Power quality detection and classification using wavelet and support vector machine
(2019-09-24)
This work presents the identification and classification of various disturbances that affect the quality of energy, seen as the quality of the voltage wave (harmonics, sag, swell and flicker). For this, the wavelet transform ...
Direct Power Control Design for Charging Electric Vehicles: A Passivity-Based Control Approach
(2020-11-25)
This paper explores the controller's design for charging batteries for electric vehicle applications using the direct power representation of the system. These controllers' design is made via passivity-based control (PBC) ...
A mixed-integer convex approximation for optimal load redistribution in bipolar DC networks with multiple constant power terminals
(2022)
This paper proposes a mixed-integer convex model for optimal load-balancing in bipolar DC networks while considering multiple constant power terminals. The proposed convex model combines the Branch and Cut method with ...
Stationary-state analysis of low-voltage DC grids
(2021-01-01)
The optimal power flow is a classic method for alternating current networks, which can also be applied to direct current networks. However, it is needed to design new methods that guarantee convergence and global optimum. ...
Adaptive control for second-order DC-DC converters: PBC approach
(2021)
This chapter deals with the design of a passivity-based controller for DC-DC converters by using a general representation for second-order converters, that is, buck, boost, buck-boost, and noninverting buck-boost converters. ...
Adaptive Sensorless PI+Passivity-Based Control of a Boost Converter Supplying an Unknown CPL
(2022)
This paper presents an adaptive control to stabilize the output voltage of a DC–DC boost converter that feeds an unknown constant power load (CPL). The proposed controller employs passivity-based control (PBC), which assigns ...
High impedance fault modeling and location for transmission line✰
(2021)
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 and ...

Control of Photovoltaic Plants Interconnected via VSC to Improve Power Oscillations in a Power System
(2022)
This paper presents an integrated methodology applied to photovoltaic (PV) plants for improving the dynamic performance of electric power systems. The proposed methodology is based on primary frequency control, which adds ...
On the Optimal Reconfiguration of Radial AC Distribution Networks Using an MINLP Formulation: A GAMS-Based Approach
(2022)
This paper addresses the problem of the optimal reconfiguration of medium-voltage distribution networks by proposing a mixedinteger nonlinear programming (MINLP) model. The objective function of this optimization model is ...
