Abstract: The 5th generation mobile networks (5G) is in the ascendant. The 5G development needs to deploy millions of 5G base stations, which will become considerable potential flexibility resources for power systems. Meanwhile, dispatching 5G base stations to participate in demand response can significantly reduce the 5G-power consumption cost. Therefore, 5G base station dispatch can achieve a win-win situation between communication systems and power systems. This paper introduced the essential equipment and power consumption characteristics of 5G base stations and investigated their demand response potential. Then, the key technologies for 5G base station to participate in demand response was analyzed. Further, the application scenarios to dispatch 5G base stations as demand-side resources were considered. Finally, potential business models were discussed.
