基于股权分配的能源市场P2P能量共享交易模型

A Shareholding-based Energy Sharing Transaction Model for Energy Market Among Peer-to-peer Prosumers

全球能源格局正在发生深刻变化,能源结构正朝着多元化、清洁化和低碳化的方向发展。从能量交易的角度来看,全球能源格局的变化也促使跨区域、跨行业之间在需求侧进行点对点(peer-to-peer,P2P)的能量交易,以消纳高比例可再生能源。传统的P2P市场主要为拥有独立的分布式能源发电和储能设备的单个用户之间的能量共享提供平台。然而,由于空间的限制,一些用户可能需要共享一组分布式能源和储能设备,即群体产消者。为了加强对能量生产与消费的管理,该文提出一个由股权交易和能量交易组成的P2P能量共享交易模型。在股权交易模式中,引入了股权制,以提高群体产消者在能量交易中的参与度。群体产消者中的用户可以通过购买股权来获得发电资格,并且从中获得股权收益。与此同时,为实现分布式能源的高效率利用,用户可依据自身需求进行股权的自由买卖,从而实现发电容量的转让。在能量交易模型中,该文构建了自组织交易和区域市场交易结合的双层交易模型,实现产消者之间的能量共享。最后以IEEE 33节点系统为例验证了该方法的有效性。结果表明,提出的交易模型能够充分调动用户参与能量管理与共享的积极性,股权模型能显著提升可再生能源利用率,为区域能量共享提供了新的思路。

The global energy map is undergoing profound changes and the energy structure is developing towards pluralistic,clean and low carbon.From the perspective of energy trading,the change of global energy map also promotes trans-regional and cross-industry to carry out peer-to-peer(P2P)energy trading on the demand side to consume high proportion of renewable energy.The traditional P2P market provides a platform for energy sharing among single-prosumers with independent distributed energy resources and storage devices.However,due to the space constraints,some individuals may only share a set of distributed energy resources and storage devices,namely group-prosumers.In order to strengthen the management of energy production and consumption,a P2P energy sharing transaction model for energy market was proposed,consisting of shareholding trading and energy trading.In the shareholding trading model,a shareholding system was introduced to improve the active participation of members of group-prosumers in energy sharing.The members can purchase the shareholdings to dominate the generation qualification and obtain the shareholding returns.Meanwhile,in order to achieve high efficiency use of the distributed energy resources,the individuals can buy or sell the shareholdings freely according to their own needs to realize the transfer of generation capacity.In the energy trading model,this paper constructed a double-deck trading model which combines self-organization trading and local microgrid market to realize the energy sharing among the prosumers.Finally,the IEEE 33-bus system was employed to verify the effectiveness of the method.The results show that the proposed trading model can fully arouse the enthusiasm of the individuals to participate in energy management and sharing and the shareholding model can significantly improve the utilization rate of renewable energy,which provides a new idea for regional energy sharing.
