To further optimize the low-carbon economy of integrated energy system (IES), this paper establishes a two-stage P2G hydrogen-coupled electricity–heat–hydrogen–gas IES with carbon capture (CCS). First, refines two stages and introduces hydrogen fuel cell (HFC) storage device to fully utilize in first stage power-to-gas (P2G). Then, ladder trading mechanism is considered CCS introduced reduce system’s emissions while coupling P2G. Finally, adjustable thermoelectric ratio characteristics combined heat power unit (CHP) HFC are improve utilization efficiency operating costs. This set up arithmetic examples analyze from several perspectives, results show that introduction can by 41.83%. In CCS-containing case, refining it lead 30% reduction 61% wind abandonment costs; consideration CHP ratios result 16% purchased

Energy Science & Engineering, Год журнала: 2025, Номер unknown

Опубликована: Фев. 23, 2025

ABSTRACT In integrated energy systems (IESs) with high share of renewable energy, converting excess electrical into hydrogen (H 2 ) and mixing it natural gas (NG) offers numerous advantages has become a key research focus. However, IES operations are influenced by various factors, such as equipment performance, flow dynamics, load management, which often overlooked in traditional optimization approaches. This study develops novel hydrogen‐compressed (HCNG)‐IES model operational strategy to address these challenges. An equivalence framework is established between electricity hybrid gas, enabling the creation an equivalent circuit integrating electricity, heat, HCNG, H , NG. captures intricate interactions dependencies amongst equipment, multi‐energy flow, consumption loads. optimized proposed, leveraging variable content mixture adaptable thermal loads, while accounting for inertia storage building maintain supply–demand balance. Case studies reveal that incorporating HCNG technology increases resources utilization, reducing costs, carbon emissions, primary 23%, 24%, respectively. Moreover, compared conventional NG‐IES focused solely on output, proposed HCNG‐IES approach achieves reductions 28.12% 24.36% 39.13% consumption.

Operation Optimization of Regional Integrated Energy Systems with Hydrogen by Considering Demand Response and Green Certificate–Carbon Emission Trading Mechanisms

Energies, Год журнала: 2024, Номер 17(13), С. 3190 - 3190

Опубликована: Июнь 28, 2024

Amidst the growing imperative to address carbon emissions, aiming improve energy utilization efficiency, optimize equipment operation flexibility, and further reduce costs emissions of regional integrated systems (RIESs), this paper proposes a low-carbon economic strategy for RIESs. Firstly, on supply side, conversion devices are utilized enhance multi-energy complementary capabilities. Then, an demand response model is established side smooth load curve. Finally, consideration given RIES’s participation in green certificate–carbon trading market system emissions. With objective minimizing sum operating costs, optimization that considers electricity, gas, heat, cold coupling established, CPLEX solver toolbox used solving. The results show coordinated sides while considering complementarity effectively reduces enhancing efficiency operations.
