| Summary: | In order to select a more economical wind power consumption scheme for RIES （regional integrated energy system）， the electricity-gas multi-energy complementarity optimization models considering the reuse of waste heat from power to gas （P2G） reaction and the electric-thermal multi energy complementary optimization model of air source heat pump （ASHP） are established based on the principle of multi-energy complementarity. Taking account of the investment and maintenance cost of P2G and ASHP， the RIES multi-energy complementary economic dispatch model is established with the goal of minimizing the overall operating cost of the system. Constraints of energy supply and demand balance and various unit operation constraints are considered. The optimization software CPLEX is used to solve various models. The example calculation results show that the scheme considering the reuse of waste heat from P2G reaction can reduce the configuration capacity of P2G and increase the operation benefit of the system. On condition of the same consumption rate of wind power， the electric-thermal multi-energy complementary optimization model with ASHP is superior in economy and overall energy efficiency. |
