摘要
目前,电力市场在新增实体和大规模电动汽车并网的影响下,交易主体呈现多元化的趋势。以博弈理论为基础,通过实验计算模拟的方式分析了电力市场的交易方式及策略选择的新形态。首先考虑了地理位置、收益及系统网损等因素,建立了电动汽车群、新增实体和电网公司多方动态非合作博弈模型。以6个新增实体和2个电动汽车群为例,采用协同进化遗传算法求解其纳什均衡解。通过算例模拟分析,验证了所提方法的合理有效性。该研究为分析电动汽车群和新增实体对电力市场多方交易决策的影响提供理论参考。
At present, the New Entities （NEs） and the large-scale Electric Vehicle （EV） access to the electricity market to participate in the electricity trading under the constantly active environment, the transaction participants present a diversification trend. Based on the game theory, this paper analyzes the transaction mode and the new form of strategy selection in the electric power market by means of experimental calculation and simulation. Firstly, considering the factors such as geographical location, revenue and system loss, the static non-cooperative game model of EV groups, NEs and grid company is established. Then six NEs and two EV groups are used as examples, the Cooperative Coevolutionary Genetic Algorithm （CCGA） is used to solve the Nash equilibrium solution. The reasonable validity of the proposed method is verified by the numerical example, which provides a theoretical reference for the analysis of the role of EV groups and NEs in multi-patty decision-making in electric power market.
