Energy Cooperation in Cellular Networks With Renewable Powered Base Stations
Source: National University of Singapore
In this paper, the authors propose a model for energy cooperation between cellular Base Stations (BSs) with individual renewable energy sources, limited energy storages and connected by resistive power lines for energy sharing. When the renewable energy profile and energy demand profile at all BSs are deterministic or known ahead of time, they show that the optimal energy cooperation policy for the BSs can be found by solving a linear program. They show the benefits of energy cooperation in this regime. When the renewable energy and demand profiles are stochastic and only causally known at the BSs, they propose an online energy cooperation algorithm and show the optimality properties of this algorithm under certain conditions.
