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 ...
Optimal Location of DGs in DC Power Grids Using a MINLP Model Implemented in GAMS
(Institute of Electrical and Electronics Engineers Inc., 2018)
This paper addresses the problem of optimal location and sizing of distributed generators (DGs) in direct-current (dc) power grids by using a mixed-integer nonlinear programming (MINLP) formulation. The reduction of the ...
Output Voltage Regulation for DC-DC Buck Converters: A Passivity-Based PI Design
(Institute of Electrical and Electronics Engineers Inc., 2019)
