Research on Dynamic and Complexity of Energy-Saving Investment about Multichannel and Multienergy Supply Chain

Abstract EN

Considering the multienergy structure of the electricity market and supply-side competition reform in China, a dual-channel and multiproduct supply chain model is constructed.

There are three players in the game model: new energy company and traditional energy company provide energy for the market and the State Grid at the same time.

The State Grid is a retailer who buys electricity from two companies and supplies to the market after converting and transmitting the power.

Three companies can invest in grid management for saving energy and reducing losses.

The energy loss rate is an exponential function of line loss investment.

Through the bifurcation graph, Lyapunov exponent, and the basin of parameter, the complex characteristics of the investment market are analyzed.

It is interesting to find the Grazing–Hopf bifurcation which usually occurs in nonlinear circuits.

The mixed expectation of bounded rationality and the naive expectation is conducive to suppressing the bifurcation and chaos of the market.

When external shocks occur, the control model has good robustness.
