Abstract

The major changes in the load, frequency, terminal Voltage, active power, reactive power, fault in the system are the major root causes for the sudden changes. The oscillation due to sudden change in the Power System will causes as unstable condition in the Generating system. This oscillation must be damped out at the earliest. Oscillations are ruled by the Power System Stabilizer. The Power System Stabilizer can be designed with various optimization techniques. The optimized output of the PSS must damp the oscillation in a short duration without disturbance in the generating system. The design was performed with conventional method, Genetic Algorithm and output is evaluated against by Grasshopper Optimization Algorithm output to get fast response from  Power System Stabilizer in order to maintain the power system with dynamic stability.
