SBIR Phase I: Development of a Path Independent Power System Voltage Stability Analysis Tool

9860977电力工业的放松管制和改组导致许多新的参与者试图利用高压电力传输系统。输电系统容量受到许多不同机制的限制，包括：(1)输电线路的热限制；(2)母线电压限值；(3)暂态稳定约束；(4)需要保持系统电压稳定。目前，存在许多有用的工具来访问前三个约束。在这个项目中，PowerWorld公司将开发一种新的软件工具，该工具利用路径独立模型使用能量方法进行电压稳定性评估。能量方法的优点包括路径独立性，能够提供特定区域电压稳定性的测量，以及相对较低的计算需求。

9860977 Deregulation and restructuring in the electric power industry is resulting in many new players attempting to utilize the high voltage electric transmission system. Transmission system capacity is limited due to a number of different mechanisms including: (1) transmission line thermal limits; ( 2) bus voltage limits; (3) transient stability constraints; and (4) the need to maintain system voltage stability. Presently, a number of useful tools exist to access the first three constraints. In this project, PowerWorld Corp. Inc. will develop a new software tool, which utilizes a path independent model for voltage stability assessment using energy method approaches. Advantages of energy methods include path independence, ability to provide measures of voltage stability in particular regions and potential for relatively low computational requirements.
