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.
