Regulación de la frecuencia mediante la sincronización de un sistema de generación renovable híbrido para mejorar la estabilidad

Abstract

The inclusion of non-linear loads in an Electrical Power System generates problems of various types in its operation and stability. Variables such as frequency and voltage are critically affected at certain points in the system. These voltage and frequency losses also lead to losses of power delivered to potential consumers, evidencing a poor functioning of the system in general. In this context, the following study foresees to carry out tests of a solution that allows to maintain nominal operating values in the system. The inclusion of a Virtual Synchronous generator, with the purpose of suppressing very high values or with many losses in the system and thus achieve a correct and efficient operation. To visualize this solution, the virtual synchronous generator was implemented in the IEEE 34-bar system subjected to four non-linear loads of the same reactive power, on different bars of the SEP. Finally, with the measurement of voltage and frequency in each bus in different case studies, satisfactory data are obtained in the measurements in each bus, keeping the frequency close to the nominal value and the voltage close to one per unit, optimizing the system. stabilizing it and eliminating losses in general.
