Con el creciente uso de energía eólica surge la necesidad de modificar los sistemas eléctricos de potencia, debido a la falta de inercia que caracteriza la generación renovable. Se plantea emular la respuesta inercial de aerogeneradores para mitigar estos efectos ocasionados por una configuración que le impide reaccionar ante fallas ocurridas en la red eléctrica. Para validación de lo propuesto se estudia la aplicación de inercia virtual en los parques eólicos Los Cocos, Larimar 1 y Larimar 2, que representan el mayor porcentaje de generación eólica de la República Dominicana. Para analizar el efecto de la configuración propuesta en la estabilidad del Sistema Eléctrico Nacional Interconectado se utilizó el software Power Factory DIgSILENT, donde se hacen simulaciones bajo distintos parámetros de carga para obtener las curvas de variación de la frecuencia eléctrica frente a distintos valores de la constante de inercia al ocurrir una falla por desconexión de una central generadora. Con el fin de aplicar la inercia virtual en los aerogeneradores se utiliza la electrónica de potencia para realizar la inyección de potencia activa a la red eléctrica cuando ocurre una falla en el sistema eléctrico. Se desarrolla un modelo dinámico con base en el control ROCOF (Rate of Change of Frequency) cuyo objetivo es inyectar potencia activa al sistema dependiendo de la variación de frecuencia. Realizando las simulaciones se comprueba que aplicando inercia virtual se obtiene una mayor estabilidad en el sistema eléctrico y menos probabilidad de un posible colapso del sistema eléctrico.
With the increasing use of wind energy, the need arises to modify electrical power systems, due to the lack of inertia that characterizes renewable generation. It is proposed to emulate the inertial response of wind turbines to mitigate these effects caused by a configuration that prevents it from reacting to failures in the electrical network. To validate what is proposed, the application of virtual inertia is studied in the Los Cocos, Larimar 1, and Larimar 2 wind farms, which represent the highest percentage of wind generation in the Dominican Republic. To analyze the effect of the proposed configuration on the stability of the Interconnected National Electric System, the Power Factory DIgSILENT software was used, where simulations are carried out under different load parameters to obtain the curves of variation of the electrical frequency against different values of the constant inertia when a fault occurs due to disconnection of a generating plant. To apply virtual inertia to wind turbines, power electronics are used to inject active power into the electrical grid when a fault occurs in the electrical system. A dynamic model is developed based on the ROCOF (Rate of Change of Frequency) control whose objective is to inject active power into the system depending on the frequency variation. Performing simulations, it is found that applying virtual inertia greater stability is obtained in the electrical system and less chance of a possible collapse of the electricity system.
