CAMPANA, M.; MASACHE, P.; INGA, E.  e  CARRION, D.. Voltage stability and electronic compensation in electrical power systems using simulation models. Ingenius [online]. 2023, n.29, pp.9-23. ISSN 1390-860X.  https://doi.org/10.17163/ings.n29.2023.01.

Increased demand in the different electrical power systems (EPS) has a negative impact in voltage stability, reliability and quality of the power supply. Voltage profile is reduced when generation units are not capable of supplying reactive power to the EPS at the times it is required. With the development of power electronics and complex control systems, flexible alternating current transmission system (FACTS) devices have been introduced. In this article, the impact of the introduction of a type of FACTS that allows reactive power compensation in the EPS is analyzed in detail. Furthermore, a methodology to decide the capacity of the Static Synchronous Compensator (STATCOM) and its optimal location with the execution of continuous power flows (CPF) will be analyzed. Finally, the positive impact of installing a Power System Stabilizer (PSS) control to ensure voltage stability in the EPS will be studied. This article is developed using the IEEE 14- bus base system under two mathematical models for power flow calculation developed in MATLAB software, which are: i) through the power balance equations and ii) Newton Raphson with the toolbox PSAT.
