Abstract:The energy consumption of cellular networks has become increasingly important to cellular network operators, due to the significant economic and ecological influence of these networks in the future. The development of alternative energy technologies has resulted in the consideration of a solar powered base station (BS) as a long-term solution for the mobile cellular network industry, to reduce the operational expenditures and CO 2 footprints of cellular networks. This study addresses the deployment and operational issues of a solar powered universal mobile telecommunications system (UMTS; a third generation mobile cellular system) BS (i.e., Node B) that is currently deployed (i.e., UMTS Node B 2/2/2 and UMTS Node B 4/4/4). In addition, this study employs a hybrid optimization model for an electric renewable software simulator developed by the American National Renewable Energy Laboratory. Four key aspects are discussed in this study: optimal solar system architecture, energy production, the cash flow of the solar powered UMTS Node B project, and the economic feasibility of a solar powered system compared with traditional sources. Simulation results show that the proposed solution ensures 100% energy autonomy and long-term energy balance for the UMTS Node B, with cost effectiveness.

The energy storage devices are necessary to the stand alone PV generation system.Lead acid battery which performance is specially designed is suitable for PV generation application. The battery charging and discharging control with the max power of PV array is the key point to increase efficiency of the generation system. In this paper, the new system configuration with parallel battery charger is designed. The conversion steps are decreased and system conversion efficiency is increased. The two module MPPT coordinate control is designed to increase PV utilizing efficiency. According to the different battery characteristics, the battery management is optimized for better performance and longer life time. The performance and total efficiency of PV generating system can be improved for stand-alone application. The experimental results of the prototype verify the effectiveness of proposed protocol and strategy.

Abstract. The paper is focused on the modelling of an inductor to exploit its non-linear behaviour in the roll-off region when it is employed in a DC/DC converter. The model is set up on the basis of experimental data measured in operating conditions, which are fitted to a polynomial curve describing the inductance variations. The analysis of the buck converter, performed by including the proposed model, is validated by experimental tests.
