RESUMEN
Con la alta penetración de renovables a nivel de distribución, debido a la interacción entre la potencia activa inyectada a la red y su impedancia, ocurren incrementos de voltaje en el PCC que pueden sobrepasar los límites seguros. En este contexto, en este trabajo se desarrolla un esquema Volt-Var, como función auxiliar para un inversor trifásico, como complemento al lazo de control de potencia. Se lleva a cabo la configuración del sistema Volt-Var de acuerdo con las condiciones de red y de las capacidades del inversor. Para propósitos de validación, se toma como caso de estudio, un inversor de 1.1 kVA sobre el cual se llevan a cabo pruebas preliminares de simulación y pruebas experimentales, donde se evalúa el desplazamiento de la onda de corriente como significado físico del intercambio de potencia reactiva, para tres escenarios de impedancia de red; con lo cual se verifica la efectividad del esquema Volt-Var.
Palabras Clave: Control Volt-Var, Inversor Fotovoltaico, Servicio Auxiliar.
ABSTRACT
With the high penetration of renewables at the distribution level, due to the interaction between the injected active power to the grid and its impedance, increments of voltage at the PCC take place, which can exceed the safe limits. In this context, this work develops a Volt-Var scheme, as auxiliary function for a three-phase inverter, as complement to the power control loop. The Volt-Var configuration is set according with the grid impedance conditions and the inverter capacity. For validation purposes, a 1.1 kVA inverter is used as study case, for which preliminary simulations tests are carried out as such as experimental tests, where the current wave displacement is evaluated as a physical meaning of reactive power exchange.
Keywords: Volt-Var Control, PV Inverter, Ancillary Services.
