Loadability analysis based on short-circuit power

Abstract:

This study describes a loadability analysis in power systems based on short-circuit power (SSC) at a load bus as a parameter space. This analysis determines the maximum loadability based on a proposed voltage stability indicator called voltage-power stability indicator (VPSI). VPSI is calculated by processing two consecutive sets of voltage magnitude and power measurements, both recorded at the same bus of a power system. By maximising VPSI under load changes, one can obtain information concerning the SSC. Then, the loadability value can be calculated based upon SSC. The results demonstrate that a simple relation between the SSC and power load can be used to determine the loadability of the power system. This work highlights the advantage of obtaining the loadability in SSC parameter space because system changes or load changes produce the same effect into the SSC domain, allowing better determination of the maximum loadability.
