A Linear Programming Method for Unit Commitment Incorporating Generator Configurations, Reserve and Plow Constraints

A method of automatic unit commitment in a predominantly thermal power system is described. Linear programming techniques are used to dispatch plant at each time interval to minimise production cost over a load peak, or a daily or weekly load cycle. Generator configurations, flow constraints, functional reserve and time-limited reserve are modelled, with the capability for individual restrictions on any unit. The method has been implemented for operator usage in a control centre.
