Multi-objective planning for integrated energy systems considering both energy quality and renewable energy

Traditional integrated energy system planning studies focus only on the quantity of energy while ignoring the differences in the quality of different energies, which cannot fully reflect the value of energy and has limitations.

Description
Summary:Traditional integrated energy system planning studies focus only on the quantity of energy while ignoring the differences in the quality of different energies, which cannot fully reflect the value of energy and has limitations. Based on the concept of the high-exergy integrated energy system and exergy flow model, this paper studies the planning model of the distributed wind turbine, hydrogen blended natural gas, and energy conversion equipment expansion in the integrated energy system from the perspective of energy quality improvement. The planning results show that distributed wind turbines can reduce the exergy loss of the power system. Consideration of the exergy efficiency and exergy loss index in the planning is conducive to promoting the consumption of renewable energy. Hydrogen blended natural gas can reduce the carbon emission costs of natural gas systems, but it can reduce the energy quality of natural gas systems. The overall exergy efficiency of an integrated energy system is improved, but the energy quality of its parts is not necessarily improved.
