Safety Approach of Detecting Abnormal Events (Spinning and Sliding) in Vehicular Systems
(2021)
The primary theme in the vehicles industry is the increase in automating and integrating more robust intelligent electronic systems to enhance the safe functioning, flexibility, and to extend the virtual productive age of the vehicular systems. Further, significant efforts focus on developing monitoring systems for the abnormal driving conditions such as wheel spinning and sliding that can increase the hazardous in the operating environment and speed up the wearing off process. Thus, these events play a primary role ...

Long-term voltage stability of electric power systems hosting inverter-interfaced energy sources
(2021)
The study of power system dynamics refers to the motion of electro-mechanical and electro-magnetic quantities such as voltages, currents, rotational speeds, angles and powers under the action of forces caused by system disturbances. For decades, such dynamics have been extensively dominated by large Synchronous Generators (SGs). Not a surprising statement, considering that the power systems that we know today were built based on the SG concept since the closing decades of the 19th century. It all began in 1891, when ...

Fast parallel quasi-static time series simulator for active distribution grid operation with pandapower
(IET, 2021)
The increasing penetration from intermittent renewable distributed energy resources in distribution grid brings along challenges in grid operation and planning. To evaluate the impact on the grid voltage profile, grid losses, and discrete actions from assets (e.g. transformer tap changes), quasi-static simulation is an appropriate method. Quasi-static time series and Monte-Carlo simulation requires a tremendous number of power flow calculations (PFCs), which can be significantly accelerated with a parallel High-Performance ...
