Derivative-Free Power Flow Solution for Bipolar DC Networks with Multiple Constant Power Terminals
(2022)
This paper analyzes the power flow solution in bipolar direct current networks with radial structures considering multiple monopolar and bipolar constant power loads. The electrical configuration of the bipolar DC grid ...
Three-dimensional analysis of air-admission orifices in pipelines during hydraulic drainage events
(2022-11-07)
Air valves operate as protection devices in pipelines during drainage processes in order
to mitigate vacuum pressures and control the transient flows. Currently, different authors have
proposed one-dimensional models to ...
Multidimensional analysis of the evolution of the COVID-19 pandemic in countries of the Americas
(2022)
Objective. To evaluate the evolution of the COVID-19 pandemic in countries of the Americas, comparing health system data from before the appearance of the virus in the Region, accumulated cases and deaths before the ...
Power Flow in Bipolar DC Distribution Networks Considering Current Limits
(2022-09)
Power electronics converters are equipped with current controls that protect the converter from over-currents. This protection introduces non-differentiable equations into the power flow problem. The conventional Newton's ...
