| 中文摘要: |
| 温控负荷(temperature controlled loads, TCLs)因其显著的热惯性特性和调节潜力,在需求响应(demand response, DR)研究中具有重要意义。针对现有模型难以全面捕捉温控负荷时变特性及调节能力差异的问题,提出了一种基于数据驱动的参数辨识与需求响应能力评估方法。首先,基于二阶等效热参数(equivalent thermal parameters, ETP)模型,构建线性辨识方程,并引入自适应遗忘因子的多层递推最小二乘算法,实现动态等效参数矩阵的在线辨识。同时,针对投切型负荷与连续可调型负荷的不同调节特性,设计了相应的需求响应能力评估策略。仿真结果表明,所提方法能够精准辨识负荷参数并准确评估需求响应能力,为温控负荷建模及电网辅助服务优化提供了可靠支持。 |

| Temperature controlled loads (TCLs) are of significant importance in demand response (DR) research due to their remarkable thermal inertia and regulation potential. Addressing the limitations of existing models in fully capturing the time-varying characteristics and regulation capacity differences of TCLs, a data-driven parameter identification and demand response capability evaluation method is proposed. Based on the second-order equivalent thermal parameter (ETP) model, a linear identification equation is constructed, and a multi-layer recursive least squares algorithm with an adaptive forgetting factor is introduced to achieve online identification of the dynamic equivalent parameter matrix. Furthermore, tailored demand response capability evaluation strategies are designed for switching loads and continuously adjustable loads, considering their distinct regulation characteristics. Simulation results demonstrate that the proposed method can accurately identify load parameters and evaluate demand response capabilities, providing reliable support for TCL modeling and optimization of grid ancillary services. |
