Integration of DG sources for compensation of unbalanced loads in the power grid
2015 IEEE Eindhoven PowerTech, 2015Nowadays, it is a high trend to increase the electricity production using Distributed Generation (DG) technology based on renewable energy resources (RERs) such as photovoltaics and wind power. If these systems are not properly controlled, their connection to the power grid can provoke many problems on the grid side.

The control for grid connected inverter of distributed generation under unbalanced grid voltage
2009 International Conference on Sustainable Power Generation and Supply, 2009This paper describes a new control scheme of grid connected inverter of DG (distributed generation) under unbalanced grid voltage. In this paper, the proposed scheme of synchronous reference frame (SRF) controller can reduce the influence of unbalanced grid voltage, which is mainly caused by unbalanced distribution of single-phase and non-linear loads,

Flexible operation of parallel grid-connecting converters under unbalanced grid voltage [PDF]
, 2017 According to the European grid code, grid-connecting converters should always be connected to the grid under grid voltage unbalance. However, grid voltage unbalance severely affects the stable operation of the converters and leads to the various power issues, such as active power oscillation, DC-link voltage ripple, and overloading.
