Abstract
The fight against climate change and the supply of growing energy demands have lead to the evolution of electrical systems, including more renewable energy generation. Consequently, conventional energy is gradually displaced, changing the behavior of the system in the face of eventual disturbances. Despite the imminent changes, few studies have been focused on identifying the problems caused by the coexistence of both types of generation in different amounts. In this work, through the implementation of a fundamental machine-inverter system, with a high-fidelity modeling that includes the main components and controls of both types of generators, the response in the Time Domain of the Mixed Generation System to a severe disturbance is analyzed, systematically testing combinations of physical and control parameter adjustments to discover the dominant properties and mechanisms that allow to see how much the stable level of renewable energy penetration into the system can be maximized.

La lucha contra el cambio climático y el abastecimiento de las crecientes demandas energéticas han propiciado la evolución de los sistemas eléctricos, incluyendo una mayor generación de energías renovables. En consecuencia, la energía convencional se va desplazando paulatinamente, modificando el comportamiento del sistema ante eventuales perturbaciones. A pesar de los cambios inminentes, pocos estudios se han centrado en identificar los problemas que provoca la coexistencia de ambos tipos de generación en diferentes cantidades. En este trabajo, mediante la implementación de un sistema fundamental máquina-inversor, con un modelado de alta fidelidad que incluye los principales componentes y controles de ambos tipos de generadores, se determina la respuesta en el Dominio del Tiempo del Sistema Mixto de Generación ante una perturbación severa, analizando sistemáticamente combinaciones de ajustes de parámetros físicos y de control para descubrir las propiedades dominantes y los mecanismos que permiten ver cuánto se puede maximizar el nivel estable de penetración de energía renovable en el sistema.
