Abstract
Due to the great demand for energy, electrical power systems, when subjected to voltage stress, present voltage instability, generating blackouts in the system with economic losses and in the components. Through a static approach, the P-V and Q-V curves are widely used in operation studies, planning that allow us to detect the weakest bus in the system to obtain the exact location in which to connect the SVC to compensate with reactive power in order to have system voltage stability. Through this article, we evaluate a voltage stability study on the IEEE-9 bus with the Dig-Silent Power Factory 2020 program in order to compensate the system with reactive power.
