Title: Research on Coordination Mechanism of regional electricity hydrogen coupling comprehensive energy flexibility and optimization of cross domain system for deep decarbonization

Abstract:

Under the background of low-carbon development, the trend of re electrification and low-carbon development of urban energy consumption is obvious. With the development of new industries such as integrated circuits and new infrastructure such as 5g and data centers, China will promote a new round of rapid growth of regional energy. As a major city receiving external power, Shanghai will face large-scale distributed energy grid connection, and the proportion of superimposed terminal power consumption will grow rapidly. The safety and reliability of urban distribution network will face great challenges. The "electricity hydrogen" coupling system is considered to be an important component of future energy that can break through the limitations of renewable energy development and achieve the power and electricity balance of multi-level power grids. It is an important way to realize the green and low-carbon transformation of terminal energy, and expand the scope and depth of power substitution. This paper aims to meet the needs of deep power substitution and decarbonization on the user side, excavate the flexibility of electric hydrogen coupling in new power systems, adjust the margin, and expand typical electric hydrogen coupling scenarios such as "traffic power, industrial heating, building heating" to achieve deep decarbonization in the process of terminal energy re electrification. This paper puts forward the evolution path of regional electric hydrogen coupling, and scientifically arranges sufficient electric hydrogen two-way interactive conversion devices in the space-time of the power network, so as to improve the stability of the green distribution network system. This research work will provide a decision-making theoretical reference for actively supporting the new power system and building a low-carbon, green, hydrogen electricity coupled deep decarbonization energy supply system.
