State estimation has become a tool of vital importance in modern control centers. If the accuracy of the state estimation could be increased this will mean that a more reliable representation of the power system is obtained and the operation and control functions can make better decisions. This paper studies the influence of changes of the transmission lines resistance due to temperature on state estimation performance. The possibility to account for this effect in state estimation is shown by the use of Line Heat Balance equation and weather data. Show more
