It is a single-point strategy, based on a comparison among different "nonactive" power quantities proposed in literature, that, in the same working conditions, assume different values at the metering section. Some simulations tests were carried out on a standard IEEE test system, proposed, by other authors, as a benchmark system for the analysis of multi-point measurement techniques for harmonic pollution monitoring. The obtained results show that the proposed single point approach is in agreement with other strategies already proposed in literature and can give useful indications for the detection of the dominant harmonic source in a metering section also in some critical cases.

A simple and friendly Simulink ® software is used to develop the model. A distributed parameters MV cables model in line-line configuration is considered. Also the signal coupling networks with the generation and receiving systems are included. The performances of the complete PLC communication system are evaluated introducing the attenuation constant computed as ratio between the received and transmitted voltage signals. The signal losses produced by the complete system in the CENELEC frequency band and for different cable lengths are also considered.

The novelty of the method consists in the harmonic analysis of the supply current by means of the chirp-Z transform (CZT). The advantages are improved accuracy due to better spectral resolution and resolvability. Moreover, a shorter observation window is required, thus reducing errors related to nonstationary current signals. The experimental results are presented to validate the proposed method and to make a comparison with a similar method based on the fast Fourier transform (FFT).

As proposed has been developed in conformity with laws and standards and can be applied to active and passive secondary substations. The experimental validation of the proposed methodology, carried out by a measurements campaign whose results are reported, confirms the validity and returns a versatile and simple tool for the verification of the quality targets required by current legislation.

In this paper a pc-based power quality instrument is proposed, according to IEC 61000-4-7 and standard IEC 61000-4-30. It is a low-cost and easily reconfigurable instrument able to measure harmonics, interharmonics and amplitude disturbances and supply unbalance.

The proposed system fulfills the in-force standard requirements for the connection of DGs to the utility grid. Moreover, it allows implementing some enhanced functions for the remote control of inverters of DGs and ESSs, not only in terms of disconnection but also in terms of voltage regulation and power shuttering. The proposed solution is based on a new interface protection system and a dedicated secondary substation concentrator, which allows the communication between the distributed system operator and the inverters of DGs or ESSs. The proposed system was tested on field in the electrical network of the island of Ustica. An experimental characterization was carried out to find the best communication conditions, i.e., the frequency band with the lowest noise and attenuation, considering the signal amplitude and signal-to-noise ratio constraints, as well as the desired transmission data rate and transfer time.

This algorithm calculates directly the switching pulse patterns for the inverter devices using an expression based on the definition of the duty cycle. By means of geometric considerations the over modulation range is detected without using trigonometric functions and avoiding to calculate the hexagon sector with the advantage of a lower calculation time and an increased switching frequency. Computer simulations have been carried out to verify the performance of the developed SVM strategy. Moreover the algorithm has been tested on an AC motor drive test bench, showing how, with respect to a conventional space vector modulation control algorithm, it allows one to increase the switching frequency up to the maximum switching frequency allowed by the inverter devices used in the test.

In particular, the paper analyses the electromagnetic conducted immunity of a new interface protection device (ID) for smart grid and energy storage applications. The new ID is equipped with a measuring board, a STM32 microcontroller, for data elaboration and memorization, and a ST7580 N-PSK powerline transceiver. An experimental test procedure have been carried out in order to investigate the immunity of the ID prototype to narrowband and RF disturbances conducted disturbances, respectively for the frequency range 10-150 kHz and 150 kHz-30 MHz.

The instrument makes use of two commercial data acquisition (DAQ) boards, a non-inductive current shunt, a personal computer and a commercial software for data processing. Starting from the results of an experimental characterization of the two instrument channels with non-sinusoidal voltages and currents and a correlation analysis, the combined standard uncertainties of IEEE Std. 1459-2010 quantities are evaluated, following the approach of the ISO Guide to the Expression of Uncertainty in Measurement (GUM).

Thus, the evaluation of the performances of such equipments is required, also in the presence of disturbances affecting the power systems. With respect to this, this paper analyzes the main aspects related to the metrological characterization of the static meters for reactive energy in the presence of harmonic distortion. Particular attention is given to the reference standard meters, that are not considered by the actual in-force Standards. The analysis is supported by several experimental tests.
