摘要:

“双碳”战略背景下,可再生能源渗透比例不断提升,灵活性资源缺乏问题日益严重.为构建安全、高效、低碳的清洁能源系统以应对这一挑战,提出一种考虑多灵活性资源联合运行的综合能源系统优化配置方法.首先,对电转气设备的两阶段运行进行精细化建模,引入掺氢燃气轮机和电转气设备协同运行,以充分利用H2的低碳特性.同时,通过碳捕集设备向电转气设备提供碳原料,实现了CO2的循环利用,从而构建了以氢能为核心的灵活性资源联合运行框架.然后,针对可再生能源出力不确定性问题,通过Elbow法确定了最优聚类数目,并利用K-means聚类算法得到风速的典型场景.在此基础上,以投资成本、运维成本、置换成本、环境惩罚和弃风惩罚成本之和最小为目标,综合考虑设备约束、能量平衡约束及灵活性约束,建立优化配置模型.为解决模型的非线性问题,采用大M法将其线性化处理并完成模型求解.最后,基于中国西南某地区实测数据进行算例验证,结果表明:所提方法使综合能源系统的总成本降低了10.22%、新能源渗透率提高了6.01%、环境惩罚成本降低了2.65%,有效提升了系统的经济性和新能源消纳量,同时显著降低了系统碳排放水平.

Abstract:

Under the “carbon peaking and carbon neutrality” strategy, the penetration ratio of renewable energy is increasing, while the lack of flexible resources becomes a growing challenge. To address this and build a safe, efficient, low-carbon, and clean energy system, an integrated energy system (IES) optimization allocation method is proposed considering the joint operation of multiple flexibility resources. First, the modeling of the two stages of the power-to-gas equipment is refined, with the introducation of the coordinated operation of the hydrogen-doped gas turbine and the power-to-gas equipment to make full use of the low-carbon characteristics of H2. Carbon raw materials are provided for the power-to-gas facilities through carbon capture equipment realizing the recycling of CO2, thereby establishing a coordinated operation framework for flexible resource with hydrogen energy as the core. Then, aimed at the uncertainty of renewable energy output, the optimal clustering number is determined by Elbow method, and typical wind speed scenarios are obtained by K-means clustering algorithm. On this basis, an optimal allocation model is established with the objective of minimizing the sum of investment cost, operation and maintenance cost, replacement cost, environmental penalty, and wind abandonment penalty cost, taking into account equipment constraints, energy balance constraints, and flexibility constraints. To solve the nonlinearity, the large M method is adopted to linearize the model and complete the model solution. Finally, the method proposed is validated through an example based on measured data from a region in southwest China. The results show that the total cost of the IES is reduced by 10.22%, the penetration rate of new energy is increased by 6.01%, and the cost of environmental penalties is reduced by 2.65%. The proposed method effectively improves the economy of the system and the consumption of new energy, and significantly reduces system carbon emissions.
