英文摘要:

      As the construction of 5G base stations continues to spread, the issue of high energy consumption and high cost of base stations is a major concern. Through the configuration and optimal operation of photovoltaic（PV）and energy storage, and further participation in peak regulation auxiliary services, the economy of 5G base station energy use can be effectively improved, and the scale application of green energy in 5G base stations can be realized. Therefore, the economics of 5G base station PV and energy storage systems participating in peak regulation auxiliary services are studied. Firstly, an optimization goal model considering the participation of PV and energy storage systems in peak regulation auxiliary services is established according to the load characteristics of base stations and different peak regulation periods；Then, CPLEX optimization solver is used to solve the optimization model and obtain the optimal capacity and operation strategy of energy storage.Finally, the scenarios of energy storage independently participating in peak regulation and PV and storage jointly participating in peak regulation are constructed with different peaking modes are built and cases show that greatly affect the optimal configuration capacity of energy storage and the energy cost of 5G base stations. A reference for the optimal operation of 5G smart base station optical storage system participating in peak regulation auxiliary services can be provided.
