Abstract
At the present stage of electric power industry development, special attention is being paid to the development and research of new efficient energy sources. The use of hydrogen fuel cells is promising for remote autonomous power supply systems. The authors of the paper have developed the structure and determined the optimal composition of a hybrid generation system based on hydrogen fuel cells and battery storage and have conducted studies of its operating modes and for remote consumers’ power supply efficiency. A simulation of the electromagnetic processes was carried out to check the operability of the proposed hybrid generation system structure. The simulation results confirmed the operability of the structure under consideration, the calculation of its parameters reliability and the high quality of the output voltage. The electricity cost of a hybrid generation system was estimated according to the LCOE (levelized cost of energy) indicator, its value being 1.17 USD/kWh. The factors influencing the electricity cost of a hydrogen generation system have been determined and ways for reducing its cost identified.
Highlights
The global trends in the modern electric power industry are decarbonization and decentralization aimed at improving the environmental friendliness, reliability and quality of power supply to consumers [1]
This study shows that Fuel cells (FC) can be a useful alternative to PV
The important advantages of PEMFCs are their high power density, a short start and stop time, a high load change rate within a wide range, ease of operation and the ability to work in a wide range of ambient temperatures [21]
Summary
The global trends in the modern electric power industry are decarbonization and decentralization aimed at improving the environmental friendliness, reliability and quality of power supply to consumers [1]. The paper is devoted to the development of a hydrogen fuel cell generation system (HFCGS) for power supply to remote low-power consumers (up to 3 kW). Hydrogen fuel cells eliminate these problems, and they are promising power sources for remote low-power consumers. The concept and prototype of a hybrid system that integrates PV, battery storage and hydrogen fuel cells for power supply of remote telecommunications is described in [9]. This system powers a 12-V load with a power of just under 10 W during the day. The study goal is to develop the structure and select the optimal composition of an HFCGS that provides a minimum number of converters and the size of the system and to study its operation modes and the efficiency of its use as a power supply for remote consumers
