Neutral conductor current in three-phase networks with compact fluorescent lamps [PDF]

open access: yes, 2013
In this paper, expressions of the neutral conductor current in three-phase networks with compact fluorescent lamps (CFLs) are obtained from a CFL “black-box” model proposed in the literature.

Study on the influence of three-phase voltage unbalance on electromagnetic performance and vibration of high-voltage line-start permanent magnet synchronous motor [PDF]

open access: yesArchives of Electrical Engineering
Since the operation of the high-voltage line-start permanent magnet synchronous motor (HVLSPMSM) does not need the control circuit and is directly powered by the grid, its operating stability is easily affected by the three-phase voltage unbalance. Thus,

Voltage unbalancing reduction in a stand-alone ac-dc hybrid microgrid based on floating compensation reference [PDF]

open access: yesInternational Journal of Industrial Electronics, Control and Optimization, 2020
A hybrid AC-DC microgrid consists of an AC and a DC subgrid that are connected to each other through an interlinking converter (IC). The main function of an IC under islanded conditions is to transfer power between the two subgrids.

A convex formulation for voltage unbalance compensation problem on hybrid microgrids

open access: yesRevista Principia, 2019
Voltage unbalance is a power quality condition that arises due to the presence of unbalanced single-phase loads. The presence of voltage unbalances affects negatively a series of sensible equipment and, therefore, is undesirable.
