Distributed energy resources integration in AC Grids: A family of passivity-based controllers
(Universitat Politecnica de Valencia, 2019)
This paper presents the design and application of passivity-based control theory for distributed energy resources (DERs) integration through voltage source converters (VSC) in ac single-phase grids. The Hamiltonian ...
Optimal Power Flow on DC Microgrids: A Quadratic Convex Approximation
(Institute of Electrical and Electronics Engineers Inc., 2019)
This express brief shows a convex quadratic approximation for the optimal power flow (OPF) in direct-current microgrids (dc-μ Grid) via Taylor's series expansion. This approach can be used for solving OPF problems on radial ...
PBC approach applied on a DC-DC step-down converter for providing service to CPLs
(Institute of Electrical and Electronics Engineers Inc., 2019)
This paper addresses the problem of output voltage regulation for step-down converters (buck converters) for constant power load (CPL) applications. The model of the CPL corresponds to a hyperbolic constraint that introduces ...
