چکیده

The conventional practice for usage of distributed generation(DG) is in distribution system for loss reduction, voltage profile improvement etc. Recently the distributed generations were used in transmission network as well for overall performance improvement i.e. reduction in losses, reduced cost of electricity, congestion management, improvement in voltage levels. The practice of distribution generation in transmission system is effective if its location and rating of generation is scaled up. In this paper for optimal location of DG, fuzzy inference system is proposed which will decide the DG location. For optimal sizing of DG, differential evolution (DE) technique is proposed. The results were simulated on IEEE-30 bus transmission network. The results are compared with the results obtained by firefly algorithm.
