ABSTRACT
The traditional dispatch planning methods used in Kazakhstan are extremely conservative and result in excessive consumption of resources. Moreover, the effect is multiplied by the low overall efficiency of Kazakhstan's power fleet. This chapter uses the security-constrained unit commitment (SCUC) formulation for planning and scheduling of power generator loadings in the Karaganda region of Kazakhstan. The objective of the final model is to obtain least-cost online scheduling for a definite timeline, and at the same time the schedule must comply with the network security constraints and be robust for contingencies. Since system security is the most important factor in the operation of a power system, traditional scheduling provides strong back-up against pre-contingencies by securing considerable preventive dispatch. The introduction of power sector load planning and scheduling has the potential to reduce carbon emissions and the overall expenditure required for dispatch. The proposed rolling-horizon (RH)-SCUC approaches are based entirely on the actual demand from historical data.
