“…However, because of their energy leakage between 1% and 5% per hour, and their low energy densities, they are not useful for long-term operation of power systems [16]. Hydrogen can be a good choice due to its high energy density, low energy loss, mature technology, on-site provision capability, and compactness [17][18][19][20]. One of the most promising ways of producing hydrogen is through the electrolysis of water using an electrolyzer.…”

The rising demand for high-density power storage systems such as hydrogen, combined with renewable power production systems, has led to the design of optimal power production and storage systems. In this study, a wind and photovoltaic (PV) hybrid electrolyzer system, which maximizes the hydrogen production for a diurnal operation of the system, is designed and simulated. The operation of the system is optimized using imperialist competitive algorithm (ICA). The objective of this optimization is to combine the PV array and wind turbine (WT) in a way that, for minimized average excess power generation, maximum hydrogen would be produced. Actual meteorological data of Miami is used for simulations. A framework of the advanced alkaline electrolyzer with the detailed electrochemical model is used. This optimal system comprises a PV module with a power of 7.9 kW and a WT module with a power of 11 kW. The rate of hydrogen production is 0.0192 mol/s; an average Faraday efficiency of 86.9 percent. The electrolyzer works with 53.7 percent of its nominal power. The availability of the wind for longer periods of time reflects the greater contribution of WT in comparison with PV towards the overall throughput of the system.

“…However, in an experimental study made by Petrollese et al [86], by expanding the hydrogen-based storage capacity compared to adding batteries in renewable energy power supply systems, a savings of about 10% was achieved in annual O&M costs and a 6% decrease of energy losses was expected. However, either way, hybridization of the storage system can enhance the reliability of the system that is essential in BS sites in which 100% reliability and uninterrupted operation are required [41,50,[87][88][89][90]. Figure 7 shows the schematic diagram of a hybrid energy storage system used in a typical BS site.…”

“…Castañeda et al [87] proposed three control strategies, which are modeled using Simulink Design Optimization (SDO) of MATLAB, for managing the energy flow of a hybrid PV-hydrogen-battery system. Control strategy 1 uses the simplest control scheme to maintain the battery's SOC at an optimum level and the charging and discharging of the battery are used as control variables of the system.…”

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.

“…The total use of renewable energy sources in the worldwide is 6.4% as on 2011 [1] Recently, hybrid system using renewable energy sources is used to fulfill the vast energy demand in rural and remote areas such as radio telecommunications and satellite earth stations. Hybrid energy systems are more attractive and chosen as alternative energy sources where the power supply needed area is far away from the non renewable energy sources [2][3][4]. Among them, some of the resources are highly stochastic and site-specific [5].…”

This paper presents the performance of a hybrid solar PV/ Fuel Cell/ FC system with a PMDC motor load. The hybrid system supplies power to the DC motor during day and night. In order to obtain continuous supply to the load, a control strategy is implemented in the system. By using this control strategy, the solar PV and the fuel cell supply the voltage to the load by getting constant supply from the DC link during day and night. The DC-DC interleaved soft switching boost converter (ISSBC) with Incremental conductance maximum power point tracking technique (INC MPPT) is used to maintain constant DC link voltage. When the power deficit happens in the solar PV, the hydrogen stored in the tank is used by the fuel cell stack and supplies power to the load. The entire system is modeled and the performance of the hybrid system is analyzed in MATLAB/Simulink environment.
