Voltage and Frequency Regulation on Isolated AC Three-phase Microgrids via s-DERs
(IEEE Computer Society, 2019)
This paper addresses the voltage regulation problem on isolated three-phase microgrids via passivity-based control (PBC) with a proportional regulator under the abc reference frame. This reference frame is employed to ...
Location of FACTS Devices in Power Systems: Application to the IEEE 9 bus System
(Institute of Electrical and Electronics Engineers Inc., 2019)
This paper proposes a methodology to find the location of a flexible transmission system in AC in a power system, based on a nodal order and the analysis of repetitive power flows. To check the proposed methodology, the ...
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 ...
