Optimal Scheduling of Power-to-ammonia Integrated Energy Systems Considering Demand Response
摘要
Abstract
To enhance the low-carbon performance and economic efficiency of the industrial park integrated energy systems,this paper proposes an optimal scheduling model for a power-to-ammonia integrated energy system considering demand response.Firstly,it introduces a two-stage power-to-ammonia process based on power-to-gas methane production,utilizing surplus energy to produce ammonia.To further reduce system carbon emissions and operational costs,the produced ammonia reacts with carbon dioxide to synthesize urea.Secondly,demand response is categorized into price-based(using a price elasticity matrix)and substitution-based(through electricity-heat conversion)types according to load-side characteristics,forming a demand response mechanism.Finally,the paper applies the tiered carbon trading mechanism to constrain system carbon emissions and establishes an objective function to minimize the total costs,including gas procurement cost,carbon trading cost,coal consumption cost,wind curtailment cost,operation and maintenance cost and urea revenue.Multi-scenario comparative analysis demonstrate that the proposed system,through power-to-ammonia and urea synthesis,not only ensures economic benefits but also significantly reduces carbon emissions.Additionally,demand response effectively lowers energy procurement costs by adjusting supply-demand relationships.关键词
