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) ...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.展开更多

文摘为解决大量电动汽车(electric vehicle,EV)接入电网或微电网产生额外负荷冲击的问题,提出了一种基于广义纳什议价(generalized Nash Bargaining,GNB)理论的电动汽车交易模型。在市场中选择将配电网络(distribution network,DN)运营商作为代理,并在配电网络中安装变压器和并联电容器。DN运营商可通过变压器和电容器上的有载分接开关来管理网络上的电压和无功功率(voltage and reactive power,Volt-VAR)。同时,市场中允许两种交易方式,一种是EV直接与DN进行交易,另一种是电动汽车之间以点对点(peer to peer,P2P)的方式进行能源交易。最后,将GNB问题分为两个子问题,即社会福利最大化问题(P1)和能源交易问题(P2),通过调用遗传算法对P1和P2进行求解。结果表明,加入Volt-VAR后,社会福利得到了增加,参与市场的各个代理也获得更公平的利润分配。所提出的模型促进了电动汽车之间的能量交易,降低了电动汽车无序充电对电网的冲击。
