The electricity sector in Switzerland is undergoing important changes following the liberalisation process and the facilitation of renewable energy technologies. Furthermore, the phasing out of nuclear power will increase the demand for new domestic electr ...
The facilitation of renewable energy technologies should also consider energy storage says Nicolas Crettenand as he looks at the potential for small storage and pumped storage plants in Switzerland. ...
Efficiency and energy consumption reduction are becoming a key issue in elevation applications. Energy Storage Systems (ESS) can play a significant role on this field, together with their associated Energy Management System (EMS) in order to optimize the o ...
This paper demonstrates a novel methodology using a rotational flywheel to determine the energy conversion efficiency of the impact based piezoelectric energy harvesters. The influence of the impact speed and additional proof mass on the efficiency is pres ...
Large scale energy storage may play an increasingly important role in the power generation and distribution sector, especially when large shares of renewable energies will have to be integrated into the electrical grid. Pumped-hydro is the only large scale ...
The milling process has been continuously optimized from many aspects: forces, velocities, stability, quality. Numerous papers have been published that report results in the domain of toolpath optimization with criteria such as raising the quality of the m ...
The continuous growth of energy needs and the fact that unpredictable energy demand is mostly served by unsustainable (i.e. fossil-fuel) power generators have given rise to the development of Demand Response (DR) mechanisms for flattening energy demand. Bu ...
This paper investigates the ways to handle active power components for control and balancing purposes in three-phase Cascaded H-Bridge converters with embedded battery energy storage systems. The split storage elements are interfaced to the converter modul ...
This paper reports the design, fabrication, and testing of a soft electroactive polymer power generator that has a volume of 1cm(3). The generator provides an opportunity to harvest energy from environmental sources to power wireless sensor networks becaus ...
This paper proposes a cascade or multiloop digital control strategy for the voltage regulation of a three-phase islanded single distributed generation (DG) unit microgrid and its dedicated load. The cascade control strategy consists of an inner dq-currents ...
