Abstract
This paper addresses the unit commitment in multi-period combined heat and power (CHP) production planning, considering the possibility to trade power on the spot market. We present a modified unit decommitment algorithm (MUD) that starts with a good feasible initial solution generated by a heuristic procedure. The heuristic procedure utilizes both the Lagrangian relaxation principle to relax the system-wide (heat and power) demand constraints and a linear relaxation of the ON/OFF states of the plants. Numerical results with realistic power plants show that on the average MUD is somewhat more accurate (0.3-0.5%) than a generic unit decommitment algorithm and significantly more efficient (1.1-3 times faster) for different planning horizons.
