Optimizing Green Energy Utilization for Mobile Networks with Hybrid Energy Supplies

This chapter presents green energy optimization (GEO) schemes, which optimize energy utilization in cellular networks with hybrid energy supplies. The GEO scheme decomposes the problem into two sub‐problems: the multi‐stage energy allocation problem and the multi‐BSs energy balancing problem. The chapter proposes algorithms to solve these sub‐problems, and hence solve the green energy optimization problem. It introduces and investigates the green energy provisioning (GEP) problem, which aims to minimize the CAPEX of deploying green energy systems in BSs while satisfying the QoS requirements of cellular networks. The GEP problem is decomposed into the weighted energy minimization problem and the green energy system sizing problem. The chapter proposes a green energy provisioning solution consisting of a provision‐cost aware traffic load balancing algorithm and a binary energy system sizing algorithm to solve the sub‐problems and hence solve the GEP problem.
