Complexity, 2022 Aimed at that ubiquitous three-phase unbalance problem in low-voltage distribution networks, the spotted hyena optimizer (SHO) algorithm is used to optimize the commutation strategy of the three-phase load unbalance.

Impact of voltage unbalance on the performance of three-phase induction motor [PDF]
The South Pacific Journal of Natural and Applied Sciences, 2006 Availability of quality power has become an important issue for industrial utilities due to frequent performance variations in process industries. Increase in the generating capacity has not kept up pace of power demand, which results into shortage of power supply and power system network is normally subjected to varying and unequal loads across the ...

Research on the Device Design for Calculation Distribution Line Loss Based on Dynamic Three-phase Unbalance Degree [PDF]
E3S Web of Conferences, 2019 For the power distribution network line loss calculation, there are some problems, such as backward method, long calculation period, large workload and poor real-time performance.

Energies, 2013 For islanded microgrids, droop-based control concepts have been developed both in single and three-phase variants. The three-phase controllers often assume a balanced network; hence, unbalance sharing and/or mitigation remains a challenging issue ...

Secondary voltage unbalance compensation for three-phase four-wire islanded microgrids [PDF]
2014 IEEE 11th International Multi-Conference on Systems, Signals & Devices (SSD14), 2014 This paper proposes a secondary voltage unbalance control approach that compensate voltage unbalances in three-phase four-wire islanded microgrid systems. It is implemented in the secondary control level of the microgrid hierarchical control structure.

IEEE Access, 2022 Many unbalanced voltage conditions, which produce different effects on electric equipment, are associated with the same voltage unbalance factor. This fact hinders the precise association between the values of this index and the effects of voltage ...

IET Generation, Transmission & Distribution, 2020 Three‐phase electric vehicle (EV) battery chargers are expected to not impact the unbalance of distribution networks; moreover, using active power factor correction topologies they are expected to behave like resistive loads not affecting the system ...

The Journal of Engineering, 2021 A differentiation in three‐phase voltages or currents is termed as unbalance. Unbalance can be caused by unbalanced loads and power system faults. This disturbance results in serious problems in system elements, particularly to synchronous generators ...

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.
