Controlling DC microgrids in communities, buildings and data centers

IET Smart Grid, 2020
Microgrid technology is poised to transform the electricity industry. In the context of commercial/domestic buildings and data centers, where most loads are native direct current, DC microgrids are in fact a natural choice.

Manifestation of vortex depinning transition in nonlinear current-voltage characteristics of polycrystalline superconductor Y_{1-x}Pr_{x}Ba_2Cu_3O_7 [PDF]

, 2008
We present our recent results on the temperature dependence of current-voltage characteristics for polycrystalline Y_{1-x}Pr_{x}Ba_2Cu_3O_7 superconductors with x = 0.0, 0.1 and 0.3. The experimental results are found to be reasonably well fitted for all

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

Electric 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 ...

Observation of surface charge screening and Fermi level pinning on a synthetic, boron-doped diamond [PDF]

, 1993
Spectroscopic current-voltage (I-V) curves taken with a scanning tunneling microscope on a synthetic, boron-doped diamond single crystal indicate that the diamond, boiled in acid and baked to 500 °C in vacuum, does not exhibit ideal Schottky ...

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

e-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.
