Abstract

To adapt to the green and low-carbon energy transition, this paper proposes a low-carbon optimal scheduling method for a multi-energy complementary virtual power plant （VPP） considering hydrogen energy cycle and electrolytic molten carbonate （EMC） carbon capture technology. First, a hydrogen cycle system including the electrolyzer, methane reactor, hydrogen-blended unit, hydrogen fuel cell （HFC）, and hydrogen storage tank is constructed. This system covers multiple stages of hydrogen production, storage, and utilization to fully explore the interconnected potential of hydrogen energy with electrical and thermal energy. Second, EMC technology is introduced to establish an EMC carbon capture power plant that incorporates the gas turbine, an organic Rankine cycle （ORC） low-temperature waste heat power generation unit, and waste heat boiler. Finally, considering the synergy between virtual and fixed energy storage, such as electric vehicles, alternative response loads, and air conditioning loads, as well as the differences in response performances among various storage types, a day-ahead and real-time optimal scheduling model for VPP is proposed to improve the operational flexibility. Case studies show that the proposed method can effectively facilitate renewable energy integration, reduce operating costs and carbon emissions, and enhance overall energy utilization efficiency.
