Abstract On the basis of traditional cobweb model and price theory and from practice of the operation of the energy economic system,a nonlinear time delayed differential system for energy price adjustment is established,with energy demand function as nonlinear function and energy supply function as linear function.Applying the main monomial analysis method and Hopf bifurcation theory to analyzing the equilibriumpoint of the system,the locally stable or periodically oscillations by adjusting parameters are found.The conditions,under which the equilibrium point is locally stable or Hopf bifurcation occurs,are given.The relevant conclusions for energy economic system are reached.
