Modelling and analysis of three-phase grid-tied photovoltaic systemsJournal of Electrical Systems and Information Technology - Tập 10 - Trang 1-17 - 2023
Abraham Dandoussou, Pierre Kenfack
The global warming of the planet is as a result of human activities. Fossil fuel
depletion and its high prices have caused a worldwide economic instability;
governments around the world turn to alternative energy sources that are
pollution-free. Solar photovoltaic system is one of the biggest renewable energy
resources to generate electrical power and the fastest growing power generation

Improved-RSSI-based indoor localization by using pseudo-linear solution with machine learning algorithmsJournal of Electrical Systems and Information Technology - Tập 11 - Trang 1-20 - 2024
M. W. P. Maduranga, Valmik Tilwari, Ruvan Abeysekera
With the rapid advancement of the Internet of Things and the popularization of
mobile Internet-based applications, the location-based service (LBS) has
attracted much attention from commercial developers and researchers. Received
signal strength indicator (RSSI)-based indoor localization technology has
irreplaceable advantages for many LBS applications. However, due to multipath
fading, noise, and... hiện toàn bộ
Design of a maximum power point tracking-based PID controller for DC converter of stand-alone PV systemJournal of Electrical Systems and Information Technology - Tập 9 - Trang 1-15 - 2022
Fatema A. Mohammed, Mohiy E. Bahgat, Saied S. Elmasry, Soliman M. Sharaf
Stand-alone photovoltaic system (PV) produces a variance in the output voltage
under variable irradiation and temperature, and variable load conditions,
resulting in control challenges. The research scope is to maintain a constant
output load voltage despite variations in input voltage or load. The use of a DC
converter ensures that the output voltage of such systems remains constant
regardless of... hiện toàn bộ
An improved backward/forward sweep power flow method based on network tree depth for radial distribution systemsJournal of Electrical Systems and Information Technology - - 2021

AbstractThis paper presents an improved load flow technique for a modern
distribution system. The proposed load flow technique is derived from the
concept of the conventional backward/forward sweep technique. The proposed
technique uses linear equations based on Kirchhoff’s laws without involving
matrix multiplication. The method can accommodate changes in network structure
reconfiguration by invo... hiện toàn bộ
A novel computational technique using coefficient diagram method for load frequency control in an interconnected power systemJournal of Electrical Systems and Information Technology -
Jalal Heidary, Hassan Rastegar
AbstractThis paper proposes a novel load frequency control (LFC) approach
formulated on an optimal structure of the coefficient diagram method (CDM) in a
two-area thermal power system. As part of a realistic analysis, nonlinearities
related to governor dead band (GDB) and generation rate constraint (GRC) have
been considered. In this article, a hybrid CDM method is combined with the
optimization o... hiện toàn bộ
