Abstract

The basic objective of this paper is to present the relevant aspects of an advanced methodology for steady‐state security assessment of power systems. This methodology consists of the following relevant parts: procedure for forming the unified external network equivalents, with adaptive buffer system selection, procedure for fast contingency selection and simple method for the fast and sufficiently accurate assessment of dynamic variation of power system frequency during the time of its primary control. For the potentially critical contingency, the continuation of iterative procedure is performed. Full contingency analysis is based on specially developed method, which enables successive solution of the load‐flow problem for a set of characteristic post‐dynamic quasi‐stationary states. The characteristics of the developed methodology are tested on the example of the existing electric power interconnection in the Balkans.

## Abstract This paper presents an algorithm for the parallel solution of the security constrained optimal power flow (SCOPF) problem in a decentralized framework, consisting of regions, using a price‐based mechanism that models each region as an economic unit. We first solve the distributed optima
