The power flow analysis in a highly interconnected grid is a big problem for an electrical engineer. The next big obstacle is that of Economic Dispatch at the load side. The issue with Economic Load Dispatch (ELD) is with allocating the total generation to the individual generators in such a way that the total cost of generation at any time is at a minimum. In this project, the optimal cost of generation has been analyzed with a distributed slack bus model. In ordinary load flow method, the slack bus is bound to carry the entire extra burden of the system. In the proposed technique, the burden on slack bus shall be reduced and still maintain the equal incremental cost criteria. A new term called Participation factor shall be utilized to achieve the same as the total loss of the system at the end of iteration shall get distributed among all the generating units. Finally practical bus network problems shall be taken as case study and results shall be analyzed and compared with the existing ELD scheme to verify the usefulness of the proposed technique.
