An analysis of the impact of plug-in hybrid electric vehicles on power system stability

Abstract

Rising gas prices, carbon constraints, fuel economy standards, and the desire for energy independence are driving the development of PHEV which are expected to achieve the equivalent of 100miles per gallon of gasoline. If they achieve significant market potential, they will have a huge impact on the electric industry, increasing load by an amount which could put the grid at risk. The challenges faced by today's power system are severe. It is designed for moderate load increase due to long time investments in electricity generation, lines and cables but faces in the future a large new load with different patterns. This paper investigates the stability of system by using the potential energy generated at and around the equilibrium points and an analysis of the stability of the power system using stochastic energy-like Lyapunov function.
