# Optimization of Electric Power Systems

 Code 11461 Year 1 Semester S1 ECTS Credits 10 Workload OT(15H) Scientific area Electrotechnics and Electronics Entry requirements Nonexistent. Mode of delivery Tutorial classes Work placements N/A Learning outcomes The overall objective of the curricular unit can be described as the understanding and study of the electricity sector organization, particularly in Portugal, and its operation from an economic perspective – to acquire knowledge on short-term operational planning. For this propose the objectives we want to reach are: • giving students an understanding of the main characteristics of a hydrothermal power system; • addressing the mathematical optimization methods, with adequate depth, and applying them to simple problems, but also demonstrating, when possible, its practical resolution in the utilities; • introducing the most current topics that emerged with the electricity sector restructuring, based on recent papers. Syllabus M1 Introduction Structure of a generic electric power system. Power system models. Power system control. Review of optimization techniques applicable to power systems. Load models. Examples. M2 Unit Commitment Formulation of unit commitment problem. Optimization methods Examples. M3 Dynamic Programming (DP) Characteristics of DP. Concept of suboptimization and the principle of optimality. Formulation of DP “backward” and “forward” recursion. Computational procedure in DP. Systems with more than one constraint. Examples. M4 Lagrangian Relaxation (LR) Concepts. Problem formulation. Primal problem-illustration. Lagrange function. Subgradient method for setting the dual variables. Dual problem-illustration. Duality gap.
