摘　　要：为提升近用户侧太阳能安装容量,促进太阳能光伏与光热的消纳,提出一种光伏光热耦合的热电联产系统,构建基于能源销售商—用户—系统的主从博弈理论,优化不同置信度水平下用户侧和系统侧的热电平衡关系。案例分析结果显示,使用主从博弈策略达到博弈均衡后,在置信度为0.9的工况下,需求响应后用户侧在高电价时段的用电需求平均减少763 kWh,而在低电价时段用电需求平均增加564 kWh。其中,燃气轮机在09:00时输出最大电能为2.2 MWh,光伏组件在14:00时输出最大电能为2.4 MWh,用户侧的用热需求实现31.6%的削减。通过引导系统侧的设备出力及用户侧的用能需求,系统侧产能更合理,用户侧用能更经济,各参与方均能实现自身利润的最大化。To enhance the installation capacity of solar energy at the user side,promote the integration of solar photovoltaic and thermal energy,a combined heat and power system based on solar photovoltaic and solar thermal cooperation is proposed.By introducing the concept of energy salesmen and establishing a master-slave game theory based on energy salesmen-users-system,the thermal and electrical balance between the user side and the system side at different confidence levels is optimized with the purchase and sale prices as the decision variables.Case studies demonstrate the effectiveness of the proposed method.At a 0.9 confidence level,demand response reduces the user's electricity consumption during peak price periods by an average of 763 kWh,while increasing consumption during low price periods by 564 kWh.The gas turbine outputs a maximum of 2.2 MWh at 09:00,and the photovoltaic system reaches a peak of 2.4 MWh at 14:00.Additionally,the user's thermal demand is reduced by 31.6%at 14:00.By optimizing system-side equipment output and user-side energy consumption,the system achieves more efficient production and economic energy use,maximizing the profits of all participants.
