This article presents a fast load flow algorithm considering the effect of frequency deviation on loads and generator outputs. The model was developed for and applied to a dispatcher training simulator (DTS) in the People's Republic of China. In order to meet the real time requirements of DTS, new solution techniques have been suggested to handle non-symmetric nature of the load flow Jacobian matrices resulting from the presence of the frequency deviation forms. The suggested methods reduce the memory requirement and provide faster solution. Results have been obtained on a 220 kV, 67 bus and another 22 bus provincial power system networks in China.
