Do wind turbines need a safe voltage control setpoint?The wind turbines must default to a safe voltage control setpoint on failure of the master voltage controller. At higher power output, small changes in reactive power can cause large changes in voltage at PCC. This is particularly true for wind farms connected to a weak grid.
Do wind turbines support grid voltage during voltage deviations?In a power system with a high penetration of wind power generation, it is required that the wind turbines support the grid voltage during voltage deviations to ensure the system's security. After a voltage drop, the system's P – U curve is shown in Figure 2.
Why do wind power and photovoltaics lack voltage support capability?Wind power and photovoltaics in new energy power systems lack voltage support capability. As the proportion of synchronous generators (SG) decreases, the system's short-circuit capacity also decreases, leading to insufficient short-circuit ratio (SCR).
Do wind turbines with grid-forming control support voltage stability?Additionally, the MSR values during the recovery period after fault clearance also show an upward trend. Therefore, wind turbines with grid-forming control effectively support voltage stability and mitigate the risk of voltage instability associated with high wind power penetration.
What is a weak node in a power system?In a power system, a node is considered weak when the changes in its operating state significantly alter the system's overall operating condition [4, 5]. Accurately identifying weak nodes in the system and developing novel control strategies for enhancing voltage stability are crucial for ensuring system security.
How to ensure the voltage stability of a wind turbine?To ensure the system's voltage stability, there are certain requirements for the short-circuit capacity, STP at the grid connection point in the fault test experiments.
