The control models presented were simulated using Simulink® and from the results we can observe that the BESS helps to reduce the error in frequency of the power system; This improvement is determined by observing that the use of a BESS reduces the standard deviation and the integral square error of the variation in frequency of the control areas in the power system.7 p.application/pdfen-UScc-by-nc-nd © Universidad Centroamericana José Simeón Cañas, Facultad de Ingeniería y Arquitectura, 2019text::journal::journal articleinfo:eu-repo/semantics/openAccessGeneración de energía fotovoltáicaRecursos energéticos renovablesPhotovoltaic power generationRenewable energy sources
