      This paper presents a study performed to investigate the steady state and dynamic state performance of the UPFC device in between KSA and Kuwait. The main objective of this work was to identify and determine the UPFC impact on GCC power grid operations and control for different transmission contingencies. This study aims to develop a model and to simulate for different operating and control parameters with and without UPFC system, to evaluate the effectiveness of the UPFC device on the GCC power grid. The simulated results presented herein clearly demonstrate enhancement to power flow, power angle and stability margin in the GCC interconnection. This work also shows additional benefits principally, reduction of losses, increase of the load ability, and enhancement of the sustainability of the GCC interconnection.

  • Congestion Management Using Real and Reactive Power Rescheduling Based on
           Big Bang-Big Crunch Optimization Algorithm

    • Abstract: Congestion Management Using Real and Reactive Power Rescheduling Based on Big Bang-Big Crunch Optimization Algorithm
      Pages 109-118
      Author Farzad VazinramMajid GandomkarMehdi Bayat Mokhtar
      With appearance of deregulated electricity markets, line congestions in transmission systems is considered as critical problem for power system which may prevent dispatching all of the contracted power transactions. Many studies have been carried out to express techniques for congestion management (CM). In this paper real and reactive power rescheduling of generators approach is utilized. This method includes two steps. First one is optimum selection of generators on the basis of sensitivities of generator to power flow on congested line/lines. Next step is optimal rescheduling of generators and identification of capacitors required to provide real and reactive power support for CM. Optimization process in this paper is carried out using big bang-big crunch (BB-BC) algorithm which is improved by particle swarm optimization (PSO) method as hybrid BB-BC (HBB-BC) optimization for the first time. Effectiveness of proposed method has been tested on IEEE 30-bus system, the 39-bus New England system, and 75-bus Indian system and compared with the other proposed methodologies.
