SGER AWARD: POWER SYSTEM LOAD MODELING CONCEPTS

9318695绍尔本项目将研究负荷建模的基本原理，为通用负荷表示法建立理论基础。 研究将从时间尺度分离和奇异摄动的框架作为静态模型的主要数学基础。 由此，将检查诸如频率和电压依赖性的特性。 然后将研究动态负载模型，以确定哪种结构能够捕获重要的物理负载特性，同时还保持计算效率。 需要澄清的问题包括在准静态近似下瞬态过程中负载电压频率和负载电流频率之间的差异。 将研究准静态负载功率对母线电压和其他动态量的适当依赖性。 ***

9318695 Sauer This project will investigate the fundamental principles of load modeling to establish a theoretical basis for generic load representations. The investigation will work from the framework of time-scale separation and singular perturbation as the primary mathematical basis for static models. From this, characteristics such as frequency and voltage dependence will be examined. Dynamic load models will then be investigated to determine which structure captures the important physical load characteristics while also remaining computationally efficient. Issues which will require clarification include the differences between the frequency of load voltage and the frequency of load current during transients with the quasistatic approximation. The proper dependence of quasi-static load power on bus voltage, and other dynamic quantities will be investigated. ***
