| Abstract: |
| Grid-friendly wind turbines based on grid forming control have been widely studied in recent years because of their advantages, such as black start, grid support and operational capability in a weak grid. To explore the operational performance of different grid-friendly control strategies in different scenarios, this paper takes a full power direct drive wind turbine as the research object and summarizes four typical grid-friendly control strategies. Based on the structures and characteristics of different control strategies, it builds the corresponding grid-friendly wind turbine models on PSCAD/EMTDC. Then, the operational performance of different control strategies is investigated in seven operating conditions, namely black start, wind speed change, load shedding, frequency support, voltage support, fault recovery and fault current limiting. Finally, the control strategy with optimal overall performance is obtained by synthesizing the simulation results in different conditions. |
