Power quality assessment of different load categories [PDF]

, 2017
In this paper, a fuzzy logic based method is proposed to define and evaluate power quality indices for different categories of electricity consumers. The severity level of each power quality disturbance is first estimated according to the frequency of ...

Powerful Problems for Powerful Qualities [PDF]

Erkenntnis, 2019
AbstractThe powerful qualities view of properties is currently enjoying a surge in popularity. Recently, I have argued that the standard version of the view (associated with C.B. Martin and John Heil) is no different from a rival view: the pure powers position.

Data-Driven Assessment of the Impact of Solar Photovoltaic Generation on Distribution Network Harmonic Distortion

Solar
As the penetration of distributed energy resources (DERs) continues to increase, there is conjecture concerning the power quality implications of the inverters used to interface these DERs with low-voltage (LV) electricity supply networks.
