Intensification of Available Transfer Capability Via Real Coded Biogeography Based Optimization

Decisive challenge for giving economical electricity to the end users in the restructured and rivalry electricity open market can be solved by the resolution and augmentation of Available Transfer Capability (ATC). In this paper, real coded biogeography based optimization (RCBBO) is used to scrutinize prevail of FACTS devices like TCSC and SVC in order to relieve congestion as well as boost the transferring of power at both normal and abnormal circumstances. And hence to improve the voltage profile in the system and reduces the transmission losses. The consequences have been concluded for whole and line contingency cases without and with FACTS device. The proposed technique aims to improve the real coded searing ability, avoid the prematurity of solution, improve the convergence characteristics and enhance the population diversity of the biogeography based optimization algorithm by using adaptive Gaussian mutation. The suggested algorithm will to provide a new way for Biogeography Based Optimization (BBO) to solve multi-objective optimization problems, have been tested on IEEE 30-bus and IEEE 118-bus system and the comparative results are made with existing population based methods.
