Abstract

This paper considers an energy demand-supply system under the government regulation for the two regions in China. The stability properties of the equilibrium points are analyzed. Subsequently the system of energy supply and demand under government regulation with time delay has been established. Then stability of the equilibrium points is analyzed and several advantage are reflected through simulations and it is found that Hopf bifurcation appears under some conditions. By using the center manifold theorem and normal form method, we obtain the explicit formulae revealing the properties of the periodic solutions of Hopf bifurcation. Numerical simulations illustrate effectiveness of our results.
