Abstract:
In this thesis a sliding mode based control algorithm is applied in load frequency control of a power system. Parameters of the proposed control algorithm are computed using genetic algorithms. To compute a control signal in sliding mode controller, a full system knowledge is required. Not all system state and disturbance components are measurable, therefore they are estimated using fast output sampling technique. Simulation research is firstly conducted on linear power system model, where a comparison of the proposed load frequency control algorithm and commonly used PI control algorithm is obtained. Simulation results show that the proposed algorithm outperforms PI algorithm. Moreover, simulation results show robustness of the proposed algorithm to presence of parameters identification error, measurement noise and variations of all system parameters. Secondly, the proposed control algorithm is tested on nonlinear power system model and its good performance is thereby confirmed.
