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 ...

VSG Current Balance Control Strategy Under Unbalanced Grid Voltage
2019 22nd International Conference on Electrical Machines and Systems (ICEMS), 2019In recent years, countries around the world have been vigorously developing new energy and electrifying new energy sources. As a result an increasing number of power electronic devices appear in the grid which makes the power grid develop toward low inertia and low damping.

Voltage source converter control under unbalanced grid voltage conditions
2017 XXVI International Conference on Information, Communication and Automation Technologies (ICAT), 2017This paper proposes a novel control method for voltage source converter (VSC) connected to grid under unbalanced voltage conditions. The method is based on utilizing the full control capabilities of the switching converter. The proposed method makes the voltage source inverter (VSI) supply the voltages according to the requirements of the load and/or ...

Unbalanced voltage compensation in low voltage residential AC grids
2016 IEEE Energy Conversion Congress and Exposition (ECCE), 2016This paper describes the design and test of a control algorithm for active front-end rectifiers that draw power from a residential AC grid to feed heat pump loads. The control algorithm is able to control the phase to neutral or phase to phase RMS voltages at the point of common coupling. The voltage control was evaluated with either active or reactive
