Abstract: This paper attempts to a basic concept for a modified power flow analysis with a sense of the economic load dispatch to remove the concentrated burden of the slack bus. The power flow calculation in the proposed method is incorporated into the economic load dispatch (ELD). Furthermore, the proposed method eliminates not only the burden of a slack bus, but also maintains ‘an equal incremental cost’ in the economic load dispatch sense in this paper. Both the IEEE 14-bus and IEEE 39-bus systems are used to verify the usefulness of the proposed technique. [Copyright &y& Elsevier]
