Abstract:

In order to fully tap the potential of “source-load” coordinated peak shaving of the multi energy complementary energy system,an economic dispatch method of regional integrated energy system based on demand response and heat pump joint peak load shaving is proposed.On the source side,the gas heat pump is introduced and the energy supply is replaced by multi energy complementarity to give full play to the complementary characteristics of electric-gas energy,thus reducing the operation load of the peak air conditioning equipment.Considering the price-based demand response,the load side integrates the user’s power consumption satisfaction into the demand response model,and optimizes the power demand taking into account the user’s power consumption experience so as to realize the “peak shaving and valley filling” of power load.The model is established to minimize the system operation cost and solved by the optimization software CPLEX comprehensively considering the energy balance and demand response constraints,etc.The case study shows that the source-load coordinated peak load shaving can effectively reduce the power demand of the peak power system and improve the economics of system operation.

Key words: regional integrated energy system, gas heat pump, demand response, peak load shaving, economic dispatch
