Research on Modeling Method of P2H for Power Grid Dispatch

Hydrogen energy, as a new zero carbon energy source, has the characteristics of environmental safety, high energy density, high conversion efficiency, abundant reserves, and wide applications. China is a major hydrogen producing country, and converting new energy into hydrogen energy will also be an important way for China's future consumption of new energy. Faced with the small capacity and large quantity of single tank hydrogen production, which leads to numerous integer decision variables, this paper proposes three modeling methods: fine modeling, simple aggregation modeling, and algorithm aggregation modeling. Through simulation analysis, it is found that the simple aggregation model considering two states can meet the power grid scheduling needs at the large grid level.
