Low-carbon economic dispatch of industrial park integrated energy system considering time-varying carbon emission factor

Abstract

Given the high carbon emission level of the industrial park integrated energy system， a low-carbon economic dispatch model of the integrated energy system considering the time-varying carbon emission factor is proposed. Firstly， to improve the carbon emission model of the whole process of electric energy production， the carbon emission characteristics of tie-line and energy storage charging and discharging are studied. Secondly， the low-carbon potential of load-side dispatchable resources is explored， and a dispatch model of load-side dispatchable resources under the incentive of price signals and time-varying carbon emission factor curve is constructed； a low-carbon economic dispatch model of the industrial park integrated energy system considering the time-varying carbon emission factor curve is constructed to optimize the system operation with the objective of minimum operation cost and carbon emission. The simulation results show that the low-carbon economic dispatch model can effectively reduce the carbon emission level of the system and reduce the total operation cost of industrial park.
