Optimal Configuration Planning of Combined Cooling Heating and Power - Heat Pump Coupled Energy Supply in Park

Integrated energy systems are regarded as effective solutions for building low-carbon parks. Under principles of multi-energy complementarity and cascade energy utilization, Combined Cooling Heating and Power (CCHP) - heat pump coupled energy supply system is adopted with advantages of high energy efficiency and enhanced reliability. The optimal configuration planning is the key to design this complicated system. First, the methods and algorithms for the installed capacity matching optimization of CCHP and heat pump are developed. Then, a case study is performed with the methodology proposed. Based on the load distribution in the park, and with consideration of the annual full load equivalent energy supply hours the CCHP - heat pump coupled energy system could reach, the optimal installed capacity portfolio of CCHP, water source heat pump (WSHP) and air source heat pump (ASHP) are determined by economic evaluations.
