Operation of Grid-Connected DFIG Under Unbalanced Grid Voltage Condition
IEEE Transactions on Energy Conversion, 2009Doubly fed induction generator (DFIG) still shares a large part in today's wind power market. It provides the benefits of variable speed operation cost-effectively, and can control its active and reactive power independently. Crowbar protection is often adopted to protect the rotor-side voltage source converter (VSC) from transient overcurrent during ...

Grid-Connected and Off-Grid Solar Photovoltaic System
2017PV systems are widely operated in grid-connected and a stand-alone mode of operations. Power fluctuation is the nature phenomena in the solar PV based energy generation system. When solar PV system operates in off-grid to meet remote load demand alternate energy sources can be identified, such as hybrid grid-tied or battery storage system for stable ...

Grid-connected photovoltaic installations
2010A grid-connected PV system is made up of an array of panels mounted on rack-type supports or integrated into a building. These panels are connected in series or parallel to achieve optimal voltage and current, and feed into an inverter transforming direct current into alternating current at a phase and at the same voltage as the grid.

Grid-Connected GaN Solar Microinverter
2018 IEEE 7th World Conference on Photovoltaic Energy Conversion (WCPEC) (A Joint Conference of 45th IEEE PVSC, 28th PVSEC & 34th EU PVSEC), 2018GaN-FET-based solar microinverter using a differential-mode inverter (DMI) topology is presented. Key features of the DMI topology and its switching scheme are outlined and how the GaN-FET technology affects the power-stage performance are narrated. Further, summary of the issues with grid connection are elaborated.

Reliable diagnosis of grid-connected systems
2000An efficient diagnosis algorithm for grid-connected systems is presented and evaluated The algorithm provides correct, but possibly incomplete, diagnosis if the number faults occurring in the system does not exceed a bound T_ ? returned by the algorithm itself along with diagnosis. The diagnosis may be validated by probing a very small number of units.

Grid-connected inverters (GCI) in distributed generation systems typically provide support to the grid through grid-connected operation. If the grid requires maintenance or a grid fault occurs, the inverter must operate independently of the grid. In this article, a smooth switching control strategy is proposed.
