DC voltage deviation‐dependent voltage droop control method for VSC‐MTDC systems under large disturbances

open access: yesIET Renewable Power Generation, 2020
Along with the increasing demand of large power transfer and integration of renewable energy sources, voltage source converter based multi‐terminal high‐voltage DC (VSC‐MTDC) technology has represented both challenges and opportunities. However, the DC voltage of the droop‐controlled VSC station may exceed the DC voltage limits when facing large ...

Investigation of Phase-wise Voltage Regulator Control Logics for Compensating Voltage Deviations in an Experimental Low-voltage Network [PDF]

open access: yesElectric Power Components and Systems, 2016
AbstractThis article investigates the control logics of an on-load tap-changer transformer by means of experimental system validation. The experimental low-voltage unbalanced system consists of a decoupled single-phase on-load tap-changer transformer, a 75-m 16-mm2 cable, a controllable single-phase resistive load, and an electric vehicle that has the ...

Cascaded dual fuzzy logic controller for stable microgrid operation mitigating effects of natural uncertainty in solar and wind energy sources

open access: yese-Prime: Advances in Electrical Engineering, Electronics and Energy, 2023
In a microgrid system, the perturbations due to variable solar irradiance, fluctuating wind speed, and even the sudden fluctuation in load lead to the deviation in system voltage, frequency, DC-Link voltage, etc., causing instability.
