Abstracts: The power flow analysis in a highly interconnected grid is a big problem for an electrical engineer. With the advancement in the technology, this issue has been tackled with greater accuracy and efficiency. Now the load flow and subsequent concerns are taken care by simulations in a minute. The next big obstacle is that of Economic Load Dispatch at the load side. In ELD, the unit commitment of each generator is taken into consideration to have adequate margin for reserve at any time. The second issue with 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 optimum cost of generation problem has been analyzed with a distributed slack bus model. In ordinary load flow analysis, 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 used to achieve the same as the total loss of the system at the end of iteration shall get divided among all the generating units. Two distinct 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.
