| Abstract: |
| This paper presents a novel composite wide area control of a DFIG wind energy system which combines the
Robust Exact Differentiator (RED) and Discontinuous Integral (DI) control to damp out inter-area oscillations. RED
generates the real-time differentiation of a relative speed signal in a noisy environment while DI control, an
extension to a twisting algorithm and PID control, develops a continuous control signal and hence reduces
chattering. The proposed control is robust to disturbances and can enhance the overall stability of the system. The
proposed composite sliding mode control is evaluated using a modified benchmark two-area power system model
with wind energy integration. Simulation results under various operating scenarios show the efficacy of the
proposed approach. |
