The passivity-based control (PBC) theory is selected as a nonlinear control technique, since the open-loop dynamical model exhibits a port-Hamiltonian (pH) structure. The PBC theory exploits the pH structure of the open-loop dynamical system to design a general control law, which preserves the passive structure in closed-loop via interconnection and damping reassignment. Additionally, the PBC theory guarantees globally asymptotically stability in the sense of Lyapunov for the closed-loop dynamical system. Simulation results in a three-phase radial distribution network show the possibility to control the active and reactive power independently as well as the possibility to use the SMES system connected through a PWM-CSC as a dynamic power factor compensator for time-varying loads. All simulations are conducted in a MATLAB/ODE package. © 2004-2012 IEEE.Recurso electrónicoapplication/pdfenghttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/article10.1109/TCSII.2018.2805774Distribution networksPassivity-based control (PBC)Pulse-width modulated current-source converter (PWM-CSC)Superconducting energy storage system (SMES)DampingDynamical systemsElectric energy storageElectric power distributionEnergy storageIntegrated circuit interconnectsMagnetic storageMathematical modelsMATLABPulse width modulationReactive powerSuperconducting coilsSuperconducting magnetsActive and reactive power controlsEnergy storage systemsGlobally asymptotically stabilityIntegrated circuit interconnectionsPassivity based controlPwm-cscRadial distribution networksSuperconducting magnetic energy storage systemPower controlinfo:eu-repo/semantics/restrictedAccessAtribución-NoComercial 4.0 InternacionalUniversidad Tecnológica de BolívarRepositorio UTB569195641005719149364837104976300
