Low-carbon Dispatching Strategy of Integrated Energy System With Coordination of Green Hydrogen and Blue Hydrogen Based on Fine Modeling of Hydrogen Production Equipment
Under the background of"dual carbon",to reduce the cost of hydrogen energy utilization and carbon emissions,a low-carbon dispatching mode of green and blue hydrogen coordinated with the integrated energy system is proposed.Firstly,green hydrogen and blue hydrogen production-storage-use modules are introduced considering the economic and low-carbon complementarity between hydrogen production from electrolysis and natural gas.The power-efficiency dynamic characteristics of green hydrogen production equipment and the energy conversion process in blue hydrogen production are finely modeled to achieve efficient and coordinated utilization of different types of hydrogen energy.Secondly,increase hydrogen supply flexibility by optimizing the green and blue hydrogen ratio in the hydrogen load supply.Based on this,comprehensively considering the carbon trading mechanism,the life loss of the electrolyzer under fluctuating wind power and the constraints of each equipment,the economic dispatch model is constructed to minimize the total cost of the sum of wind power operation and wind curtailment penalty cost,energy purchase cost,electrolyzer life loss cost,blue hydrogen purification cost and carbon trading cost.Finally,an example analysis verifies the rationality of the proposed coordinated green and blue hydrogen optimization strategy.
