    Abstract
  • For the dilemma of modeling & optimizing of DES/CCHP due to the absents of variable-interrelation among sub-systems, a logic modeling/optimizing energy flux chart of DES/CCHP is advanced, which including 9 sub-systems, that are power-system, DCS, DWS, hot water, renewable generating, SMG, gas/LNG, hydrogen, and industrial waste heat.It was pointed out that the topology structure & parameters inside a sub-systems are may be described and optimized, but not existed among different sub-systems.Therefore, a Decomposing/Coordinating strategy has been adapted and electricity is the main coordinating variable.Two main strategies are advanced: (1)Modeling & optimization was realized via optimizing and iterating among multi-operation-subsystem modeling with design modeling; (2)The direct targets of optimization was the economic benefit, high energy-efficiency target comes from sub-system decision according to the principle of "Use energy scientifically" , while low carbon target depends upon energy efficiency and choosing of primal energy.Above method has been applied in design & construction of many natural gas DES/CCHP projects.Thus, it has important scientific meaning and practical prospect.
