Abstract. Lyapunov stability theory is a general and successful approach. Despite this, there is no general method for obtaining Lyapunov function. Some approaches to constructing Lyapunov functions are suitable. In this work, we focus on providing a suitable candidate Lyapunov (energy) function by using the variable gradient method based on Lyapunov’s second method. In addition, the stability region of the energy function is analyzed and visualized for two-machine infinite-bus power system. The results show that energy function can be used to obtain best estimates of the stability region.
