Operation Strategy Study of Wind-Solar-Hydrogen-Chemical Integration System

Hydrogen energy is clean, low-carbon and efficient secondary energy source. Hydrogen production through new energy is an important approach to constructing clean energy network. This work takes synergistic control of new energy-hydrogen-energy storage-chemical integration as an entry point, and proposes a system scheduling method that matches the fluctuating new energy considering the grid access, source-load coordination, and new energy consumption. The system reduces the impact of new energy generation fluctuations on downstream loads by scheduling energy storage resources, so that the downstream chemical loads maintain smooth operation in general. Meanwhile, the operating characteristics of the system under different scenarios such as off-grid/grid-connected are analysed and compared, providing a theoretical basis for carrying out large-scale green hydrogen production projects.
