9409676 Lesieutre The project aims to develop a systematic, mathematically rigorous method for the construction of physically-based dynamic load models. These models will increase the accuracy of power systems studies and improve power system operations by enabling more accurate calculation of steady-state and dynamic response. A model capturing the physical characteristics of an induction motor will be constructed and then used to identify which load model, among the widely varying models that appear in the literature, is most suitable for voltage stability studies. Steady-state and transient stability studies will be performed to examine the effect of the load. Following this example and using knowledge of significant load components, the researchers will construct a general model taking into account the composition of the load. The aggregation of dissimilar components and the representation of the model in terms of meaningful power system variables will be accomplished through a series of nonlinear transformations. The resulting model will retain the critical dynamic characteristics of the individual load components. ***

9409676 Lesieutre该项目旨在开发一种系统的、数学上严格的方法来构建基于物理的动态负荷模型。这些模型可以更准确地计算电力系统的稳态和动态响应，从而提高电力系统研究的准确性，改善电力系统的运行。将构建一个捕获感应电机物理特性的模型，然后使用该模型在文献中出现的各种模型中确定哪个负载模型最适合于电压稳定性研究。将进行稳态和暂态稳定性研究，以检查负载的影响。按照这个例子，并利用重要载荷分量的知识，研究人员将构建一个考虑载荷组成的通用模型。通过一系列的非线性变换，将不同的分量集合在一起，并用有意义的电力系统变量表示模型。生成的模型将保留各个载荷组件的关键动态特性。***
