Diseño de un compensador estático síncrono para la mitigación de variaciones transitorias de voltaje ante la presencia de generación fotovoltaica

Abstract

The connection of photovoltaic generation in the electricity network has shown an increase because of factors such as its low implementation cost, its availability and its non-polluting effect, but due to the fact that environmental factors are not constant, it may display a deficiency in energy quality. This research aims at designing a synchronous static controller in order to improve the voltage profiles of a photovoltaic power plant, caused by the increase or decrease in solar irradiance producing very fast voltage changes and inserting transients in the wave that is supplied to the electricity grid. The study is developed with the Matlab-simulink, Digsilent programs, and the IEEE standardized 13-bar system. The paper is organized as follows, section two provides information on distributed generation systems, system stability and compensation technologies, section three describes the compensator design, section four presents the control strategy used in the compensator, section five shows the results obtained and section six defines the conclusions.
