This paper presents a power flow algorithm for electric power system considering the transmission line conductor’s temperature variation. A heat balance equation of line conductor based on weather environment and power loss of line is used to calculate the transmission line temperature. It is assumed that the weather data, i.e. the ambient temperature, the wind speed, the wind direction and the solar radiation, are available from weather measurement. The bus voltage magnitudes, the phase angles, and the transmission line temperatures are the state variables of the power flow problem. Simulation results on the IEEE 14-bus and 118-bus systems indicate that the proposed algorithm provides more accurate results than that obtained by the conventional power flow algorithm.
