Light flicker can be caused by interharmonics because these components are able to introduce fluctuations both in rms and peak value of supply voltage. The IEC standard flickermeter was deigned, for historical reasons, only with reference to amplitude voltage modulation that is

On the other hand, electrical signature of sources and loads is the unique generation/consumption pattern intrinsic to each individual electrical appliance/piece of equipment. So, this paper, starting from the analysis of the disturbance impact of a 20 kW grid connected PV system, performs a preliminary study on building a method to better understand and explore the nature of electricity generation patterns of PV plants. Through this knowledge, it is possible to explore and develop innovative applications to achieve better utilization of resources and develop more intelligent ways of operation in new smart grids.

The PLADC is a new special converter, where the transfer characteristic is a programmable piece-wise linear line, suitable for smart sensor applications. New tests have been developed, because the converter nonlinear characteristic precludes the straight application of standard techniques

A PSPICE model is presented to simulate the high frequency behavior for the disturbance propagation towards the electrical supply network. The experimental results show a good agreement with the emission model

This entails the spread of transducers with suitable frequency bandwidths, as required by the relevant standards. The paper describes a real time compensation method for the extension of the frequency bandwidth of medium voltage dividers whose performances do not allow to perform measurements over a wide frequency range. This approach will contribute to keep the costs of this innovation low.
