Mohapatra, Anurag (2012) Distributed Slack Bus Algorithm for Economic Load Dispatch. BTech thesis.
The power flow in a highly interconnected grid is an ancient problem for an electrical engineer. With the advent of time of course, 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. 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 looked into with a distributed slack bus algorithm. In ordinary line flow analysis, the slack bus is asked to carry the entire residual burden of the system. In the proposed method, the burden on slack bus shall be eliminated and still maintain the equal incremental cost criteria. A new concept 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 generator buses. Two distinct bus networks were used as case studies and the results are compared and analysed to verify the usefulness of the proposed technique.
