摘要(Abstract):
为满足共享储能中储能用户的互补性和替代性需求、解决常规单向拍卖中可能存在的垄断竞争问题,提出了基于组合双向拍卖的共享储能机制。在该机制中,储能运营商和储能用户在拍卖商的组织下进行组合双向拍卖。拍卖包含四个阶段:投标、竞胜标决定问题、资源匹配与定价、资金结算。相较于现有拍卖机制,该机制支持"与"投标,使得买家的互补性需求得以准确而简洁地表达。在竞胜标决定问题方面,建立了以社会福利最大化为目标的混合整数非线性规划模型。进一步,将该模型等价转化为混合整数线性规划模型,大幅降低了计算时间复杂度。在定价方面,提出了在买卖双方之间均分社会福利的定价机制,打破了传统单向拍卖的垄断弊端。最后,通过算例验证了所提机制的有效性。
