Incorporation of sliding mode control and PID for dynamic stability enhancement of power system
نویسندگان
چکیده
A Sliding Mode Controller (SMC) is adopted in this work with a Proportional Integral Derivative (PID) to employ instead of Power System Stabilizer (PSS). The major proposal is that the effective property of PID and high characteristics of SMC are combined to eliminate the chattering effect of SMC in order to generate best control signal to the excitation system. The robust design of SMC-PID has been employed to enhance the power system stability and further to damp out strongly the system oscillations that caused by the disturbances. The proposed proposition is evaluated on Single Machine Infinite Bus (SMIB) power system under different perturbations with prespecified operating condition. The simulation results have demonstrated the high performance of mentioned controller that attained best results compared to various controllers. Keywords— PID, Power system stability, PSS, SMC, SMIB power system.
