Abstract

A power system is continuously subjected to a variety of disturbances. These may vary from minor events like small and random load changes to major events like faults and line tripping. It is desirable that a power system should be stable (i.e., settle to an acceptable steady state condition) without exceeding equipment ratings. Consequently, the dynamic behavior of a power system has an important bearing on satisfactory system operation. The dynamic behavior of the power system can be described by a set of differential equations. With modeling simplifications they are usually formulated as differential algebraic equations (DAEs) as follows:
$$\dot x = f\left( {x,y,u,t} \right)$$
(12.1)
$$0 = g\left( {x,y,u,t} \right)$$
(12.2)
where:
  • x represents states of the system

  • y represents variables which are algebraically dependent on x

  • u represents inputs

  • t represents time
