, can be represented by rational numbers, and its size grows ...

This paper presents a novel long-term model for the joint expansion planning of power and hydrogen systems with short-term operational considerations. We propose linear reserve constraints with adjustable parameters within ...

An increased use of variable generation technologies such as wind power and photovoltaic generation can have important effects on system frequency performance during normal operation as well as contingencies. The main ...
