This article describes the circulating current phenomenon that takes place in bipolar, meshed DC distribution grids. A difference in resistance between the conductor changes the distribution of the current on the conductors. This provokes a net current to flow, which is in turn measured by the residual current protection scheme, used to detect and isolate ground faults in the system, even though there...
Meshed dc distribution grids have advantages over radial connected ones. Challenges arise when this is done on the same voltage level and the full potential power might not be usable in certain configurations. This paper shows how the power flow in meshed dc grids can be increased by limiting the currents at congested lines. This can be done in a decentralized way with only local current measurements...
The development of a Smart Charging Controller (SCC) for dynamic charging of Electrical Vehicles (EVs) is described in this paper. The controller makes it possible to charge electric cars with the fluctuating power generated by photovoltaic panels. This way, a house owner can utilize their own produced energy locally. When solar power is not enough, the controller dynamically regulates the charging...
