Distributed inter-area oscillation damping control for power systems by using wind generators and load aggregators

Robust Power Oscillation Damping by DFIG Wind Turbine using Mixed H2/H∞ Control

The robust power oscillation damper (POD) design for doubly fed inducting generator (DFIG) based on a mixed H2/H∞ control method is proposed in this paper. A practical 2-order lead/lag compensator with local input signal is chosen as the POD structure. The POD is additionally installed with the voltage control loop of DFIG so that the modulation of reactive power output can be performed to damp...

Design of Wide-area Damping Control Systems for Power System Low-frequency Inter-area Oscillations

Predicting, controlling and damping inter-area mode oscillations in Power Systems including Wind Parks

This paper shows a simple approach to predicting, controlling and damping inter-area mode oscillations. In the case of a stable operating point with a poorly damped oscillatory mode, the objective is to increase the damping of that mode. That is, the power system linearization at the operating point is modified. Operator actions such as redispatch, varying load, varying reactive power (voltage)...

Damping of Inter-Area Low Frequency Oscillation Using an Adaptive Wide-Area Damping Controller

This paper presents an adaptive wide-area damping controller (WADC) based on generalized predictive control (GPC) and model identification for damping the inter-area low frequency oscillations in large-scale inter-connected power system. A recursive least-squares algorithm (RLSA) with a varying forgetting factor is applied to identify online the reduced-order linearlized model which contains do...

PMSG Based Wind Turbines Control for System Inertial Response and Power Oscillation Damping by Fuzzy

To enhance the inertial response and damping capability during transient events this paper investigates an improved active power control for variable speed wind turbines. The optimized power point tracking (OPPT) controller, which swings the turbine operating point from the maximum power point tracking (MPPT) curve to the virtual inertia control (VIC) curves by the frequency deviation, is propo...
