Abstract
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.
Highlights
Supply-side reform has been continuously implemented in Chinese power industry [1]. e huge power market has gradually opened up, and customer can purchase electricity directly from the State Grid or power companies
Multienergy can be connected to the State Grid on a large scale. e electricity market shows a complex competition with multiple energy sources and multiple channels
The State Grid deals with multiple energy sources from power enterprises and retails them
Summary
Supply-side reform has been continuously implemented in Chinese power industry [1]. e huge power market has gradually opened up, and customer can purchase electricity directly from the State Grid or power companies. E huge power market has gradually opened up, and customer can purchase electricity directly from the State Grid or power companies. Multienergy can be connected to the State Grid on a large scale. E electricity market shows a complex competition with multiple energy sources and multiple channels. The loss in processes of transmission, substation, and distribution is the main power supply costs [2]. Reducing electricity loss is an important measure to ensure energy security and sustainable development. Erefore, considering electricity reform of China, coexistence of macrocontrol and market competition, this study builds a dual-channel supply framework for multienergy supply. Based on the goals of saving energy strategy, a line loss investment model of multichannel supply chain is proposed, and the complex characteristics of investment market in line loss are analyzed
