Economic and Energy Efficient Design Method for a Green Wireless Telecommunication Power System


This paper presents an energy efficient design and an operational method for a Li-ion battery powered wireless telecommunication power system. Wireless telecommunication service providers have strived for reducing the Operating Expenditure (OPEX) of their Base Stations (BTS) because an urban BTS consumes more power as the data uses of mobile subscribers increase in these days. Thus, in order to reduce the OPEX, mobile service providers have studied for a green BTS which uses less electricity from the main power grid for its normal operation with renewable or alternative energy sources. Because these energy sources require high Capital Expenditure (CAPEX), a green telecommunication power site without a proper design and operational plan may increase the Total Cost of Ownership (TCO) that includes OPEX and CAPEX. Although such capital investment can be retrieved over time, few wireless service providers seem to have focused on the TCO reduction of a green BTS for its planning and designing stage. Therefore, this paper proposes an energy efficient design and an operational method for a green telecommunication power system which uses a Li-ion battery to reduce its TCO. To achieve this TCO reduction, the proposed paper considered various aspects including BTS energy profile, electricity rate, battery health and lifetime, charging and discharging cycle for a battery in the wireless telecommunication power system.
