Briefy put:
Calibration of e-meters is vital when operating at high frequencies with high harmonics. Failure to do so will result in incorrect measurement and readings. Simple solutions are available to measure harmonics with high accuracy.

Briefy put:
Examines the role of current interoperability standards and calls into question whether these are truly interoperable. Examining PRIME, G3-PLC, and OSGP and determining whether the interoperability is truly across the entire system, or just within a few reference layers of the whole communication model.

Briefy put: as more elements are added into the grid, power quality standards and measurement need to be reassessed to take into consideration the necessity of more refned standards.

Power systems in Central Europe are systematically facing critical situations. An enormous power market deformation (public subsidies of renewable sources, import of cheap coal from the USA due to shale gas usage) is leading to many negative impacts. Modern gas and coal power sources as well as (surprisingly) nuclear reactors are often beyond the line of economic proftability.
