Background:
This paper presents dynamic performance analysis of isolated wind-diesel
power system. A dual mode controller is proposed for pitch control of wind turbine generator.
Methods:
The parameters of the controller are optimized by Differential Evolution (DE) algorithm. The
hybrid model was simulated with the proposed load frequency controller (LFC) by considering step load
perturbation. The minimization of time multiplied integral of absolute error is considered as the
objective function. The performance of the proposed controller is compared with the published result of
the optimal controller. Further, the performance of the system is investigated by incorporating Super
Conducting Magnetic Energy Storage (SMES) and Fuel Cell (FC). Also, the dynamic performance is
investigated for changing step load perturbations. Furthermore, the response of the system is analyzed
towards random loading.
Results:
Finally, sensitivity analysis is done by varying the system parameters and operating conditions
from their nominal values.
Conclusion:
The simulation results show that the proposed dual mode DE optimized controller gives
better transient and steady state response.
