摘要：
With the rapid development of mobile communication technology, the coverage area of mobile communication base stations is becoming more and more wide. And the construction of 5G base stations shows a trend of large-scale outbreak. The backup energy storage inside the base station is in an idle state for a long time, and the huge regulation capacity is in a “sleeping state”. It cannot participate in the power system operation and the system faces with the imbalance between supply and demand caused by the fluctuation of renewable energy resources. Firstly, this paper evaluates the regulatory potential of energy storage resources by power supply reliability indices and constructs a model of base station energy storage (BSES) in the condition of ensuring the backup demand of base station operation. Secondly, a dynamic aggregation method of the BSES is proposed. A virtual power plant (VPP) with BSES is constructed. Combined with model predictive control (MPC), the two-stage economic optimal dispatch for day-ahead declaration and intra-day rolling correction is designed. The simulation results show that the combination of time-domain rolling and real-time state feedback correction can realize the full accomodation of renewable energy resources on the basis of fully ensuring the power supply reliability of the base station. At the same time, the influence of the dispatchable capacity of BSES on the economy of VPP is quantified. Compared with 95% constant reserve capacity, the dynamic backup capacity model improves the economy of VPP by 4%. © 2022 Automation of Electric Power Systems Press. All rights reserved.
