Objectives and competences

This course aims to analyze a practical example from the field of electrical engineering and, based on the analysis, to use an optimization algorithm to find optimal solutions to the problem.

Content (Syllabus outline)

• Overview of optimization methods suitable for power system optimizations.  • Optimization methods, suitable for optimizing the power system's nonlinear and constrained optimization problems: linear programming, nonlinear programming, dynamic programming, decomposition methods, and evolutionary strategies.  • Guidelines for optimizations in the power system with evolutionary strategies: what model structure is suitable for optimizations, how to introduce constraints, how to define the criterion function, how to introduce penalty functions, how to evaluate the criterion function, when and how to use one or more criterion functions.  • Introduction: structure of the generalized power system, elements of the power system, control of the power system, optimization of the power system in the time domain.  • Electric power system models: the concept of working, reactive and apparent power, three-phase system and three-phase power transmission, model of synchronous machine, models of transmission lines and transmission network, models of loads.  • Examples of optimizations in the power system: optimization of energy flows, optimization of operating diagrams of various production units, minimization of losses in transmission lines in the case of balanced operation, minimization of transmission losses in distribution lines in the case of asymmetries and the presence of higher harmonic components.
