Study on power flow with considering temperature configuration

In the process of transmission and distribution, power network produces a certain amount of power loss. Although resistance of branch is very sensitive to temperature produced by loss, the system has been always constant. In this paper, a new temperature power flow method is proposed, aiming at the problem of accurate theoretical calculation of transmission line loss. Through analyzing the temperature sensitivity of line loss, the branch affected by temperature sensitivity greatly is found to carry on the configuration of temperature measurement. It can effectively simplify temperature power flow calculation, and the result is close to the actual value. The simulation results demonstrate the validity and feasibility of the proposed method.
