摘　　要：将光伏(PV)主体与氢储能(HES)主体结合,形成PV-HES联合系统,是促进可再生能源就地消纳,实现能源低碳转型的有效措施。针对光伏出力随机干扰及主体互异等问题,提出PV-HES的分散协同调度模型。首先,基于Nash-Harsanyi讨价还价理论建立PV-HES的多主体合作运行模型,并将其等效转换为电能交易量确定子问题和电能交易成本确定子问题;然后,为了保护各主体隐私,运用改进的交替方向乘子法对上述两个子问题进行分布式求解;最后,在一个典型的PV-HES联合系统中进行算例仿真,以验证所提分散协同调度模型以及分布式求解算法的有效性。仿真结果表明,氢储能主体的运营成本分别降低了11.67%和10.48%,光伏运营商的收益提高了15.72%。此外,通过对交替方向乘子法的改进也提高了系统的求解效率。Integrating photovoltaic(PV)and hydrogen energy storage(HES)into a PV-HES joint system proves to be an effective strategy in boosting local consumption of renewable energy and facilitating the low-carbon transformation of energy.The system's internal photovoltaic output and load exhibit considerable randomness,influencing the system's stable operation.Additionally,PV and HES,being typically associated with different stakeholders,each prioritize maximizing their own interests,which limits the effective operation of the PV-HES joint system.Current research often overlooks the bargaining power of diverse entities within the system,failing to fully portray each entity's actual contributions in cooperative efforts amidst uncertainties.In response to these problems,the relationships between entities in the PV-HES combined system should be coordinated and multiple uncertainties should be considered to ensure the stable operation of the PV-HES combined system.Initially,utilizing Nash-Harsanyi bargaining game theory,the study formulates a multi-agent cooperative operational model for PV-HES.This model equivalently addresses the determination of power transaction volume and power transaction cost as distinct subproblems.The Nash-Harsanyi bargaining game extends the Nash bargaining game into an asymmetric game model.This model accounts for participants'bargaining power and their contributions in cooperative efforts,ensuring a fair distribution of benefits.Secondly,stochastic optimal operating models for PV and HES systems were created using probabilistic scenarios,considering uncertainties in both energy supply and load aspects.These models aim to minimize cooperative operational costs.Thirdly,to safeguard the privacy of each participant,the improvement of alternating direction multiplier method(ADMM)is employed to address the aforementioned two subproblems.This method utilizes a two-stage dynamic step size correction approach.To validate the efficacy of the proposed decentralized collaborative scheduling model and distribu
