In this paper a hybrid differential algebraic equations (HDAEs) approach is developed for modeling interconnected power networks. After some theoretical aspects, the differential algebraic equations (DAEs) that describe the dynamics of a 4-Bus power network is obtained. Then a HDAEs model is proposed to simulate the hybrid behavior when the line tripping of one of the network lines occurs, making the system to operate in two different modes.
