Framework for optimal power flow incorporating dynamic system security

الملخص EN

This paper introduces a novel framework and methodologies which are capable of tackling the complex issue of power system economy versus security in a practical and effective manner.

At heart of achieving such a challenging and far-reaching objective is the incorporation of the Dynamic Security Assessment (DSA) into production optimization techniques using the Transient Energy Function (TEF) method.

In addition, and in parallel with the already wellestablished concept of system security, two new concepts pertaining to power system performance will be introduced in this paper, namely the concept of system dynamic susceptibility, which measures the level of system weakness to a particular contingency and the concept of system consequent restorability, which measures the extent of contingency severity in terms of the required subsequent system restoration work should a particular contingency occur.
