This paper presents a new method of obtaining an approximate optimized solution of the economic dispatch problem of a power system using the output of a standard loadflow computer program along with a geometric programming algorithm. This digital-computer method is much faster than the existing methods requiring only about thirty seconds on an IBM 360-75 system to obtain a loadflow solution as well as optimize the economic dispatch problem for a system of 203 buses, and requires little additional core storage over the requirements of the loadflow routine.
