DISTURBANCE OBSERVER BASED OFFSET FREE MODEL PREDICTIVE CONTROL FOR LOAD FREQUENCY REGULATION IN POWER SYSTEMS

N S S RAMAKRISHNA, ELANGOVAN.D, T. S KISHORE.

Abstract
Increased renewable energy additions and load fluctuations lead to large load frequency fluctuations in power
systems. This paper proposes a nonlinear disturbance (NDO) observer based offset free Model predictive control
(MPC) for automatic generation control (AGC) in power systems. Load Disturbances and un-modeled
nonlinearities which adversely affect the output prediction in MPCare considered as a net disturbance and it is
estimated using a NDO. The estimated disturbance is included in the output prediction stage and an offset free
MPC control law is derived based on receding-horizon optimization. This proposed method of frequency
regulation is tested on single area and three area power systems and the simulation results demonstrate the
efficacy of the proposed method.

Key words: AGC; Load frequency control; Model predictive control; Disturbance observer.
