Integrated Energy System Optimal Operation in Coal District With Hydrogen Heavy Trucks

The coal industry contributes significantly to the social economy, but emission of greenhouse gases puts huge pressure on environment in process mining, transportation, and power generation. In integrated energy system (IES), current research about power-to-gas (P2G) technology mainly focuses injection hydrogen generated from renewable electrolyzed water into natural gas pipelines, which may cause embrittlement pipeline cannot be repaired. this paper, sufficient can produced through P2G coal-to-hydrogen (C2H) gasification, considering typical scenario district is rich energy. order transport mined destination, heavy trucks have a broad space for development, absorb time avoid potentially dangerous pipelines relatively expensive storage. An optimized scheduling model electric-gas IES proposed based second-order cone programming (SOCP). above, closed industrial loop (including production, truck transportation coal, systems) has been innovatively studied, consume coordinate multi-energy. Finally, an study case constructed by IEEE 30-node Belgium 24-node network was used analyze. results show that introducing production technology, daily operating costs are effectively reduced 7.7%. Under China’s carbon emissions trading system, 0.95 4.68% respectively, compared with electric vehicles diesel trucks. Europe’s stricter percentages cost reduction 2.56 9.12%, respectively. above technical verify feasibility, low carbon, effectiveness mechanism.
