Abstract-Electrical vehicles (EVs) are presenting increasingly potential to replace the conventional fossil fuel based vehicles due to environmental friendly characteristic. Accordingly, Charging Stations (CS), as an intermediate between grid and large numbers of EVs, are supposed to have more critical influence on future smart transportation network. This paper explores an off-board charging station upgraded with flywheel energy storage system that could provide a reactive power support to the grid utility. A supervisory control scheme based on distributed bus signaling is proposed to coordinate the operation of each component in the system. As a result, the charging station could supply the reactive power support to the utility grid without compromising the charging algorithm and preserve the battery's lifetime. Finally, the real-time simulation results based on dSPACE1006 verifies the proposed strategy.

“…Finally, the wind farm has been modelled using a total of five aggregated wind turbine clusters of different rated power (S R1 = 390 MVA, S R2 = 300 MVA, S R3 = 200 MVA, S R4 = 100 MVA and S R5 = 10 MVA). The machine-side converter of each of the wind turbines is used to control the wind turbine dc-link voltage E DC [3], [23].…”

Abstract-Despite being more efficient, LCC-HVDC links for the connection of large off-shore wind farms have ac-filter bank size as one of their main drawbacks. This paper shows how the HVDC rectifier filter banks can be substantially reduced by taking advantage of the additional control possibilities offered by the use of wind turbines with fully rated converters.PSCAD simulations validate wind farm and diode rectifier HVDC link operation with a capacitor and filter bank five times smaller than its usual value. The proposed control algorithm allows for good harmonic and reactive power sharing between the different wind turbines.As the reduced capacitor bank operation leads to a redistribution of harmonic and reactive currents, an efficiency study has been carried out to evaluate the new power loss distribution with the reduced filter banks.

“…On the contrary, a low speed flywheel has been used in this paper, extending the concept commonly used for balancing of production variations of wind parks [12]- [14]. The novelty introduced here involves essentially decentralized control principle, the correct operation of which relies on detection of the voltage variations in the common DC bus.…”

Abstract-This paper deals with the design of a fast DC charging station (FCS) for hybrid electric vehicles (HEVs) that is connected at a remote location. Power rating of this new technology can go up to a hundred kW and it represents a main challenge for its broad acceptance in distribution systems. In that sense, growing number of these stations, if operated in a nonflexible regime, will start to cause problems in future distribution systems such as overloads of local network's corridors and reduction of its total equivalent spinning reserves. A power balancing strategy based on a local energy storage system (ESS) is proposed in this paper. Flywheel has been selected as the means of storing energy as it provides high power density and does not have significant performance degradation along its lifetime. Implemented control algorithm uses the energy stored in flywheel to compensate for the peak of power introduced by HEV charger, avoiding big initial stress in grid converter and also is able to limit the maximum extracted power. In addition, feed-forward compensation has been implemented to reduce the voltage dip within the station. Real time simulation results, that prove the validity of proposed approach, have been presented.
