To Store or Not to Store: A Q-Methodological Study into the Influence of Perceived Needs and Factors on the Implementation of Electrical Storage Applications in the Dutch Power Grid

Modern society is highly dependent on the reliable supply of affordable electricity. To ensure a sustainable future, this energy should be derived from renewable generation systems. The intermittent output of such systems makes it hard to maintain the so-called grid balance, which can lead to the malfunctioning of the current power grid. Adding...

Vibration energy harvesting: Optimal non-linear motion

An increased amount of work is done towards opti- mizing the mechanical design of vibrational energy harvesters in order to cope with varying ambient conditions. Here the performance of a piezoelectric energy harvester with varying non-linear spring characteristics is modelled and experimentally veri- fied, determining the optimal non-linear...
