Collaborative Optimization of Base Station Backup Battery Considering Communication Load

As the penetration rate of renewable energy in the power system grows, the need for the power system to find new flexible resources to maintain its stability increases. At the same time, abundance of base stations (BSs) are constructed along with the rapid development of Information and Communications Technology (ICT). Batteries are installed as back-up power for the BSs but are rarely used in light of the high stability of power grid. In this paper, we proposed a method to use the back-up batteries as demand response resources while ensuring the safe operation of BSs.
