Análisis de la estabilidad de ángulo de un sistema de suministro de energía eléctrica con la incorporación de las energías renovables

Abstract

Stability is an important part of the studies that are carried out on Energy Systems due to the importance of knowing if the system is capable of returning to its equilibrium conditions after a disturbance has occurred, the objective of the analysis being to observe if network synchronism is lost in this multimachine model. The more generators, lines, loads, speed controllers, and voltage regulators enter the system, the complexity of the system increases and therefore a stability study becomes complicated to carry out with simple mathematical models, using computational tools for this purpose. The increasing insertion of renewable energies such as wind farms or photovoltaic plants in transmission, subtransmission and/or distribution systems leads to questioning whether the system's response to failures is modified and what degree of affect it would have. In this article, the analysis of angle stability in an electric power supply system is disclosed, the system under analysis is modeled with each of its elements and characteristics, this system model has the particularity of being modified with the incorporation of renewable energies; it focuses on the simulation of contingencies that allows the subtransmission system to be analyzed when renewable energy sources have not been incorporated into the network bars; and then, using the same contingencies, observe the behavior of the electrical system when renewable energy sources have been incorporated in some bars of the system.
