Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
Wireless power transfer technology offers significant improvement in convenience and electric safety for electric vehicle (EV) charging. Our research aims at novel designs that considerably reduce size and cost while increasing the coupling coefficient and improving the misalignment capability. We will first introduce the basics of wireless power transfer followed by discussion of a double-sided LCC...
New technologies are developing very faster than before and also technologies changed rapidly needs of people according to the use of technology. To understand the meaning of the benefits that renewable energy can bring we must firstly establish our understanding of the concept. The future of the developed and developing countries in the world depends on the availability and transport of energy. It...
Smart grid technology is the key for an efficient use of distributed energy resources. There prevails a steady increase of power demand due to urbanization and industrialization. Distributed Generation (DG), a rational idea to reduce the burden on the centralised grid and increase the grid reliability. DG gets an appealing picture when many renewable sources are integrated with one another and complements...
Meso-erythritol is evaluated as a phase change material (PCM) for medium temperature applications in an encapsulated spherical aluminium capsule. A custom made experimental setup is used to perform different charging and discharging experiments. The experiments are performed with flow-rates of 3 ml/s, 6 ml/s, 9 ml/s and 12 ml/s. The average charging rate is observed to increase with an increase in...
This paper proposes a novel energy and power management algorithm for AC microgrid operating with limited power sources, to ensure power quality and stability of the main grid. In a microgrid system, the renewable energy sources (RES) are commonly associated with conventional power sources and energy storage devices, due to the variety of the former. However, how to utilize the RES and energy storage...
Compact heat exchangers are the devices that allow having larger surface area density which is provided by the enlargement of the fins. Frequently plate fins are chosen to achieve this and several forms of this fin types are used in several applications such as rectangular plain fin offset strip fin, wavy fin, louvered and perforated fins. In this particular work, the effect of the fins on the performance...
In this work, we treat a simultaneously integrated maintenance optimization problem for a power generation system by studying the case of wind turbine. The generation system composed by a wind turbine system in order to satisfy a randomly power demand under a given service level and during a finite horizon. The goal of this work is to develop a jointly energy production and maintenance strategy optimization...
PV based distributed generators are inverter based and employ a switching scheme to inject power into the grid. The most common and commercially used technique involves the Pulse Width Modulation (PWM) controlled technique. Although PWM based technique is widely used, it is not affirmative to conclude that hysteresis controlled technique could be dismissed completely. A comparative evaluation and...
For a high penetration of intermittent renewable energy sources, they may cause transmission-line congestion problems in power systems. In particular, among the current forecasting methodologies for renewable generation, an extremely large (but rare) forecasting error in the renewable generation inevitably occurs. In a previous paper, the authors developed a line current variation model to represent...
This paper presents an interfacing system of a photovoltaic (PV) array with an electrical grid based on a dual cascaded inverter. The PV array is connected to the main inverter through a boost converter, for maximum power extraction, while the dc-side of the auxiliary inverter is connected to a capacitor bank. The main and auxiliary inverters are controlled to deliver the harvested maximum power from...
In electric distribution systems, a parallel arc is caused by a short circuit resulting from insulation breakdown of a wire or aged equipment. A series arc occurs when a load and a power source are disconnected from a connector such as a circuit breaker, a socket-plug or a coupler. In DC systems, these arcs are not extinguished unless the arc current decreases to zero. Sustaining plasma arc current...
The article concentrates on the energy storage problem arising from small scale residential electricity generation, in the current case wind micro turbine and PV panels. The research objective is to increase the locally consumed energy share by using two water tanks, aiming to shorten the breakeven periods of the renewable energy production devices. The shaved peaks from stochastic wind turbine and...
In a wave energy converter with oscillating water column (OWC), an OWC due to the sea wave motion is used to drive an air column in the air chamber. An air turbine for this bidirectional airflow is used to convert the pneumatic energy into the mechanical energy. In this study, in order to achieve further improvement of the performance of a counter-rotating impulse turbine, the effect of turbine geometry...
Solar energy can be best harnessed by obtaining accurate values of solar radiation intensity for a given location. This work describes the design and implementation of a novel dual axis tracking system, costing a fraction of an equivalent product on the market, which has been developed to measure, remotely analyze, and assess the solar radiation potential using two pyranometers and a pyrheliometer...
