Electric vehicles (EVs) can have noteworthy impact on power system dynamic performance. This paper develops two novel controllers which can take into account the random time delay in the communication channel of the control system. With the designed robust controller, the system can utilize EVs to participate in automatic generation control (AGC) processes so as to assist conventional thermal power units to respond rapidly and accurately to load fluctuations, as well as to enhance the capability of a power system to accommodate renewable energy forms such as wind power. Owing to the distributed nature of EVs, a networked control scheme for EVs' participation in frequency regulation is first proposed in the paper. A closed-loop block diagram, which incorporates EVs and wind power, is then developed. Two controllers are then designed based on rigorous linear matrix inequalities (LMI) theory to ensure the robustness and stability of the system. Finally, comprehensive case studies based on a two-area equivalent of the IEEE 39-bus test system are performed to demonstrate the effectiveness of the proposed methods.

“…This reduces the required Sample index (n) Averaged frequency measurement (Hz) governor activity of spinning reserve and increases the wind power penetration without significant increase of grid demand-supply balancing cost. However, care needs to be taken to consider the regional supply-and-demand balance to prevent an unwanted increase of Tieline flow as discussed in [26]. In principle this approach can also be used on very large roadway systems as the vehicles move.…”

Plug-in EVs are being heralded as a step towards acceptance of pure EV's. However concerns remain regarding uptake by consumers, in terms of range anxiety and economic operation. These concerns are mitigated if energy can be transferred to the vehicle while it is moving, but there are implications in terms of the highway infrastructure required without restricting a vehicle's freedom to move while providing power over air-gaps in excess of 200mm. Such flexibility brings with it problems that are not normally inherent in stationary systems where electronic alignment may be employed to control magnetic coupling.The system must cope with variances as seen by both the power supply and the EV, while ensuring that the power receiver is compatible with both stationary and roadway systems. This paper discusses recent developments in wireless charging infrastructure for EV's and describes systems that may be suitable in future. As vehicles operate on the Grid they will constitute a substantial load that must be managed. A solution is presented here at little infrastructural cost such that the Grid, 'on load' has better power quality than 'off-load'.

“…In [5][6][7][8][9][10], it has been shown that the widespread adoption of EVs could negatively impact the distribution network if charging is not properly coordinated. Grid impacts of uncoordinated charging include, but are not limited to, increased voltage imbalance [7], increased grid losses [8], overloading [6], fluctuation of grid frequencies [11], and increased harmonic distortion [12]. In turn these effects result in a decrease in the operational efficiency of the grid and in the life span of electrical devices.…”

In recent years, a wide variety of centralised and decentralised algorithms have been proposed for residential charging of electric vehicles (EVs). In this paper, we present a mathematical framework which casts the EV charging scenarios addressed by these algorithms as optimisation problems having either temporal or instantaneous optimisation objectives with respect to the different actors in the power system. Using this framework and a realistic distribution network simulation testbed, we provide a comparative evaluation of a range of different residential EV charging strategies, highlighting in each case positive and negative characteristics.
