Comparative analysis of residential load forecasting with different levels of aggregation
Peñaloza, Ana Karen Apolo; Leborgne, Roberto Chouhy; Balbinot, Alexandre (2022) [Journal article]Microgrids need a robust residential load forecasting. As a consequence, this highlights the problem of predicting electricity consumption in small amounts of households. The individual demand curve is volatile, and more ... -
A framework for reliability assessment in expansion planning of power distribution systems
Aschidamini, Gustavo Lima; Cruz, Gederson Alvaro da; Resener, Mariana; Leborgne, Roberto Chouhy; Pereira, Luís Alberto (2022) [Journal article]This article proposes a framework that uses analytical assessment of reliability to guide the expansion planning of power distribution systems (PDS) considering reliability criteria. The framework allows the estimation of ... -
Investigation of main and secondary transformers on mitigation of voltage sags, swells and interruptions in unbalanced medium voltage distribution systems
Costa, Lucas Araujo da; Gazzana, Daniel da Silva; Leborgne, Roberto Chouhy (2020) [Journal article]Since voltage interruptions, sags and swells are Power Quality (PQ) disturbances with great economic impact, studies that seek alternatives to mitigate its effects have been conducted extensively. The PQ Brazilian standard ... -
Modified methods for voltage-sag source detection using transient periods
Mohammadi, Younes; Leborgne, Roberto Chouhy; Polajžer, Boštjan (2022) [Journal article]Real-time detection of the voltage sag sources' relative location requires fast and accurate methods. Therefore, in this paper, the transient period of voltage sags is used with useful detection information, which is not ... -
Most influential feature form for supervised learning in voltage sag source localization
Mohammadi, Younes; Polajžer, Boštjan; Leborgne, Roberto Chouhy; Khodadad, Davood (2024) [Journal article]The paper investigates the application of machine learning (ML) for voltage sag source localization (VSSL) in electrical power systems. To overcome feature-selection challenges for traditional ML methods and provide more ... -
Quantifying power system frequency quality and extracting typical patterns within short time scales below one hour
Mohammadi, Younes; Polajžer, Boštjan; Leborgne, Roberto Chouhy; Khodadad, Davood (2024) [Journal article]This paper addresses the lack of consideration of short time scales, below one hour, such as sub-15-min and sub-1-hr, in grid codes for frequency quality analysis. These time scales are becoming increasingly important due ... -
A voltage-based approach for series high impedance fault detection and location in distribution systems using smart meters
Vieira, Francinei Lucas; Santos, Pedro H. M. dos; Carvalho Filho, José Maria de; Leborgne, Roberto Chouhy; Leite, Marino Piazza (2019) [Journal article]High impedance faults (HIFs) have been a major concern for protecting distribution systems and public safety hazards when involving downed conductors. The deployment of smarter grids brings new technologies for smart ...
