Flujo óptimo de potencia : herramienta computacional para el cálculo de flujos óptimos de potencia en corriente alterna, considerando diferentes formulaciones matemáticas para las restricciones del problema.

Abstract

In the present document corresponding to the Curricular Integration Work (TIC) a computational tool is developed using the Python programming language that allows solving the problem of the Optimal Power Flow in alternating current (OPF-AC), and it is presented a collection of information related to the problem: mathematical formulations and solution methods. The implementation of several mathematical models of OPF-AC will be carried out using the PYOMO Python library. Alternatives for modeling the restrictions of the nodal balance, limits of power flows will be considered. In addition, the OPF-AC model will be implemented considering the quadratic relaxation of the power flow restrictions. A section is presented for the proper management of the program where the user can easily select the different models of objective function, case studies. This tool is applied to the IEEE 14-Bus system and to the Ecuadorian National Interconnected System (SNI) considering two hydrological scenarios: rainy and dry, for which the results of the total generation cost, generation power and demand of the system, which are presented through graphs and tables with their respective analysis.
