Modern Power Systems have evolved into a very complex network of multiple sources, lines, breakers, loads and others. The performance of these interdependent components decide the reliability of the power systems. A tool called “Reasoner” is being developed to deduce fault propagations using a Temporal Causal Diagram (TCD) approach. It translates the physical system as a Cause-effect model. This work...
Several topologies have been proposed for combining batteries and ultracapacitors (UC) to build a hybrid energy storage system (HESS). It is essential to quantify the performance benefits of these different circuit topologies. This will establish a metric for evaluating the performance of new topologies as well as providing the basis to select a certain topology and design a HESS optimized for the...
This paper proposes powering electric vehicles while in motion using inductive power transfer as means to address the inherent compromise that on-board electrical energy storage imposes on electric vehicle range and usage availability. Electric vehicles have been in the forefront of efforts to create transportation strategies that promise both energy-efficiency and long-term sustainability, but they...
Switched reluctance motors (SRMs) are highly non-linear. Therefore, their control over a wide speed range has unique difficulties. In addition, conventional and classic linear control techniques have limitations. In this paper, a novel digital current control for SRM drives is presented. By treating the system digitally, the controller switches between two pre-defined states to get the desired speed...
Energy storage systems (ESSs) are enabling technologies for well-established and new applications such as power peak shaving, electric vehicles, integration of renewable energies, etc. This paper presents a review of ESSs for transport and grid applications, covering several aspects as the storage technology, the main applications, and the power converters used to operate some of the energy storage...
