This paper is the first of a two-part paper presenting issues related to short term voltage stability problem and then providing possible solution options that can ensure the security of the system. Lately power system planners are frequently encountering voltage problems in short term. Placement of dynamic VAR device in the system is one preferred option. However, there is little research done in...
Dynamic security of power systems is a major concern during contingencies, especially in present environment when there is inadequate transmission line capacity and dynamic reactive power support. This paper addresses dynamic VAR allocation to ensure acceptable transient voltage performance and short-term stability against severe contingency. To filter out severe contingency, severity indices are...
