Assessing the Transition of the Romanian Power System

This work presents a generic mixed integer linear programming model to determine the optimal energy and reserves scheduling of a renewable-based multi-zonal power system. In particular, through a detailed unit commitment model implementing a co-optimization of energy and reserves market with a cost minimization objective function, the developed approach determines the optimal annual energy and reserves mix of the Romanian power system in a future year (2040). The model outputs highlight the impacts in the power system in terms of operational, economic, and environmental performance. The developed optimization framework enables the provision of useful insights on the determination of the optimal transition roadmaps, by highlighting the influences and the challenges of each phase.
