The increasing penetration of wind generation impacts the reliability and stability of power systems. This paper investigates and analyses the effect of PID controller parameters on the inertial response of a doubly fed induction generator (DFIG) wind turbine to support the frequency control of a power system in the event of sudden power changes. The goal of this review is to extensively determine...
The increasing level of wind power integration using doubly fed induction generators (DFIGs) has implications for local frequency support as a consequence of decoupling between DFIG rotor speed and grid frequency. To ensure reliable and stable power system operation with DFIG integration, supplementary inertial control strategies are required. Conventional inertial control algorithms which use the...
The increasing penetration of modern wind plants may cause primary frequency regulation to fall below acceptable levels, especially in isolated grids. This paper investigates the contribution of variable speed wind generators to short-term frequency support. First, the extractable inertial power from a DFIG wind turbine is quantified. Based on that, a controller is designed to transiently release...
The paper examines two major implementations of inertial response in variable-speed wind turbine generators. Through time-domain simulations, these supplementary loops are compared based on their impact on grid frequency and the wind plant. Testing is performed on an isolated, hydro-dominated power system benchmark, to which a DFIG-based wind plant is connected. The results show that when these implementations...
