摘要：
The mature technology and strong adjustment ability of the hydrogen gas turbine is able to transform the electricity-hydrogen energy storage-electricity complementary system into the electricity-hydrogen energy storage-electricity/heat complementary system, thus broadening the routes of the multi-energy complementation. Therefore, this paper establishes a hydrogen energy storage unit (HESU) based on the hydrogen gas turbine, and an electricity-heat-hydrogen complementary system (EHHCS) is formed. The optimal operation mechanism of the system is analyzed and the modeling is completed from three inspects, including the hydrogen production by water electrolysis of renewable energy, the hydrogen energy storage technology, and the hydrogen gas turbine technology. Considering the multi-energy conversion efficiency of the HESU, and taking the purpose of minimizing the operation costs and promoting the wind power accommodation, an optimal dispatching model of the grid with the EHHCS is established, whose effectiveness is verified with simulation. Results show that adopting the hydrogen gas turbine as the generating part of the HESU is a feasible scheme. The electric power efficiency of the HESU is about 75%, which reaches the energy efficiency level of the pumped storage, having a practical value. The results will provide a reference for the optimal dispatching of the multi-energy complementary system with energy storage units. © 2022 Power System Technology Press. All rights reserved.
