Abstract

This paper proposes an adaptive hierarchical voltage control scheme of a doubly-fed induction generator (DFIG)-based wind power plant (WPP) that can secure more reserve of reactive power (Q) in the WPP against a grid fault. To achieve this, each DFIG controller employs an adaptive reactive power to voltage (Q-V) characteristic. The proposed adaptive Q-V characteristic is temporally modified depending on the available Q capability of a DFIG; it is dependent on the distance from a DFIG to the point of common coupling (PCC). The proposed characteristic secures more Q reserve in the WPP than the fixed one. Furthermore, it allows DFIGs to promptly inject up to the Q limit, thereby improving the PCC voltage support. To avert an overvoltage after the fault clearance, washout filters are implemented in the WPP and DFIG controllers; they can prevent a surplus Q injection after the fault clearance by eliminating the accumulated values in the proportional-integral controllers of both controllers during the fault. Test results demonstrate that the scheme can improve the voltage support capability during the fault and suppress transient overvoltage after the fault clearance under scenarios of various system and fault conditions; therefore, it helps ensure grid resilience by supporting the voltagemore » stability.« less

Flexible $$I_{Q}\!\!-\!\!V$$ Scheme of a DFIG for Rapid Voltage Regulation of a Wind Power Plant

Journal Article Kim, Jinho ; Muljadi, Eduard ; Park, Jung -Wook ; ... - IEEE Translations on Industrial Electronics

This paper proposes a flexible reactive current-to-voltage (I _Q-V) scheme of a doubly-fed induction generator (DFIG) for the rapid voltage regulation of a wind power plant (WPP). In the proposed scheme, the WPP controller dispatches different voltage set points to the DFIGs depending on their rotor voltage margins. The DFIGs inject different reactive power with the flexible I _Q-V schemes implemented in the rotor-side and grid-side converters. The I _Q-V characteristic, which consists of the gain and width of a linear band and I _Q capability, varies with time depending on the I _Q capability of the converters and amore »« less

Hierarchical Control Scheme for Improving Transient Voltage Recovery of a DFIG-Based WPP

Conference Kim, Jinho ; Muljadi, Eduard ; Kang, Yong Cheol

Modern grid codes require that wind power plants (WPPs) inject reactive power according to the voltage dip at a point of interconnection (POI). This requirement helps to support a POI voltage during a fault. However, if a fault is cleared, the POI and wind turbine generator (WTG) voltages are likely to exceed acceptable levels unless the WPP reduces the injected reactive power quickly. This might deteriorate the stability of a grid by allowing the disconnection of WTGs to avoid any damage. This paper proposes a hierarchical control scheme of a doubly-fed induction generator (DFIG)-based WPP. The proposed scheme aims tomore »« less

Adaptive Q–V Scheme for the Voltage Control of a DFIG-Based Wind Power Plant

Journal Article Kim, Jinho ; Seok, Jul-Ki ; Muljadi, Eduard ; ... - IEEE Transactions on Power Electronics

Wind generators within a wind power plant (WPP) will produce different amounts of active power because of the wake effect, and therefore, they have different reactive power capabilities. This paper proposes an adaptive reactive power to the voltage (Q-V) scheme for the voltage control of a doubly fed induction generator (DFIG)-based WPP. In the proposed scheme, the WPP controller uses a voltage control mode and sends a voltage error signal to each DFIG. The DFIG controller also employs a voltage control mode utilizing the adaptive Q-V characteristics depending on the reactive power capability such that a DFIG with a largermore »« less

Voltage control for a wind power plant based on the available reactive current of a DFIG and its impacts on the point of interconnection

Journal Article Usman, Yasir ; Kim, Jinho ; Muljadi, Eduard ; ... - Transactions of The Korean Institute of Electrical Engineers

Wake effects cause wind turbine generators (WTGs) within a wind power plant (WPP) to produce different levels of active power and subsequent reactive power capabilities. Further, the impedance between a WTG and the point of interconnection (POI)-which depends on the distance between them-impacts the WPP's reactive power injection capability at the POI. This paper proposes a voltage control scheme for a WPP based on the available reactive current of the doubly-fed induction generators (DFIGs) and its impacts on the POI to improve the reactive power injection capability of the WPP. In this paper, a design strategy for modifying the gainmore »« less

Stable Short-Term Frequency Support Using Adaptive Gains for a DFIG-Based Wind Power Plant

Journal Article Lee, Jinsik ; Jang, Gilsoo ; Muljadi, Eduard ; ... - IEEE Transactions on Energy Conversion

For the fixed-gain inertial control of wind power plants (WPPs), a large gain setting provides a large contribution to supporting system frequency control, but it may cause over-deceleration for a wind turbine generator that has a small amount of kinetic energy (KE). Further, if the wind speed decreases during inertial control, even a small gain may cause over-deceleration. This paper proposes a stable inertial control scheme using adaptive gains for a doubly fed induction generator (DFIG)-based WPP. The scheme aims to improve the frequency nadir (FN) while ensuring stable operation of all DFIGs, particularly when the wind speed decreases duringmore »« less
