考虑消纳责任权重和共享储能介入的多微网非对称纳什谈判

Multi-microgrid asymmetric Nash negotiation considering the inclusion of responsibility weights and shared energy storage

在“双碳”政策的影响下,清洁能源成为了国家提倡使用的能源类型,在可再生能源不断发展并投入使用的同时,其浪费问题引起了广泛的关注,因此,储能技术应运而生。在共享储能和微网联盟之间,利益的分配问题是各方共同关注的,在考虑了国家推出的责任消纳的基础上,针对微网与储能电站的利益问题,提出了一种基于非对称的纳什谈判模型。将此非线性问题转化成微网联盟效益最大化和利益分配分配两个子问题依次求解,采用交替乘子法(alternating direction method of multipliers,ADMM)对其进行分布式求解,并将提出的非对称纳什谈判与对称的纳什谈判进行比较。通过对合作谈判的前后对比分析,得出所提的考虑消纳责任权重和共享储能介入的非对称纳什谈判模型能在降低各主体的成本同时,还能促进可再生能源的消纳,有效解决能源浪费问题。

Under the influence of the“dual carbon”policy,clean energy has become the type of energy advocated by the country.With the continuous development and application of renewable energy,the waste of renewable energy has attracted extensive attention,and energy storage technology has emerged.Between shared energy storage and micro-grid alliance,the distribution of benefits is of common concern to all parties.Therefore,an asymmetric Nash negotiation model for the benefits of micro-grid and energy storage power station based on the consideration of the responsibility absorption introduced by the state is proposed.Then,the nonlinear problem is transformed into two sub-problems of benefit maximization and benefit allocation of the micro-grid alliance.The alternating direction method of multipliers is used for distributed solution.The asymmetric Nash negotiation proposed is compared with the symmetric Nash negotiation.Through the comparative analysis of cooperative negotiation before and after,it is concluded that the proposed asymmetric Nash negotiation model considering the weight of absorption responsibility and the involvement of shared energy storage can not only reduce the cost of each subject,but also promote the absorption of renewable energy and effectively solve the problem of energy waste.
