Computation of Steady State Nodal Voltages for Fast Security Assessment in Power Systems 10.1109/PQ.2014.6866783

Møller, Jakob Glarbo; Jóhannsson, Hjörtur; Østergaard, Jacob

Proceedings of Ieee Electric Power Quality and Supply Reliability Conference 2014 — 2014, pp. 51-55

Development of a method for real-time assess-ment of post-contingency nodal voltages is introduced. Linear network theory is applied in an algorithm that utilizes Thevenin equivalent representation of power systems as seen from every voltage-controlled node in a network. The method is evaluated

Stochastic Quantum Power Flow for Risk Assessment in Power Systems

Sævarsson, Brynjar; Jóhannsson, Hjörtur; Chatzivasileiadis, Spyros

This paper introduces, to the best of our knowledge, the first quantum computing methodology for stochastic power flow. Stochastic power flow is widely used in power system operation and planning to study the impact of stochastic factors, such as uncertain generation, load, or contingencies

An Improved On-line Contingency Screening for Power System Transient Stability Assessment 10.1080/15325008.2017.1310953

Weckesser, Johannes Tilman Gabriel; Jóhannsson, Hjörtur; Glavic, Mevludin; Østergaard, Jacob

Electric Power Components and Systems — 2017, Volume 45, Issue 8, pp. 852-863

the simulation can be terminated after a few hundred milliseconds of simulated system response. The method's outcome is an assessment of the system's stability and a classification of each considered contingency. The contingencies are categorized by exploiting parameters of an equivalent one machine infinite bus
