Impact of electrical car charging on unbalance in public low voltage grids
11th International Conference on Electrical Power Quality and Utilisation, 2011E-Mobility starts to become an important part of our live. Germany plans to bring 1 million cars into the market until 2020. Nowadays the cars mostly use single phase charging with charging currents up to 32A and sometimes even more. 2-phase charging is also in discussion.

Negative-sequence admittance control scheme for distributed compensation of grid voltage unbalance
2012 IEEE 13th Workshop on Control and Modeling for Power Electronics (COMPEL), 2012This paper proposes to ease the responsibility of the grid for voltage unbalance correction with distributed generation systems. Specifically, the functionality to decrease the negative-sequence voltage at the grid connection point is added to the control of distributed generation inverters.

2019 22nd International Conference on Electrical Machines and Systems (ICEMS), 2019
The combined three-phase single-stage PFC converter is a promising topology in high-power applications. However, the output voltage ripple present under grid imbalance severely affects the output characteristics of the converter. Based on this, this paper analyzes the topology and conventional control strategy of the combined three-phase single-stage ...

IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013
With a large penetration of distributed power, transmission system operators (TSO) have more stringent demands regarding the interconnection of the distributed power generation system (DPGS) to the utility grid in order to maintain a stable power system. Among the new demands, power generation systems are requested to ride through grid disturbances and

A Voltage Rise Mitigation Strategy under Voltage Unbalance for a Grid-Connected Photovoltaic System
The voltage rise due to the injection of power from a photovoltaic (PV) system into the power system network is a major problem for high penetration of PV generation. It is also observed that the voltages at the point of common coupling (PCC) are usually unbalanced due to the unbalanced loads in the system.openaire +1 more source
