This project presents a differential evolution (DE) based methodology to relieve congestion and improve quality and cost efficacy of generated power, formulating a penalty based congestion constrained OPF problem' in a hybrid thermal-wind power farm. Employing an approach of 'Demand sensitive loss factor' (DSLF) to select the worst possible inadvertent states of the system and the weakest bus of the system in active, reactive loading the algorithm attempts to reschedule the generators to bring down the individual line flows to provide better congestion management keeping in view of...
