Techno-economic study of a PV-hydrogen-battery hybrid system for off-grid power supply: Impact of performances' ageing on optimal system sizing and competitiveness

Abstract:The Photovoltaic-assisted Charging Station (PVCS) is regarded as one of the most promising charging facilities for future electric vehicle (EV) energy supplementation. In this paper, the operation mode and profitability of a commercialized PVCS are analyzed under the energy policy of China. In order to evaluate the long-term effectiveness of using the PVCS to provide guidance for the investors of the stations, a set of evaluation indexes is introduced, including the quality of service, the environmental and economic benefits, and the impacts on the grid. Furthermore, an easily-achieved charging strategy which considers the quality of service and the self-consumption of PV energy is proposed. Finally, an effectiveness evaluation for different operational scenarios of the PVCS is completed, based on the actual statistical data. The simulation and evaluation results indicate that the PVCS has the potential to produce satisfactory environmental/economic benefits and to reduce the impacts and dependence of an EV's charging load on the grid.

“…It is important to note that factors such as high emissions from diesel usage, possible future increased cost of diesel prices, and unreliability suggested by the service outages (e.g., due to poor supply of fuel or fuel theft) are some of the limitations that prevent the hybrid PV-diesel system to be favorably deployed for powering off-grid BS sites [41][42][43]. Figure 3 shows a typical set-up of the hybrid PV-diesel systems where the power is primarily supplied by the PV system and the diesel generator acts as a complementary power supply system to overcome the intermittency of solar energy.…”

“…In hybrid storage systems in which both batteries and hydrogen systems are used, the overall cost of the system, depending on the nature of the applications, can be cheaper [41,73] or more expensive [39,50] than using either of the systems alone. Based on a techno-economic study by Bezmalinovic et al [39], the levelized cost of electricity with and without a hybrid energy storage system (i.e., PV-hydrogenbattery and PV-battery systems, respectively) was found to be $0.70/kWh and $0.72/kWh, respectively.…”

Abstract:The telecommunication sector plays a significant role in shaping the global economy and the way people share information and knowledge. At present, the telecommunication sector is liable for its energy consumption and the amount of emissions it emits in the environment. In the context of off-grid telecommunication applications, offgrid base stations (BSs) are commonly used due to their ability to provide radio coverage over a wide geographic area. However, in the past, the off-grid BSs usually relied on emission-intensive power supply solutions such as diesel generators. In this review paper, various types of solutions (including, in particular, the sustainable solutions) for powering BSs are discussed. The key aspects in designing an ideal power supply solution are reviewed, and these mainly include the pre-feasibility study and the thermal management of BSs, which comprise heating and cooling of the BS shelter/cabinets and BS electronic equipment and power supply components. The sizing and optimization approaches used to design the BSs' power supply systems as well as the operational and control strategies adopted to manage the power supply systems are also reviewed in this paper.
