Abstract

This paper presents a mathematical model linearized to evaluate the Power Transfer Limit (PTL) for each concerned power corridor under dynamic security constraints. Based on a Normalized transient Energy Function (NEF), a stability index called Transient stability Time Margin (TTM) is introduced in the PTL model for Dynamic Security Assessment (DSA). In order to obtain the maximum capability of power transfer, a PTL computation strategy is developed, which is composed of contingency screening, sensitivity analysis and generation reallocation. Case studies on the 10-generator New England test power system are reported to show the effect of the proposed approach.
