This evolution makes the power system more dynamic and more distributed, with higher uncertainty. These new power system behaviors bring significant challenges in power system modeling and simulation as more data need to be analyzed for larger systems and more complex models to be solved in a shorter time period.
The linearisation of nonlinear power system models has been included in this chapter. Based on this, the linear modal analysis technique used to conduct system small-disturbance stability analysis has been outlined. This is followed by the representation of bifurcation theory, which is a nonlinear analysis approach.
