Clean energy challenge requires an integration of high level measurement and control devices for monitoring and automation of electrical networks, distributed generations and storage systems into the smart grid paradigms. Sensible data are exchanged among central control systems and remote devices, whose communication link reliability is of most importance. To this aim, this paper proposes to use ...Show More
This paper presents the implementation of gapless harmonic analysis on a commercial microcontroller device, according to IEC 61000-4-30 Class A and IEC 61000-4-7 Class I requirements. The final aim is to investigate the feasibility of accurate power quality (PQ) measurements with low-cost metering platforms, to enable the capillary diffusion of PQ monitoring for smart grids applications, including...Show More
This paper presents a sensitivity analysis concerning the measurement of some time-domain parameters previously proposed by authors for series arc fault detection in electrical circuits. The parameters under study were introduced in an earlier paper; their formulation is based on current signal acquisition and processing, by means of cross-correlation analysis between subsequent cycles of the curr...Show More
Power line communication (PLC) technology is exploited worldwide for automatic meter reading on low-voltage networks. On the contrary, it is not used at medium voltage (MV) level, where it requires dedicated and costly PLC couplers. To face this issue, in previous works the authors investigated the possibility of reducing costs by coupling the signal by means of elements already installed in MV ne...Show More
The paper presents a systematic analysis of nonprogrammable distributed generation impact in an islanded microgrid Different issues have been analyzed, with a special focus on the most significant ones in a small islanded network. To this aim, the case study of Ustica island was considered A digital twin of the MV network was developed starting from the network topology data and the power measurem...Show More
This paper presents a study on the use of power factor indicators for the assessment of harmonic distortion sources in power systems. In detail the analysis is focused on the comparison between the proposed nonactive power factor (Q1/N) and the indicators of the IEEE Std. 1459-2010, and on the indicators feasibility in identifying the presence of harmonic distortion sources. As discussed in the pa...Show More
(Abstract) This paper proposes a new power line communication (PLC) architecture for monitoring and remote control of Distributed Generators (DG) and Energy Storage Systems (ESS) connected to low voltage distribution networks. The final aim is to improve the performance of the PLC link in terms of robustness and efficiency in devices addressing. The proposed solution is based on a concentrator, to...Show More
The widespread presence of distributed generators (DGs) and storage systems (DSSs) in electricity grids has increased the risk of islanding occurrence. This phenomenon must be suitably managed by Distribution System Operators (DSO), in order to avoid adverse situations, in terms of grid-protection problems, equipment damage, safety hazards, power quality problems and so on. Currently anti-islandin...Show More
The paper focuses the attention on the comparison of two approaches for power quality assessment in the electric grid. Both approaches are suitable for investigating the harmonic pollution source and discovering if the harmonic source comes from the customer or the utility grid. The two approaches have the same purpose but they are deeply different. The first approach is based on the knowledge of ...Show More
