SCES Integration in Power Grids: A PBC Approach under abc, αβ0 and dq0 Reference Frames

2020-03-262020-03-262018Proceedings of the 2018 IEEE PES Transmission and Distribution Conference and Exhibition - Latin America, T and D-LA 20189781538658444https://hdl.handle.net/20.500.12585/8863This paper presents an integration of three-phase supercapacitor energy storage (SCES) in power grids via passivity-based control (PBC) theory under different reference frames. The SCES systems have the possibility to interchange active and reactive power between the supercapacitor and converter to the electrical power network. The active power is directly related to the energy stored on the supercapacitor, while the reactive power is redistributed by the forced commutated switches present in the voltage source converter (VSC) used to integrate the SCES system to the power grid. PBC theory allows designing Lyapunov stable controllers for autonomous and non-Autonomous dynamical sys-Tems via port-Hamiltonian (pH) representations. The averaging modeling theory employs to develop the controllers under abc, alpha\beta and dq reference frames. Simulation results show the possibility of using the SCES devices to compensate active and reactive power in power grids dynamically in all operating quadrants. All simulations are conducted via MATLAB/SIMULINK software. © 2018 IEEE.Recurso electrónicoapplication/pdfenghttp://creativecommons.org/licenses/by-nc-nd/4.0/SCES Integration in Power Grids: A PBC Approach under abc, αβ0 and dq0 Reference Framesinfo:eu-repo/semantics/conferenceObject10.1109/TDC-LA.2018.8511707Active and reactive power controlLyapunov's stability theoryPassivity-based control theory port-Hamiltonian systemsSupercapacitor energy storage systemThree-phase power grids.Control theoryControllersElectric power transmission networksEnergy storageHamiltoniansMATLABPower controlPower convertersReactive powerSupercapacitorActive and reactive power controlsLyapunov's stability theoriesPort-Hamiltonian systemsPower gridsSupercapacitor energy storagesElectric power system controlinfo:eu-repo/semantics/restrictedAccessAtribución-NoComercial 4.0 InternacionalUniversidad Tecnológica de BolívarRepositorio UTB569195641005719149364836449223500
