Integration of plug in hybrid electric vehicles and electric vehicles (PHEVs and EVs) includes a wide area of topics like grid effects, different charging concepts, charger designs, harmonics from the charger etc. This short paper gives an introduction to ongoing work within this field in Sweden, and shows on research work within the topic at Chalmers University of Technology.
We discuss the evolving role of communication and control for automatic load management in electric distribution systems. We start by reprising a description of the Athens project - one of the earliest deployed examples of automatic load management at consumers enabled by communication signals. We observe that the use of communication for such systems has gone through distinct phases in its evolution...
The present paper introduces some simulation methods for flicker propagation assessment. The first method is based on current injection into the system matrix of the studied grid. Only one computation is enough to get all nodal voltages of the grid. We can thus deduce flicker propagation coefficient between any two nodes by the ratio of the relative nodal voltages. The second method requires two load-flow...
Plug-in hybrid vehicles (PHEVs) and Plug-in Electric Vehicles (PEV) are promoted in many jurisdictions worldwide as a way of reducing reliance on fossil fuels and reducing green house gases. In Canada, most utilities have initiatives in this area, with the aim to assess the impact on their electric grid of the wide scale deployment of these vehicles. There is also a significant interest on the part...
