Game Mechanism Design of Smart Contract for Thermal Power Plants Participating in Wind Power Heating

摘要

For the north of China, the wind power clean heating is of great significance that increasing the ability to consume wind power in areas with abundant wind energy resources, alleviating the difficulties of wind power integration during the trough period of power load in winter season, promoting the utilization of clean energy in cities and towns, and reducing environmental pollution caused by inefficient combustion of fossil fuels. In this paper, in the thermal power plant using electric boilers to participate in wind power clean heating transactions, considering the decentralization which is the similar point between blockchain technology and energy internet, a weakly centralized power trading center scheme based on blockchain technology is proposed to realize wind power consumption transaction, and the entire transaction process is analyzed. At the same time, this paper proposes a side-payment mechanism based on sequential games in transaction game which constructs a three-level nested game wind power consumption transaction model, and analyzes how to use game theory as a theoretical tool to improve the transaction efficiency. Finally, according to the case analysis, the existence of Nash equilibrium in the game mechanism proposed in this paper is proved, the mechanism is proved to be effective, and the influence of each factor in the transaction is analyzed.
