A predictive model for the missing people problem
(2021-03-01)
The disappearance of people is a multidimensional phenomenon, in which several aspects must be considered. It affects people’s security perception and consumes police resources in its treatment. Therefore, does exists an ...
An IDA-PBC Design with Integral Action for Output Voltage Regulation in an Interleaved Boost Converter for DC Microgrid Applications
(2021-12-29)
This paper describes the output voltage regulation control for an interleaved connected
to a direct current (DC) microgrid considering bidirectional current flows. The proposed controller
is based on an interconnection ...
Stabilization of MT-HVDC grids via passivity-based control and convex optimization
(2021-04-30)
This paper presents a model for stabilizing multi-terminal high voltage direct-current (MT-HVDC) networks with constant power terminals (CPTs) interfaced with power electronic converters. A hierarchical structure of ...
Optimal Design of Transmission Shafts Using a Vortex Search Algorithm

(2021-11-01)
This article shows the results of the performance study of a combined cycle plant made up of a Siemens STG-800 gas turbine and a MACCHI heat recovery boiler (HRSG) designed to produce 47.5 MW of electricity and 81908 kg / ...
High impedance fault modeling and location for transmission line
(2021-04-07)
A fault in a power system generates economic losses, security problems, social problems and can even take
human lives. Therefore, it is necessary to have an efficient fault location strategy to reduce the exposure
time ...
Analysis of sub-atmospheric pressures during emptying of an Irregular pipeline without an air valve using a 2D CFD model
(2021-09-15)
Studying sub-atmospheric pressure patterns in emptying pipeline systems is crucial because these processes could cause collapses depending on the installation conditions (the underground pipe covering height, type, fill, ...
