Reactive Compensation Planning in Unbalanced Electrical Power Systems
Energies, 2022 This research focuses on finding the optimal location of reactive compensation in an unbalanced electrical power system (EPS). An EPS is named unbalanced when there is uncertainty in the behaviour of the power demand, which causes changes in the voltage ...

Balance control of grid currents for UPQC under unbalanced loads based on matching-ratio compensation algorithm [PDF]
Journal of Modern Power Systems and Clean Energy, 2018 In three-phase four-wire systems, unbalanced loads can cause grid currents to be unbalanced, and this may cause the neutral point potential on the grid side to shift.

IET Power Electronics, 2023 Abstract This paper explores a transformerless static synchronous series compensator (TL‐SSSC) for mitigating voltage distortion in a power distribution line with renewable generations. A novel deadbeat current control scheme with time delay compensation is proposed which models the a‐b‐c three phase line with TL‐SSSC plus its LC ...
