The traditional N− 1 security assessment approaches give a limited perspective on the
degree of power system security. This study proposes a novel security assessment …

Voltage stability is an important factor that needs to be taken into account in the planning
and operation of modern power systems. From the voltage stability analysis point of view …

This paper presents the voltage stability based weak area clustering techniques in power
system. The techniques employed voltage stability analysis (VSA) and Line outage …

Voltage instability is a phenomenon that could occur in power systems due to stressed
conditions. The result would be an occurrence of voltage collapse leading to total blackout of …

In this paper, a new analytical method is presented for calculation of the “N-1 ″transmission
line outage post-contingency states of the power system, without any needs to iterate the …

Voltage ranking is an important part of power system security assessment. The commonly
used performance index method with a low exponent could suffer from masking effects. This …

The traditional static security analysis based on the data of one time section can not adapt to
the continuous state changing of power system appropriately. To improve the deficiency, a …

In allusion to the fact that the traditional off-line security analysis based on the data of one
time section can not adapt to the continuous state change of power system appropriately, a …

The constantly improvement of communication help the technology of WEB services find its
way to the power dispatching system. Gived WEB services is actively populized and applied …
