6 FAQs about [Primary and secondary wind in thermal power generation]

Why do we need variable speed wind turbines?

Increase of converter-connected renewable power generation such as variable-speed wind turbines (VSWTs) decreases the system inertia constant, which reduces the frequency stability of the power system. Thus, it will be necessary to include these renewables in the inertial response and primary frequency control (PFC) of future power systems.

Do wind farms support primary frequency control?

Wu L, Infield DG (2013) Towards an assessment of power system frequency support from wind plant—modeling aggregate inertial response. IEEE Trans Power Syst 28 (3):2283–2291 Wang H, Chen Z, Jiang Q (2015) Optimal control method for wind farm to support temporary primary frequency control with minimised wind energy cost.

How are wind farms compared to conventional power plants?

Do wind farms need tertiary frequency control?

In most of other grid codes, wind farms usually only participate in tertiary frequency control, i.e. they must curtail their output power when there is an excess of generating power in the system. However, it is to be expected that other TSOs will start to impose inertial response requirements on wind farms [ 5 ].

What is a secondary frequency controller based on a supervisory wind farm?

Schematic diagram of load-frequency control loop A secondary frequency controller based on a supervisory wind farm control system (SWFCS) fully utilizes the secondary frequency reserve to follow commands from system operator, including AGC commands (updated power set point) and power flow adjustment [50, 64].

Does wind power play a role in system frequency regulation?

Abstract: With the increase of wind power penetration in the electric grid, the frequency regulation method that simply reply on traditional power is gradually weakened. For this reason, the participation of wind power in system frequency regulation has become an inevitable trend in the operation of large-scale grid-connected power system.
