Distributed PV sharing service mechanism for park based on the concept of sharing economy

The sharing economy is a new economic mode that can effectively promote the optimal allocation and utilization of the existing resources. Its integration with the distributed energy domain has a great significance in enhancing the utilization rate of equipment and reducing the cost of energy consumption of users. Therefore, this paper presents a distributed photovoltaic (PV) sharing service mechanism for the distributed PV existing resources of users in the park. Firstly, the architecture of the distributed PV sharing service mechanism is established, and the business process of the service mechanism is designed. Then, a model of distributed PV sharing user group is established, which can effectively analyze the sharing power, the net energy cost, and the purchased and sold power of the sharing user group. After that, a distributed PV sharing benefit model, a benefit allocation model based on a heuristic method, and a cost settlement model are established. Afterwards, the coupling relationship between the sharing benefit and the tariff profit interval and the amount of sharing electricity is discussed, and the heuristic benefit allocation method is compared and interpreted from the perspective of the tariff. Finally, it is verified through case study that the presented mechanism can effectively promote the localized sharing of distributed PV energy and reduce the cost of energy consumption of users.
