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.
