摘要
针对碳捕集、利用与封存(carbon capture, utilization, and storage,CCUS)项目中CO2泄漏源参数反演精度不足的问题,提出一种融合麻雀搜索算法(sparrow search algorithm,SSA)与粒子群算法(particle swarm optimization,PSO)的混合优化方法。首先,基于高斯烟羽扩散模型构建泄漏正演模型,分析泄漏速率、风速和大气稳定度对地表CO2浓度分布的影响规律;其次,结合SSA的全局探索能力与PSO的局部开发优势,建立泄漏源位置与泄漏速率的反演模型。仿真结果表明:SSA-PSO算法反演的泄漏速率相对误差仅为0.01%,泄漏源位置坐标的相对误差均为0.10%,相较于PSO、SSA、GA及GA-PSO算法,其泄漏速率反演精度显著提升,最大相对误差降幅达27.99%,泄漏源定位精度最大提升22.3%。实例验证进一步表明,该算法在泄漏速率与位置反演中的相对误差分别为10.50%、4.00%和3.00%,均优于对比算法,且计算效率更高。研究表明,SSA-PSO混合算法能够实现CCUS项目CO2泄漏源的快速精准定位,为泄漏应急响应与风险防控提供有效技术支撑。
Abstract
To address the issue of insufficient inversion accuracy of CO2 leak source parameters in CCUS (carbon capture, utilization, and storage) projects, a hybrid optimization method combining SSA (sparrow search algorithm) and PSO (particle swarm optimization) was proposed. First, a forward leakage model was constructed based on the Gaussian plume dispersion model to analyze the influence of leakage rate, wind speed, and atmospheric stability on surface CO2 concentration distribution. Then, combining the global search capability of SSA with the local development advantages of PSO, an inversion model for leak source location and leakage rate was established. Simulation results show that the SSA-PSO algorithm achieves a relative error of only 0.01% for leakage rate, and relative errors of 0.10% for leak source coordinates. Compared with PSO, SSA, GA, and GA-PSO algorithms, the leakage rate inversion accuracy is significantly improved, with a maximum relative error reduction of 27.99%, and leak source location accuracy increased by up to 22.3%. Case studies further demonstrate that the relative errors for leak rate and location inversion using this algorithm are 10.50%, 4.00%, and 3.00%, respectively, all better than the comparison algorithms, with higher computational efficiency. The study indicates that the SSA-PSO hybrid algorithm can achieve fast and accurate localization of CO2 leak sources in CCUS projects, providing effective technical support for emergency response and risk prevention of leaks.
