The power system operator must ensure a secure electricity supply, reliable and with quality while maintaining frequency and voltage profiles stable and within the ranges required by the specific regulations for each country. Voltage control and reactive-power management are two aspects of a single activity that both supports reliability and facilitates commercial transactions across transmission networks. Distributed Generation (DG) provides benefits for the voltage control because is located close to consumption centers, as well to helping congestion relief on the transmission and distribution grids. This paper presents an analysis about the pertinence of the implementation of distributed generation systems for voltage control service in the interconnected system in Colombia. This analysis is based through grid simulations in a fraction of the sub-region of the CQR with PowerWorld. The simulation considers low operating voltage levels because of the presence of inductive loads. The results show that by connecting Distributed Generation, voltage level increases and reduce power and reactive losses.
El operador del sistema de potencia debe asegurar un suministro de electricidad seguro, confiable y con calidad mientras mantiene los perfiles de tensión y frecuencia estables y dentro de los rangos requeridos por la regulación específica de cada país. El control de tensión y el manejo de la potencia reactiva son dos elementos de una misma actividad que tiene como fin servir de soporte a la confiabilidad y facilitar las operaciones en las redes de transmisión. La Generación Distribuida (GD) proporciona beneficios para el control de tensión porque se conectada cerca de los centros de consumo y de esta manera ayuda a la congestión en las redes de transmisión y en las redes de distribución. Este artículo presenta un análisis acerca de la pertinencia de la implementación de sistemas de GD para el servicio de control de tensión en el sistema interconectado en Colombia. Este análisis se realizó usando simulaciones con el software PowerWorld en una región del sistema de potencia, específicamente en la región de Caldas, Quindío y Risaralda (CQR). Los resultados de las simulaciones muestran que al conectar GD, los niveles de tensión se incrementan y las pérdidas de potencia activa y reactiva se reducen.
