Intelligent Controlled Dynamic Voltage Restorer for Improving Transient Voltage Quality
IEEE Access, 2023 A dynamic voltage restorer (DVR) is developed to stabilize the three-phase load voltage under the sudden grid voltage distortion conditions, including the voltage sag, swell and unbalance.

IET Generation, Transmission and Distribution, 2018 Keeping voltage quality in isolated microgrids while feeding non‐linear and/or unbalanced loads is one of the major challenges in the control of these networks. This study proposes a new hierarchical control for enhancing voltage quality in sensitive load bus (SLB) of isolated microgrids considering non‐SLBs (NSLBs (DG buses and local buses)) with ...

Secondary Control for Voltage Quality Enhancement in Microgrids [PDF]
IEEE Transactions on Smart Grid, 2012 In this paper, a hierarchical control scheme is proposed for enhancement of sensitive load bus (SLB) voltage quality in microgrids. The control structure consists of primary and secondary levels. The primary control level comprises distributed generators (DGs) local controllers.

Voltage Control in MV Network with Distributed Generation—Possibilities of Real Quality Enhancement
Energies, 2022 Connecting an increasing number of distributed sources in MV (medium voltage) and LV (low voltage) distribution networks causes voltage problems resulting mainly from periodic power flows towards the HV/MV (HV—high voltage) transformer station.

Impact of voltage subharmonics and interharmonics on currents in single-phase induction motors
Scientific Journal of Gdynia Maritime University, 2021 In very low power drives, a single-phase induction motor is used. This motor, like the 3-phase induction squirrel-cage motor, requires a voltage supply with suitable parameters – of suitable quality, in practice.
