In order to push Electric Vehicles (EVs) into the mainstream, the wide deployment of charging stations that can serve multiple classes of customers (e.g. fast charge, slow charge etc.) and provide a certain level of Quality of Service (QoS) is required. However, the operation of the power grid becoming more strenuous due to the addition of new large loads represented by EVs. Hence in this paper we propose a control and resource provisioning framework that can alleviate the strain on the power grid. We propose two design problems; first one considers a charging station located in a big metropolitan with a large and highly stochastic EV demand. For this case, we propose a pricing based control mechanism to maximize the total aggregated utility by controlling the arrival rates. Second case provides a capacity planning framework for stations located in small cities where arrival rates can be obtained via profiling studies. At each model, station draws a constant power from the grid and provides QoS guarantees, namely blocking probability, to each class. Hence total stochastic demand is replaced with a deterministic one, by sacrificing to reject a very few percentage of customers. Our results indicate that significant gains can be obtained with the proposed model.

In this paper, a method of electric vehicles charging with the use of large truck/bus vehicles moving along national highways and provincial roads is proposed and described. The method relies on charging vehicles from trucks while moving either with plug in electric connection or by electromagnetic induction via loosely coupled coils. Open research challenges and several avenues or opportunities for future research on Electric Vehicles Charging are outlined. The proposed method overcomes the disadvantages of the so far known techniques. The advantages of this method compared to the so far proposed methods are a) economical, easy and safe procedure, b) increase of the energy transfer efficiency factor, c) minimization of the delay in vehicle movement during the charging procedure and d) reduction of the environmental contamination with CO2 or electromagnetic radiation.

The integration of distributed generation technologies into distribution networks creates a number of technical issues. In order to analyze a grid and examine the impacts of distributed power penetration, considerations such as the dynamic behavior of powers systems that entails transient stability analysis, grid capacity and limits characterization need to be taken into account. Besides, this kind of study is very important to ensure the network's secure operation under fault incidents. Although, in the current paper, Steady State and Dynamic Analysis configurations are proposed in order to determine the allocation, maximum capacity of embedded generation that may be inhabited within a real island power system, emphasis is paid on the Dynamic Analysis configurations. In this way, it is possible to check the off-grid system's behaviour under normal operation and against several disturbances onto the grid. Geothermal plants using basic machine model such as synchronous generator, exciter and governor and Wind farms employing Doubly-fed Induction Generator (DFIG) technology were chosen throughout this research work. The adequate stability margin of the system was investigated upon the fault ride through capability and frequency response of the network elements whereas among the most critical perturbations was a three phase fault application at the connection point of the wind farm. Moreover, two different exciter models (IEET1 & EXST1) were chosen to perform open-circuit setpoint step tests and record their field voltage and terminal voltage responses after tuning application. PSS®E software simulation tool of Siemens PTI will be utilized throughout this work.

The importance of electric and hybrid vehicles as a serious alternative to conventional-driven vehicles especially in urban areas increases. But the low capacity of the battery minimizes the use for the long distance. A quick charging time realized by a high power level of 50 kW (compared with a standard charging station) enables a higher scope per day. Therefore the development of an infrastructure for high power charging at places with public access like motorway service stations is essential for a wide utilization of electric vehicles. This paper deals with different concepts to integrate quick charging stations in power grids of weak infrastructure areas.

This paper presents a control technique for smoothing voltage oscillations in the sub-modules of Modular Multilevel Converter during start-up operations of high-power medium-voltage induction motor drive. At steady-state, the power fluctuations in each sub-module at fundamental and 2nd harmonic frequencies generate capacitor voltage oscillations which are much higher as the current frequency decreases and tend to infinite at zero frequency. This is a problem in variable speed drives, where very low frequency values are needed during start-up. The control injects a homopolar component of the converter output voltage and an alternative high frequency circulating current, whose magnitude is much higher than the induction motor one during start-up operations. A space vector modulation technique is used in the control implementation. A numerical investigation is carried out with reference to some relevant cases-study in order to show the validity of the proposed control which allows an effective reduction of voltage oscillations on the dc-link capacitors of the different converter sub-modules.

For a rural microgrid requiring simplicity and robustness, a flywheel-generator combination directly coupled to the grid offers both energy storage and inherent stability. The tradeoff of using a directly-coupled flywheel with a constant moment of inertia is that the amount of energy extractable from within the narrow band of synchronous speeds is limited. Furthermore, a large amount of unusable energy remains within the flywheel below the grid's minimum frequency. By using a flywheel with a variable moment of inertia, although the nett energy may be less, the extractability can be increased by straightforward design. This paper presents the concept of a liquid-based flywheel where the moment of inertia is engineered to be a function of speed by appropriately sizing and shaping the liquid's spinning container.

Cold rolled non-oriented (CRNO) electrical steel sheets are soft ferromagnetic materials which are commonly used for electromagnetic core design for AC rotating electrical machines. When these materials are exposed to time-varying magnetic fields, the iron losses occur. These losses represent the power dissipated in the ferromagnetic material and they are dependent upon the frequency and magnetic flux density level of the applied time-varying magnetic field. In order to achieve high-efficiency electrical machines, especially at high operating frequencies and magnetic flux density levels, iron losses should be kept as low as possible. This imposes the need for more accurate iron losses models, but also for fast and reliable estimation techniques. This paper considers the applications of an artificial neural network (ANN) and a genetic algorithm (GA), based on the classical iron losses separation formulation for a fast estimation of the specific iron losses in CRNO electrical steel sheet grade M530-50A over a wide frequency and magnetic flux density range. Iron losses measurement data, provided by the manufacturer, are used to calibrate the iron losses models. The approaches were verified using the manufacturer's measurement data. Acceptable accuracy was obtained.

This paper presents two methods applied in the context of surveilling and localizing electrical arcs which usually occur in photovoltaic power systems. The wavelet analysis has proved to be very powerful in transient signal detection, namely in multiscale edge detection, thereby we use this method to detect the electrical arcs and to localize them in time. Secondly, we applied the recurrence plot analysis (RPA) which presented succesful results in partial discharge time localization. In order to obtain the space localization of the electrical arc, we used the time-of-arrival of the arc at the acoustic sensor system. The system is composed of four sensors and the space localization is based on time difference of arrival, resulted from the time detection based on wavelet analysis and on RPA method.
