Abstract: In allusion to the key scientific issue of economic multi-base station energy sharing mechanism and implementation method for 5G-integrated distribution network, firstly, a base station energy sharing system was built, a base station energy sharing capability model was proposed, an inter-base station energy sharing connection model and an energy purchase model between base stations and distribution network were established. Secondly, a low-cost base station energy sharing method based on one-to-many price-rising matching was proposed to solve the energy sharing conflict problem. Finally, the performance of the proposed algorithm was verified by simulation. The results of simulation show that compared with the one-sided matching based base station energy sharing algorithm and the base station optimal energy purchase algorithm, the proposed algorithm can reduce the energy purchase cost by 14.37% and 41.80%, and reduce the discarded amount of photovoltaic energy by 56.80% and 85.58%, respectively. The proposed algorithm can promote the cost reduction of base station and the local consumption of renewable energy, and contribute to the construction of 5G network and new power system.
