Price based unit commitment for bidding strategies in Turkish market under unit and system constraints

This study investigates price based unit commitment (PBUC) problem which is used to optimize generation schedules of companies in electricity markets. Solution algorithm proposed is based on Dynamic Programming (DP) and Lagrange Relaxation (LR) methods and solves the optimization problem for a generation company having many generating units with different cost characteristics. Unit constraints including; ramprate limits, minimum ON/OFF times, generation capacities of individual units, and spinning reserve requirements are taken into account in the problem formulation. Performance of the proposed algorithm is assessed through numerical analysis.
