A Voltage Support Schemes of Asymmetrically controlled Three-Phase Inverter-Based Generating Units

Abstract

Paper provides insight into possibility of asymmetrical three-phase inverter high-level control as additional grid support in low voltage networks. The asymmetrical control may assist with lowering asymmetry in areas with large single-phase load/generation penetration. Proposed and implemented control schemes are tested with laboratory equipment utilizing artificial network. Results are evaluated based on their effect on voltage asymmetry reduction and neutral conductor current magnitude.
