Abstract:
This article proposes an adaptive controller in a
deregulated power system for generation related ancillary
services. In an interconnected power system, due to the
intense participation of Gencos, the frequency and tie-line
responses become aggressive in nature, which in turn affects
the ancillary services in the power system like AGC. The
ANFIS controller is designed here using MATLAB –
Simulink for a five area control structure, in order to retain
the balance between the generation and demand and also
the steady state error of the proposed control area. The test
system constructed with Thermal-hydro-Gas power
generations and the performance of the controller is
evaluated by applying large load disturbances and sudden
perturbations with nonlinearities like Generation Rate
Constraint (GRC) and Backlash. The simulated results show
that the proposed control strategy provides better
performance for this large interconnected power system in a
deregulated environment.
