基于演化博弈的车网双向互动策略研究

随着电动汽车技术的快速发展，数量庞大的车载电池将成为电网削峰填谷的重要资源，制定合理的放电电价有利于调动车网双方参与互动的积极性。以电动汽车用户和电网公司收益均衡为目标，基于演化博弈理论建立车网双方演化博弈模型，研究了车网动态演化稳定过程，得到了满足双方利益需求的放电电价范围。算例结果表明：放电电价存在特定的响应范围，只有在该范围内，车网双方才可以从中受益，从而实现良性互动。可为电网公司放电电价的制定提供参考依据。

Research on Two-Way Interactive Strategy of Electric Vehicle and Power Grid Based on Evolutionary Game

With the rapid development of electric vehicle technology, the huge number of on-board batteries will become an important resource for the power grid to cut peak load and fill valley. The development of reasonable discharge electricity price will be conducive to mobilizing the enthusiasm of both sides of the vehicle network to participate in the interaction. Based on the evolutionary game theory, an evolutionary game model is established for the benefit equilibrium of electric vehicle users and power supply companies, and the dynamic evolutionary stability process of the vehicle network is studied. The case study results show that the discharge price has a specific response range, and only within this range, both sides of the vehicle network can benefit from it, thus achieving a benign interaction. This study can provide a reference for the power supply companies to formulate discharge electricity prices.
