Optimized Scheduling of Integrated Energy Systems Accounting for Hydrogen Energy Multi-Utilization Models


To cope with the growing penetration rate of renewable energy and to enhance the absorption capacity of wind power, this paper investigates the applications of an Integrated Energy System (IES), Hydrogen Compressed Natural Gas (HCNG), and power-to-hydrogen (P2H) devices within the IES. It employs power-to-gas and gas blending with hydrogen to construct an efficient electricity–gas–electricity energy flow loop, establishing a Natural Gas–Electricity Coupling System (NGECS) model. On this basis, a coordinated scheduling method for gas–electric coupling systems using gas blended with hydrogen is proposed. A carbon trading mechanism is introduced to constrain carbon emissions, further reducing the system’s carbon footprint. Multiple scenarios are set up for a comparative analysis in order to validate the effectiveness of the proposed model. This study also analyzes the impact of different hydrogen blending ratios and methods on the low-carbon and economic performance of IES.
