Time : 13:00 to 16:00
Location : CiTG Collegezaal C (Stevinweg 1, 2628 CN Delft, Tel. : +31 (0)15 27 89802)

In conventional aircrafts, several power systems are in operation - electrical, mechanical, hydraulic and pneumatic either used independently or as a combination. However, all of them suffer from disadvantages, including the sacrifice of total engine efficiency in the process of harvesting a particular energy such as with hydraulic and pneumatic systems. Hence, an energy transition to electric with a view to reduce emissions, decrease fuel consumption and reduce emitted noise has resulted in a stepwise development of a more-electric and hybrid aircraft to an all-electric aircraft. Such a transition is expected to provide dramatic improvements in reliability, maintainability, emissions, supportability and operations/support cost as well as enhancements in efficiency, aircraft weight and volume. This symposium brings in experts in this domain to speak on this important topic with electrical drives for aircrafts powered by green energy as the main point of discussion.

Title: Demand Response and Storage Operation in DC Distribution Grid, 
A Decentralized Approach

Venue: Van der Poelzaal LB01.220, at 13.30
The main objective is to develop general applicable Demand Response solutions and concepts, that can be used in a decentralized way first to increase the reliability of the grid, as is the case with Voltage Dependent Demand Response and secondly to provide an insight of the effect of the operation of storage devices on electricity prices, as is the case with the use of Model Predictive Control on Energy Storage Systems. Moreover, the means to experiment on these solutions under lab conditions are provided, with the construction of a Dual-Active Bridge power converter and its control module.

13th Oct 2015 - Energy Break with Prof. Pavol Bauer and Tesla Supercharger Team

Energy Club of TU Delft is an organizing its second edition of Energy Break this year - The Energy Break with Prof. Pavol Bauer and Tesla Supercharger Team! 

Tesla’s goal is to accelerate the world’s transition to electric mobility with a full range of increasingly affordable electric cars. They are catalyzing a change in the automotive industry and understanding that transitioning the world to electric mobility depends on efficient vehicle technology, convenient charging solutions, sustainable energy sources, and storage solutions for intermittent energy.
To give an overview of the scientific background, Prof. Pavol Bauer as the head of DC Systems, Energy Conversion & Storage group, ESE TU Delft will give an introduction to the technology as well as the development of current fast-charging project development in TU Delft. The talks will be concluded with an informal drinks session so that you can directly address your burning questions to the speakers.

'Highway of the future' proposal amongst top 15

Our proposal for STW Open Mind selection programme ‘Self-generating, inductively powered and healing highway’ is amongst the top 15 of 132 applications and will be presented at STW annual conference. Hereby the summary and the proposed solution. A big thanks goes to Prasanth Venugopal for help with the proposal.

Summary

The innovation and challenge is in a combination of different promising technologies – wireless inductive power transfer (IPT) for electric vehicles (EVs), self-healing roads and solar roads in the highway of 2030. Research in electrical engineering at TU Delft considers the multi-spectral highway transition in terms of energy sources, its utilization in EVs and also road healing. In electrical engineering at Delft, pioneering research in both stationary and dynamic vehicle charging using inductive power transfer is being carried out. On-road powering of EVs is a promising energy transfer technology. Here, small packets of electromagnetic energy is transferred to EVs using induction coils on the road. This way, a massive reduction in battery size, range extension and accelerated electrification of transportation becomes possible. At civil engineering, the self-healing road technology involves incorporating magnetic materials in the roads that can be heated using induction to ‘heal’ potholes. This reduces the road maintenance requirement considerably. As such, induction heating for ‘healing’ needs specialized and expensive equipment with a very low utilization factor. As a unique combination, at electrical engineering, we expect to develop the world’s first concurrent induction healing and induction powering technology for EVs. Also, emergency lanes in such a highway can be made of Solar roads (TNO Technology) to capture solar energy. This combination opens many questions including technological feasibility for both powering and healing, economic viability, safety issues and reliability of the combined technology. 

Proposed solution

A combined energy producing and utilizing highway with modular solar roads, self-healing asphalt and inductive power transfer for power transfer and road healing is shown in Fig.  1. Here, Solar energy from the sun is translated to electrical energy. This is pumped into the induction coils that are embedded beneath the top layer of the road. Induction can transfer the energy magnetically to a charge pad that is present beneath the chassis of the car. The principle of induction can also be concurrently used for healing the cracks that are present in lanes. In addition, research shows that there is high probability of crack development in load centers – near wheels. Thus, a sandwich road with self-healing asphalt is depicted in Fig.  1. The development of such a road happens in a modular fashion. The electromagnetic energy can be shaped to either transfer power to the EVs (primary objective) and when required, ‘healing’ (secondary objective). Also, at stoplights, due to repeated acceleration-deceleration cycles, the top road layer suffers extensive damage. This also happens to be the spot where vehicles are stationary for a long period of time and justifies IPT due to large energy transfer. If the technical and economic challenges of the technology are assessed, a strong patent can be applied and this technology will be a winner for future highways.  

 

30th Sept 2015 - MSc thesis defense of Nil Chaudhuri

Title: Power Balance Control of DC Microgrids 

 The aim of this MSc Thesis was to achieve power balance control in decentralised way. First, a control algorithm was developed to provide stable robust operation for the grid incorporating features from different control techniques; second, was implementing this algorithm to already present technology and perform real life analysis; third, was to develop a hardware specifically for the ease of using this and many other techniques. In the end the algorithm was tested under multiple scenario and experiments were carried out to assess the viability

The defense is on Wednesday 30th September at 14:00, room Lipkenszaal, LB01.150.

30th Sept 2015 - MSc. Defense of Natalia Scheele

MSc. Student Natalia Scheele who worked on an interdisciplinary project involving the faculties of Electrical Engineering (EWI) and Industrial Design (IDE) will defend her thesis. The following are relevant information for the thesis.

Thesis Topic: The green energy highway with on-road contactless power transfer.

Venue: Bernd Schierbeek Hall, IDE at 15:45

Summary: The thesis involves the vision of a future highway for the Netherlands in 2030. The project involves the introduction of Inductive Power Transfer (IPT) to the highway A12 which is sourced from Renewable Energy sources close to the highway. The concept of self-healing roads (CiTG) , along with IPT and renewable energy forms the theme of the work. A transitory scenario of EVs and autonomous EVs are also considered in the study. Sizing of solar panels along the sound barriers and Solaroads (TNO Technology) in the emergency lanes are considered. In case of wind energy, conventional turbines and 'Vortex' are evaluated. A detailed estimation of the location of the coil sections is detailed in the work. Finally, a holistic economic feasibility analysis is presented for the introduction of this revolutionary vision.
