Optimizing the schedule of thermal generators is probably the most important task when the
operation of power systems is managed. This issue is known as the unit commitment …

Abstract The Unit Commitment problem in energy management aims at finding the optimal
production schedule of a set of generation units, while meeting various system-wide …

The short-term unit commitment (UC) problem in hydrothermal power generation is a large-
scale, mixed-integer nonlinear program, which is difficult to solve efficiently, especially for …

Abstract The Unit Commitment problem in energy management aims at finding the optimal
productions schedule of a set of generation units while meeting various system-wide …

A demand response (DR) problem is considered entailing a set of devices/subscribers,
whose operating conditions are modeled using mixed-integer constraints. Device …

With the fast-growing demand in the electricity market of the last decades, attention has
been focused on alternative and flexible sources of energy such as hydro valleys. Managing …

This paper provides the convex hull description for the basic operation of slow-and quick-
start units in power-based unit commitment (UC) problems. The basic operating constraints …

We give strong formulations of ram** constraints—used to model the maximum change in
production level for a generator or machine from one time period to the next—and …

This paper provides the convex hull description of the single thermal Unit Commitment (UC)
problem with the following basic operating constraints:(1) generation limits,(2) start-up and …

Planning a public transportation system is a complex process, which is usually broken down
in several phases, performed in sequence. Most often, the trips required to cover a service …
