Power factor, voltage variations and losses: A detailed analysis of the Italian MV networks

This paper reports on a study, performed on a significant sample of Italian MV networks, aimed at the estimating the benefits deriving from the application of different limits (in terms of power factor to be respected by MV and LV final customers). The benefits obtained are evaluated w.r.t. network real losses and to power quality (in particular, supply voltage variations). Finally, a cost/benefit analysis is provided. The results show that a better reactive compensation could be a practicable way to enhance distribution networks performance. The real application of the new reactive constraints can be envisaged only within a suitable regulatory framework.
