Currently, high levels of output stochasticity in renewable energy and inefficient electrolyzer operation plague IESs when combined with hydrogen energy. To address the aforementioned issues, an IGDT-based economic scheduling strategy for integrated systems is put forth. Firstly, this establishes IES consisting coupled electricity, heat, hydrogen, gas taking production electrolyzer’s thermal utilization into account. Second, to minimize system’s overall operating costs, a deterministic model built by account stepped carbon trading mechanism demand response. Lastly, optimal dispatch using information gap decision theory under two strategies risk aversion seeking, uncertainty generation. CPLEX solver used solve proposed model. After effective use from loads response, results show that system emission reduced 2597.68 kg cost lowered 44.65%. The based on IGDT can effectively manage costs while maintaining control, all accommodating decision-makers’ varying preferences. This study provide useful reference research related low-carbon economy.

Two-Stage Robust Optimization of Integrated Energy Systems Considering Uncertainty in Carbon Source Load

Processes, Journal Year: 2024, Volume and Issue: 12(9), P. 1921 - 1921

Published: Sept. 6, 2024

Integrated Energy Systems (IESs) interconnect various energy networks to achieve coordinated planning and optimized operation among heterogeneous subsystems, making them a hot topic in current research. However, with the high integration of renewable sources, their fluctuation characteristics introduce uncertainties entire system, including corresponding indirect carbon emissions from electricity. To address these issues, this paper constructs two-stage, three-layer robust optimization model for IESs day-ahead intra-day. The analyzes emission intensity at grid-connected nodes, as well uncertainty photovoltaic, wind turbine, cooling, heating, electricity loads, expressed using polyhedral sets. It standardizes modeling internal equipment IES, introduces trading mechanisms, low-carbon economic model, transforming objective function constraints into compact form. column-and-constraint generation algorithm is applied transform single-layer main problem two-layer subproblem iterative solution. Karush–Kuhn–Tucker (KKT) condition used convert linear programming model. A case study conducted on park shows that while introduction increases system costs compared deterministic optimization, scheduling strategy more stable, significantly reducing impact system. Moreover, proposed reduces total by 5.03% 1.25% scenarios considering only source load uncertainty, fully verifying method improves performance

Optimal Multienergy Management for Networked Electricity–Hydrogen Hybrid Charging Stations: A Vehicle‐Level Auction Approach

International Transactions on Electrical Energy Systems, Journal Year: 2025, Volume and Issue: 2025(1)

Electricity and hydrogen have emerged as viable alternatives to traditional fossil fuels, playing a crucial role in clean sustainable transportation solutions. The rapid growth of vehicles (HVs) electric (EVs) has significantly increased the demand for electricity–hydrogen hybrid charging stations (HCSs). Compared existing literature that predominantly focuses on optimal energy management from system‐level perspective, this paper explores power multiple HCSs multienergy trading between vehicles. In proposed mechanism, EVs HVs are enabled strategically submit their offer prices maximize utilities. Based these prices, aggregator allocates electricity determines final payments vehicles, aiming social welfare within system, subject operational constraints HCSs. theory Vickrey–Clarke–Groves (VCG) mechanism is employed design mechanism. Furthermore, we introduce concept information rents address potential budget imbalances aggregator, enhancing economic stability system. We also provide theoretical proofs properties which include truthfulness, individual rationality, maximization. Simulation results demonstrate effectiveness verify its three properties.
