The management of power systems has become more difficult than earlier because power systems are operatedcloser to security limits, environmental constraints restrict the expansion of transmission network and the need for longdistance power transfers has increased. The loading of a transmission network can be increased by maintaining propervoltage profile through injecting appropriate reactive power into the system. The existence of the multiple solutions in theoptimal placement of reactive power in the power system typically often get stuck at the local optimum rather than at theglobal optimum. Genetic Algorithms (GAs) are stochastic searching algorithms that make the searching process jumpsrandomly from point to point, thus allowing escape from the local optimum, and search for many sub-optimum points inparallel. This paper presents an evolutionary computation algorithm for enhancing voltage stability. GAs will determine themost vulnerable bus in the power system, where the Static VAR Compensator (SVC) is needed to be installed at that bus aswell as considering installation cost of SVC. The developed algorithms have successfully obtained the best solution foroptimal placement of SVC in the IEEE 9 buses system and TNB northern area 275kV 14-bus system. |
