Optimal Electricity Dispatch for Base Stations with Battery Storage System: A Case Study in Shanghai

With the development of newer communication technology, considering the higher electricity consumption and denser physical distribution, the base stations become important commercial load of the power system. Therefore, the electricity consumption analysis and optimization approaches of base stations become meaningful. Referring to the pilot configuration of battery storage system with large capacity in the base stations, the battery storage system can be utilized to schedule the base station’s electricity consumption to minimize total operational cost of base stations. In this paper, the optimal electricity dispatch strategy for base stations with battery storage system is proposed. Firstly, on basis of the linear relationship between the communication load rate and the base station’s electric load, the electric load prediction model of base station considering dynamic communication load rate is formulated. Then, considering the time of use electricity price scenario, the optimal electricity dispatch model for base stations with battery storage system is developed to minimize the total operation cost of the base station. Finally, case studies demonstrate the validity and effectiveness of the proposed methodology.
