为实现双碳背景下的低碳化发展，解决综合能源系统的多能供应及节能减排问题，提出含一种光热电站及氢储能的综合能源系统低碳优化运行策略。通过分析热能存储(thermal energy storage, TES)系统与氢储能系统联合运行，建立了多储能联供模型，有效地实现电-热能量的相互转移，提高能源利用率，优化系统的运行灵活性。将碳交易和碳税引入系统决策中，构建以购能成本、运维成本、碳交易成本等综合成本最小为目标的综合能源系统低碳调度优化模型。最后分析了不同场景运行，对优化模型进行仿真分析。结果表明，考虑TES和氢储能协调调度能够有效的降低运行成本、减少碳排放。
英文摘要:
In order to realize the low-carbon development under the double carbon background, solve the problems of multi-energy supply, energy saving and emission reduction of integrated energy system, a low-carbon optimized operation strategy of the integrated energy system including solar thermal power plant and hydrogen energy storage is proposed. By analyzing the combined operation of thermal energy storage (TES) system and hydrogen energy storage system, the multi-energy storage joint supply model is established to effectively realize the mutual transfer of electric-thermal energy, improve energy utilization rate and optimize the operation flexibility of the system. Carbon trading and carbon tax are introduced into system decision-making, and a low-carbon scheduling optimized model of integrated energy system is constructed with the goal of minimizing comprehensive costs such as energy purchase cost, operation and maintenance cost and carbon trading cost. The results show that the coordinated scheduling of TES and hydrogen energy storage can effectively reduce operating costs and carbon emissions.
