My Mtech project is on optimal location and size of DG in distribution system using particle swarm optimization. Therefore as already code is there with me.. i just need to little modify my code accordin g to cuckoo search algorithm......You can verify my project paper published in IJERT, Vol.1, Issue 10, December-2012, with the title “Analysis of Radial Distribution System by Optimal placement of DG using DPSO”. Let me complete your project...
