Electric power systems (EPS) are exposed to disconnections of their elements, such as transmission lines and generation units, due to meteorological factors or electrical failures. Thus, this research proposes a smart methodology for the re-entry of elements that have been disconnected from the EPS due to unforeseen events. This methodology is based on optimal AC power flows (OPF-AC) which allow verifying the state of variables such as voltage, angular deviation, and power (these variables are monitored in normal and fault conditions). The proposed study considers contingencies N-2, N-3, N-4, and N-5, for which the disconnection of transmission lines and generation units are carried out randomly. The analysis of the EPS after the disconnections of the elements is carried out by means of the contingency index, with which the impact that the disconnections of the elements have on the EPS is verified. In this way, the optimal route is generated to restore the elements that went out of operation, verifying that when the elements re-enter the acceptable limits, voltage and voltage angle are not exceeded. According to the results of the methodology used, it was found that NM contingencies can be applied in the proposed model, in addition to considering stability restrictions, modeled as restrictions on acceptable voltage limits, and a new restriction for the voltage angle between the differences of the bars.
Bajo el contexto de una dependencia por el consumo de combustibles fósiles, causantes del calentamiento global, el mundo requiere energía limpia y sostenible. En los últimos años se han realizado grandes avances en el ámbito de la energía renovable y sostenible. Por lo que el desarrollo energético sostenible resulta ser fundamental para satisfacer la creciente demanda de energía, preservando a la vez la calidad medioambiental, así como los recursos naturales necesarios en el presente y para el futuro. Así mismo, para lograr esta sostenibilidad es necesario realizar una transición energética centrada en el uso de energías renovables. Las edificaciones energéticamente sostenibles tienen un papel crucial para minimizar el impacto ambiental, ya que, haciendo uso de la tecnología solar fotovoltaica, por ejemplo, son capaces de generar gran parte o la totalidad de la energía que el edificio demanda. Este documento tiene como objetivo el diseño de una microrred óptima que hace uso del recurso solar en el software Homer pro, para otorgar sostenibilidad energética a uno de los bloques de la Universidad Politécnica Salesiana - Campus Sur. Para ello se hace uso de datos de irradiancia solar propia del sector, así como los datos de demanda energética del determinado bloque. Los resultados conseguidos dejan en claro que la opción de incorporar paneles solares y un banco de baterías a la microrred resulta ser la alternativa menos costosa y la que, al mismo tiempo otorga un mayor grado de sostenibilidad a la edificación.
