Low-carbon economic dispatch of integrated energy system considering dynamic hydrogen price
To address the low consumption rates of high-proportion renewable energy against the backdrop of carbon peaking and carbon neutrality,we propose a low-carbon economic dispatch model for an integrated energy system with full considerations of dynamic hydrogen prices and power limits for two-stage electrolyzers.First,a power ceiling mechanism for the two-stage electrolyzer is built with the input electrolyzer's power ceiling dynamically adjusted based on hydrogen energy prices to achieve rational distribution and optimal electric energy use.Second,a multi-agent master-slave game model for low-carbon economic scheduling is developed to determine game hydrogen prices,maximizing benefits for upper integrated energy system agents,lower energy suppliers,and hydrogen energy users.Then,utilizing dynamic hydrogen pricing based on game theory principles along with solar utilization rates and clean energy proportions promotes wind&solar power accommodation and reduces carbon trading costs and hydrogen usage expenses.This mechanism is then incorporated into the aforementioned master-slave game model for secondary optimization scheduling.Finally,an example analysis demonstrates the effectiveness and feasibility of our strategy.
