Capacity Optimization Configuration of Battery, Thermal and Hydrogen Multi-Energy Complementary System Considering Battery Life

Energy storage technology with spatiotemporal transfer capability can provide an effective way to solve the potential problems in the high-proportion renewable energy power system. Due to the limitations of technical principles and key materials, the single energy storage technology is unable to simultaneously meet the needs of the system for the energy-type and power-type energy storage. Therefore, this paper proposed a capacity optimization configuration model for the multi-energy complementary system. Based on the regulation characteristics of the sodium-ion battery, hydrogen and thermal energy storage, the model not only considers the coupling of the electricity, hydrogen and thermal, but the service life of the battery and the interactions between the system and the market has been taken into consideration too. The multi-energy complementary system combines the advantages of different energy technologies which can suppress unbalanced power and improve the power quality on different time scales effectively.
