This study develops a mathematical model and investigates an optimization approach for optimal sizing and deployment of solar photovoltaic (PV), battery bank storage and a diesel generator for grid connected telecommunication base station.
Due to the fact that base stations (BSs) are the main energy consumers in cellular access networks, this paper overviews the issue of BS management to achieve energy efficiency (load proportionality) in cellular access networks.
Abstract: This paper presents the design considerations and optimization of an energy management system (EMS) tailored for telecommunication base stations (BS) powered by photovoltaic (PV) systems and battery energy storage systems (BESS).
An improved base station power system model is proposed in this paper, which takes into consideration the behavior of converters. And through this, a multi-faceted assessment criterion that considers both economic and ecological factors is established.
To this end, an algorithm was implemented that aims at a good and close management of energy transit to ensure a permanent supply of energy while taking into account the economic aspect of the system.Can a base station power system model be improved?An improved base station power system model is proposed in this paper, which takes into consideration the behavior of converters. And through this, a multi-faceted assessment criterion that considers both economic and ecological factors is established.
Can a base station power system be optimized according to local conditions?The optimization of PV and ESS setup according to local conditions has a direct impact on the economic and ecological benefits of the base station power system. An improved base station power system model is proposed in this paper, which takes into consideration the behavior of converters.
How to optimize base station operating modes?The method for optimizing base station operating modes does not require any changes to the system’s original power supply structure. The purpose of energy conservation is achieved by adjusting the operating status of base stations [5, 6] and even shutting down some base stations according to actual user needs [7, 8, 9].
Does converter behavior affect base station power supply systems?The influence of converter behavior in base station power supply systems is considered from economic and ecological perspectives in this paper, and an optimal capacity planning of PV and ESS is established. Comparative analyses were conducted for three different PV access schemes and two different climate conditions.
Does loss of power converters affect the optimization of base station PV and ESS?The main conclusions are as follows: The loss of power converters significantly affects the optimization of base station PV and ESS. Calculating with a fixed efficiency cannot accurately reflect the actual situation. The proposed evaluation method achieves a balance in LCC, initial investment, return on investment, and carbon emissions.
How ESS is connected to a base station?Scheme 1: The classic scheme in which the base stations are only powered by grid electricity. Scheme 2: The PV modules are connected in series to obtain higher voltage and are connected to the AC bus of the base station through an inverter with MPPT function. ESS is connected to the 48 V DC bus through bidirectional DC/DC convert
