Abstract: In the future energy society, the value of hydrogen energy will be realized in the conversion of various types of energy sources, particularly as the key link in the power system. To this end, a new energy system capacity planning method based on different hydrogen load levels is proposed to promote the application and development of renewable energy sources more efficiently such as wind and photovoltaic energy in the power grid. The method can maximize the economical benefits of the system while meeting the regional hydrogen energy demand. Under different hydrogen production modes, the optimal hydrogen production system scale can also be determined. In addition, the penalty costs of curtailing wind and solar power and hydrogen energy supply shortage are taken into consideration as well as the environmental benefits of the system. The results show that it is more reasonable and economical to adopt the mode of grid-integrated wind power and photovoltaic energy transactions for electricity in hydrogen production, which avoids the redundant configuration of large-capacity hydrogen production-storage equipment.
