Practical small signal stability region of large power grid based on interface power flow
摘要
Abstract
Based on interface power flow, a practical mode of small signal stability region is proposed for large power grid. In the process of modeling, a boundary point searching strategy in interface power flow space is given and an approach to optimizing security region boundary is suggested by distinguishing dominant mode. The concrete modeling process is described in Central China Grid and its correctness and practicality are identified in the application of basic operating points during inundation. Researching security region in interface power flow space accords with the habit of power safety monitoring and power operation dispatch. The practical mode based on interface power flow can simplify the calculation of stability region and satisfy the engineering demands well. Besides, the influence trend of interface power flow on system stability can be judged by hyperplane coefficients, which provides effective information for safety monitoring of power system.关键词
