摘要
针对未充分挖掘具有源荷双重特性的电动汽车集群调度潜力以辅助电力系统低碳运行的问题,提出了计及电动汽车的综合能源系统内多主体协同低碳经济调度策略。首先,考虑综合能源系统内多主体的电能交易构建了风电主体优化运行模型、计及碳捕集与电转气系统综合灵活运行的电-热耦合系统优化运行模型以及电动汽车主体优化运行模型;其次,基于纳什谈判理论建立了综合能源系统内多主体合作运行模型,将其分解为多主体联盟效益最大化子问题和电能交易支付谈判子问题,并采用交替方向乘子法对上述两个子问题进行了分布式求解以保护各主体的隐私;最后,通过算例仿真验证了所提策略能够充分挖掘碳捕集-电转气系统和电动汽车集群支撑风电消纳实现综合能源系统碳减排的潜力,提高各主体的运行效益以及合作联盟的整体效益,有效实现综合能源系统内各主体协同互济,促进新能源消纳、提升系统低碳性和经济性。
Aiming at the problem that the potential of electric vehicle cluster scheduling with source-load characteristics is not fully explored to assist low-carbon operation of the power system,this paper proposes a multi-agent collaborative low-carbon economic dispatch strategy in the integrated energy system considering electric vehicles.Firstly,considering the multi-agent electricity trading in the integrated energy system,the optimal operation models of the wind power,the electricity-heat system considering the comprehensively flexible operation of carbon capture and power-to-gas(P2G)systems,and electric vehicles are constructed.Secondly,a multi-agent cooperative operation model in the integrated energy system is established based on the Nash bargaining theory,which is decomposed into a multi-agent alliance benefit maximization sub-problem and the electricity trading payment bargaining sub-problem.The alternating direction method of multipliers is adopted to solve the above two sub-problems by the distributed algorithm and protect the privacy of each agent.Finally,the case simulation results show that the proposed strategy can fully realize the potential of the carbon-capture-P2G system and electric vehicle cluster of supporting wind power accommodation to achieve carbon emission reduction in the integrated energy system,improve the operation efficiency of each agent and the overall efficiency of cooperation alliance,and effectively realize the synergic mutual aid of each agent in the integrated energy system while promoting renewable energy accommodation and improving the low-carbon performance and economy of the integrated energy system.
