Tight MIP formulations of the power-based unit commitment problem
This paper provides the convex hull description for the basic operation of slowand quick-start units in power-based unit commitment (UC) problems. The basic operating constraints that are modeled for both types of units are (1) generation limits and (2) minimum up and down times. Apart from this, the startup and shutdown processes are also modeled, using (3) startup and shutdown power trajector...
متن کاملA tight MIP formulation of the unit commitment problem with start-up and shut-down constraints
This paper provides the convex hull description for the following basic operating constraints of a single power generation unit in Unit Commitment (UC) problems: 1) generation limits, 2) startup and shutdown capabilities, and 3) minimum up and down times. Although the model does not consider some crucial constraints, such as ramping, the proposed constraints can be used as the core of any UC fo...

Tight MIP formulations for bounded up/down times and interval-dependent start-ups
Switching machines on and off is an important aspect of unit commitment problems and production planning problems, among others. Here we study tight mixed integer programming formulations for two aspects of such problems: bounded length onand off-intervals, and interval-dependent start-ups. For the problem with both these aspects we develop a tight (convex hull) formulation involving additional...
متن کاملStart up Cost constraint Optimization using Lagrangian Algorithm for Unit Schedule in Electrical Power System
Electricity companies typically possess numerous units and they need to commit units because electricity cannot be stored in a large-scale system and demand is a random variable process fluctuating with the time of the day and the day of the week. A problem that must be frequently resolved by a electricity utility is to economically determine a schedule of what units will be used to meet the fo...
