Direct Predictive Power Control Strategy to Improve Charging and Power Quality of Autonomous Robotic Electric Vehicle Charging Systems Vrije Universiteit Brussel
Emerging wide bandgap (WBG) semiconductors, such as silicon carbide (SiC), will enable chargers to operate at higher switching frequencies to increase efficiency and reduce power density. This paper focuses on modelling SiC technology-based off-board robotic chargers for electric vehicles (EVs) and the design of its robust model predictive control (MPC). The three-phase active front-end (AFE) converter topology is considered on modelling and ...
Power quality improvements through power electronic interfaced distributed generation Universiteit Gent
In low-voltage distribution networks a large amount of single-phase nonlinear loads are connected. This leads to the combined presence of power system unbalance and harmonic distortion. The research presented in this paper focusses on these steady-state power quality problems. It uses a harmonic load flow program, implemented in symmetrical components, to investigate the influence of several single-phase inverter control strategies used to ...
Power quality improvement in smart grids using electric vehicles: A review Vrije Universiteit Brussel
The global warming problem together with the environmental issues has already pushed the governments to
replace the conventional fossil-fuel vehicles with Electric Vehicles (EVs) having less emission. This replacement has led to
adding a huge number of EVs with the capability of connecting to the grid. It is noted that the presence of such vehicles
may introduce several challenges to the electrical grid due to their ...

The effect of a reduced power quality on the energy efficiency of stand-alone generator systems Universiteit Gent
It has already been thoroughly validated that the efficiency of direct online motors is susceptible towards certain power quality parameters such as voltage unbalance or harmonic voltage distortion. It can be assumed that electrical generators are also susceptible to these parameters, but to the author's knowledge this effect has not yet been evaluated in scientific studies. This paper starts from the well studied additional loss mechanisms ...
Review of FACTS technologies and applications for power quality in smartgrids with renewable energy systems Vrije Universiteit Brussel
In the last two decades, emerging use of renewable and distributed energy sources in electricity grid has creatednew challenges for the utility regarding the power quality, voltage stabilization and efficient energy utilization.Power electronic converters are extensively utilized to interface the emerging energy systems (without and withenergy storage) and smart buildings with the transmission and distribution systems. Flexible ac ...
Advanced Edge Computing Framework for Grid Power Quality Monitoring of Industrial Motor Drive Applications Vrije Universiteit Brussel
In large-scale industrial machine applications (IMAs) during condition monitoring, all sensor devices can produce raw data up to 15TB of data/week. Transmitting these large high-frequency data sets to the cloud to closely monitor the operational environment and make decisions is not feasible for two reasons: (a) bandwidth and latency issues and (b) higher cost of data transfer and storage. Condition monitoring applications usually extract ...
