A Shareholding-based Energy Sharing Transaction Model for Energy Market Among Peer-to-peer Prosumers|基于股权分配的能源市场 P2P 能量共享交易模型

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.
