V2V energy trading Considering User Satisfaction under Low-Carbon Objectives via Bayesian Game

引用

Journal of Power and energy Engineering 2023年第12期11卷 15-35页

作者： Yue Yu Yu Liu Xiang Feng Huaichao Wen School of Rail Transit Hunan University of Technology Zhuzhou China

In response to the additional load impact caused by the integration of electric vehicles (EVs) into the grid or microgrids (MGs), as well as the issue of low responsiveness of EV users during vehicle-to-vehicle (V2V) power exchange processes, this paper explores a multi-party energy trading model considering user responsiveness under low carbon goals. The model takes into account the stochastic charging and discharging characteristics of EVs, user satisfaction, and energy exchange costs, and formulates utility functions for participating entities. This transforms the competition in multi-party energy trading into a Bayesian game problem, which is subsequently resolved. Furthermore, this paper primarily employs sensitivity analysis to evaluate the impact of multi-party energy trading on user responsiveness and green energy utilization, with the aim of promoting incentives in the electricity trading market and aligning with low-carbon requirements. Finally, through case simulations, the effectiveness of this model for the considered scenarios is demonstrated.

第40届中国控制会议

作者： Hengdu Hu Bing Wang Shiqin Yang School of Mechatronic Engineering and Automation Shanghai University

This paper studies the energy trading between the interconnected microgrid, considering the uncertain electricity price of the microgrid and main grid for energy trading, we design a robust energy trading strategy, which not only considers the individual interests of the microgrid, but also enables the microgrid participating in the energy trading to get a fair share of the benefits from the cooperation. The uncertain electricity price is described by discrete scenarios. In order to give consideration to the optimization and conservatism of the solution, a robust optimization method based on the threshold of bad scenario set is used to consider more bad scenarios. To solve the robust energy trading model, an alternating direction method of multipliers based on the update of bad scenario set is proposed. The final experimental results show that the robust energy trading strategy based on the threshold of bad scenario set can reduce the total operating cost of the society by 11.11%, and the cost of a single microgrid can be reduced by 15.36% at most.

Considering that energy trading might not completely absorb excess renewable energy, we propose a multi-energy management framework including fuel cell vehicles, energy storage, combined heat and power system, and renewable energy to further realize the local absorption of renewable energy and enhance the economic benefits of microgrids. In order to reduce the influence of multi-energy coupling, stochastic renewable energy generation and energy demand, this paper designs a joint energy scheduling and trading algorithm based on Lyapunov optimization and a double-auction mechanism to optimize the long-term energy cost of each microgrid. Coupling with the auction mechanism is a dynamic, efficient energy trading and scheduling algorithm, which carefully decides the valuations of energy in the auction, optimally schedules energy, and judiciously purchases and sells energy on the current electricity prices. Simulations based on real data show that each individual microgrid, by carrying out the proposed algorithm, can achieve a time-averaged profit arbitrarily close to an optimum value while not compromising its own comfort.
