Branch outage solution using particle swarm optimization
(2008)
For post outage MW line flows and voltage magnitude calculations most of the methods use linear methods because of their simplicity. Especially for reactive power flow calculations one can face high errors. In this paper ...
Gravitational search algorithm for post-outage bus voltage magnitude calculations
(2010)
Branch outage problem is one of the key problems in power system security analysis. This paper solves branch outage problem using a bounded approach. Local constrained optimization problem in the bounded approach is solved ...
Harmony search method based parallel contingency analysis
(2010)
Power system security management is one of the key problems in power system analysis. Power system management center operators need to simulate contingencies as fast as possible and take the remedial actions in time. These ...
Post-outage state estimations for outage management
(IFAC Secretariat, 2011)
Real time outage information is required to the utility operators for outage management process. In addition to some basic information regarding the outage post-outage system status will help to improve the response to ...
