Impact of unbalanced grid conditions on PV systems
IEEE PES General Meeting, 2010With more and more photovoltaic (PV) panels, energy storage devices and other small generators being put into service, it is necessary to integrate them into power systems. Grid integration provides a reliable means for customers to use renewable energy such as solar at its maximum and to use other sources as backup.

Study on grid feed forward strategy under Unbalanced Grid Condition
2019 14th IEEE Conference on Industrial Electronics and Applications (ICIEA), 2019In the case of unbalanced power grid, the disturbance of the power grid is introduced into the feed forward accurately, thus, the output feed-forward part of the inverter is in perfect agreement with the unbalanced power grid, in order to achieve good and effective control of the current of the converter in the dynamic change of the power grid.

Control strategy for inverter in a micro-grid under unbalanced grid condition
2016 IEEE Conference on Technologies for Sustainability (SusTech), 2016Micro-grid is gaining momentum as it addresses grave concerns like climate change and energy security. This paper presents power flow control algorithm for voltage source inverter used in a micro-grid under unbalanced grid conditions. Energy Storage and local energy source are the key components of the micro-grid that is required to help stabilize grid.
