The control strategy proposed in this brief use the Clark's transformation known as αβ reference frame, avoiding to use phase-locked loop systems, which allows improving the dynamical performance in the energy storage devices. Passivity-based control guarantees stable operating conditions in the sense of Lyapunov for each EESS for different grid operation scenarios in the TP-MG. The design of the controllers is made by using passivity-based control (PBC) theory in conjunction to the dynamics of the error approach. A comparison to classical proportional-integral control method is used to show the applicability of the PBC approach presented in this brief. Simulation results are conducted via MATLAB/Simulink software. © 2004-2012 IEEE.Recurso electrónicoapplication/pdfenghttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/article10.1109/TCSII.2019.2893842Active and reactive power controlBilinear structureEelectrical energy storage systemsHamiltonian formulationLaypunov's stabilityPassivity-based control theoryControl theoryControllersElectric power system controlEnergy storageHamiltoniansMATLABReactive powerTwo term control systemsActive and reactive power controlsDynamical performanceElectrical energy storage systemsHamiltonian formulationsMatlab/Simulink softwarePassivity based controlPassivity-based controllersProportional-integral controlPower controlinfo:eu-repo/semantics/restrictedAccessAtribución-NoComercial 4.0 InternacionalUniversidad Tecnológica de BolívarRepositorio UTB569195641005719149364836449223500
