天然气消费量的影响机制对供暖季天然气的精准保供和运行调度至关重要,然而现有基于数据分析的研究方法普遍存在可解释性较弱的问题,无法深刻阐述影响供暖季天然气消费量变化的内在机理.基于动态系统理论基础,将天然气消费量变化的过程视为一个动态系统,因素影响消费量变化的过程作为系统内的状态变量,采用系统辨识方法构建状态空间模型分析状态变量的物理含义.以北方地区供暖季为例,构建了状态空间模型来分析温度变化对供暖季天然气消费量的影响,通过分析模型内部参数含义,揭示了天然气消费量的动态变化过程,旨在从机理层面分析状态变量和系统之间的因果关系来进行可解释性分析研究.所提出的模型提供了一个新的系统视角来理解和分析天然气消费行为,揭示了天然气消费量的动态变化模式,表明了温度滞后效应和累积消费需求在天然气消费预测中的重要性,为能源消费影响因素分析提供了新的研究方法.
Study on the Relationship between Temperature and Natural Gas Consumption Based on State-Space Model
Influencing mechanism of the natural gas consumption is crucial for ensuring accurate supply and operational scheduling during the heating season.However,existing data-driven research methods often suffer from weak interpretability,making it difficult to profoundly elucidate the underlying mechanisms driving changes in natural gas consumption during the heating season.Based on dynamic system theory,this study conceptualizes the process of natural gas consumption changes as a dynamic system,where influencing factors are treated as state variables within the system,and analyzes the physical significance of these state variables by the state-space model constructed using system identification methods.Taking the heating season in northern regions as an example,it examine the impact of temperature changes on natural gas consumption using the model,reveals the dynamic processes of natural gas consumption by analyzing the meanings of internal parameters within the model in order to provide interpretability by exploring causal relationships between state variables and the system from a mechanistic perspective.The proposed model offers a novel systemic perspective for understanding and analyzing natural gas consumption behavior,elucidating its dynamic patterns,which highlights the importance of temperature lag effects and cumulative consumption demand in forecasting natural gas consumption so as to provide a new methodological approach for analyzing energy consumption influencing factors.
