A single-point approach based on nonactive power factor for the assessment of harmonic distortion sources in power systems
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 paper, the proposed indicator can be evaluated with good accuracy, by means of typical power quantities measurements at the point of common coupling (PCC). Thus its measurement can be feasibly implemented in commercial platforms used for smart metering applications. To verify the proposal validity, s…
Impact of non-programmable distributed generation in an islanded microgrid: the case study of Ustica
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 measurement acquired in each secondary substation. Simulations were then performed in the hypothesis of a large increment of distributed generation installation into the network. A discussion is then reported on which are the main technical issues to be faced in the considered case study.
