Coordinated Damping Control Design for DFIG-Based Wind Generation Considering Power Output Variation

This paper focuses on a new optimization technique of robust power oscillation damper (POD) for doubly-fed induction generator (DFIG) wind turbines considering N-1 outage contingencies. The POD with 2 nd -order lead/lag compensator and local input signal is placed with the voltage controller of DFIG so that the reactive power output can be modulated to damp out power oscillations. The optimization of POD parameters is formulated based on a mixed H 2 /H control, and carried out under all system outage events such as line tripping, and load/generation shedding etc. The firefly algorithm is employed to obtain the optimal parameters of POD. Simulation study in an IEEE 9 bus system reveals that the proposed robust POD provides superior damping effect than the conventional POD against various system contingencies and uncertainties.

“…This may cause the destruction of the rotor side converter and cause a voltage fluctuation of the DC bus [4], [5]. The second problem is output power fluctuation, despite of advanced control strategy applied to DFIG, the power injected by the Wind Turbine varies with the variation of the wind velocity [6].…”

Abstract. This paper presents a specific control strategy of Doubly Fed Induction Generator (DFIG) conceived for a wind turbine system operating under electrical grid disturbance. Two mains aspects related to DFIG behavior are studied: fluctuation of its output power and Low-Voltage Ride Trough capability (LVRT) of wind turbine generator system. In order to smooth the output power injected in the electrical grid and to improve dynamic behavior of a variable speed wind turbine generator system under symmetrical voltage dip, a control strategy of the Battery Energy Storage System (BESS) is proposed. Simulations have been carried out in Matlab environment, and the results validate the effectiveness of our control.

“…In addition, to achieve more stabilizing performance, the coordinated control of the PSS and DFIG with POD is required. In [11], the design technique for coordination between a PSS and DFIG with a POD considering random wind power output variation was presented by an extended probabilistic small-signal stability analysis. Study results indicated that the coordinated PSS and POD yield a higher damping effect than either the PSS or POD alone.…”

Multiple operating conditions in power systems including wind power sources significantly affect the damping of low frequency oscillation modes due to diverse generating and loading conditions, random wind speeds, line outage contingencies, etc. To cope with multiple operating conditions, this paper proposes the new parameter optimization technique of the power system stabilizer (PSS) and the doubly-fed induction generator (DFIG) wind turbine with the power oscillation damper (POD) based on the probability method. Different operating conditions are randomly generated by Monte Carlo simulation. Under the generated operating points, the particle swarm optimization of PSS and POD parameters is carried out to achieve the highest probability that the damping ratios of all oscillation modes are greater than the desired damping ratio for all operating points. Study results in the IEEE New England 39-bus system indicate that under the occurrence of faults, the PSS and POD optimized by the proposed method yield better stabilizing performance than the conventional PSS and POD over a wide range of operating points.
