Adaptability Assessment of Hydrogen Energy Storage System Based on Proton Exchange Membrane Fuel Cell under the Scenarios of Peaking Shaving and Frequency Regulation

With China already committing to peak carbon dioxide emissions before 2030 and achieve carbon neutrality before 2060, the evolution of the power system to a high-proportion new energy power system will be accelerated. The randomness and volatility of wind and photovoltaic power generation have brought challenges to the safe and stable operation of the power grid. The power system will require large-scale energy storage as a flexible resource to participate in regulation to maintain the safe and stable operation of itself. As a clean, carbon-neutral, and multi-functional secondary energy carrier, hydrogen will play an important role in the flexibility adjustment of a high-proportion renewable energy power system. Therefore, it is of great significance to study the adaptability of hydrogen energy storage in power systems. This study compares the adjusting characteristics of hydrogen energy storage with other energy storage in terms of regulation technology characteristics. This study firstly introduces hydrogen energy storage system and its application scenarios in power grid, followed by proposing an adaptability assessment method, finally give results and suggestion based on the assessment for energy storage planning.
