The IEEE New England Power Grid Model consists of buses and generators. When a damped oscillator is subject to a damping force which is linearly dependent upon the velocity, such as viscous damping, the oscillation will have exponential decay terms which depend upon a damping coefficient. Using MATLAB to plot the graphs from time 0 to time 20. We could then employ MATLAB to design a new controller in order to, for example, dampen out the oscillation in the response.
