Dus (in goed Engels):
Validation (testing) is done in order to
de-risk
a component, system or technology
for its intended purpose
in a ‘risk-free’ environment,
before installing it in the real world.

… is changing fast
▪ Hybridisation (renewable energy sources, T&D, delivery and
control)
▪ Big and small technologies develop in parallel
▪ Increased system complexity and inter-dependencies

An old story of smart transformers in a greenhouse area
11
▪ Fully tested at KEMA (now DNV GL),
including short circuit
▪ Installed in greenhouse area in
Western part of The Netherlands to
improve the power quality
▪ Functioned perfectly, until a second
unit was installed nearby
▪ Started to react on each-other
resulting in instability
▪ Removed from the grid
