摘　　要：随着需求侧资源开发力度持续加大和电力市场机制不断完善,需求侧分散的灵活性资源将在电力调度与交易中扮演更重要的角色。虚拟电厂的建设为需求侧资源管理和利用提供了新思路,同时,电能共享因其能够促进区域电力平衡和提升电力系统灵活性而备受关注。为此,文中对基于虚拟电厂的电能共享交易机制进行了研究。首先,提出了共享型虚拟电厂概念,并建立其与新能源场站的电能共享框架;其次,考虑新能源出力不确定性,基于最小-最大后悔值法建立共享联盟风险调度模型;然后,基于一致性理论推导出共享电能价格机制;最后,基于改进的IEEE 33节点系统进行算例分析。结果表明,所提调度方法与交易机制能够提高用户侧资源利用效率、促进新能源消纳与电网区域供需平衡。As the development of demand-side resources continues to increase and the electricity market mechanism is being improved,the decentralized flexibility resources on the demand side will play a more important role in the power dispatch and trading.The construction of virtual power plants provides a new idea for the demand-side resource management and utilization,while the power sharing has attracted much attention for its ability to promote regional power balance and enhance power system flexibility.To this end,the power sharing trading mechanism based on virtual power plant is studied.Firstly,the concept of sharing-based virtual power plant is proposed and the framework of power sharing with renewable energy stations is established.Secondly,the risk scheduling model of sharing alliance based on the minimum-maximum regret method considering the uncertainty of the renewable energy output is established.Then,the price mechanism of shared power based on the consistency theory is derived.Finally,case analysis is conducted based on the modified IEEE 33-bus system.Results demonstrate that the proposed scheduling method and trading mechanism can improve the utilization efficiency of user-side resources,promote the renewable energy accommodation and balance the regional supply and demand of the power grid.
