In conventional optimal power flow (OPF), parameters of electrical components such as resistance and thermal ratings of the overhead lines, are assumed to be constant despite the fact that they are strongly sensitive to the weather effect (e.g., temperature or wind speed) which influences the accuracy of optimal power flow results. This paper introduces a weather-based optimal power flow (WB-OPF) algorithm with wind farm integration by considering the temperature related resistance and dynamic line rating (DLR) of overhead transmission lines. A method of calculating the current-temperature relationship of bare overhead lines, given the weather conditions, is presented as a set of coupled temperature and power flow equations. A simplified general model is proposed to calculate the dynamic line rating (DLR) for maximizing the utilization of wind power. A Primal-dual Interior Point (PDIP) method is developed to solve the WB-OPF problem. The effectiveness of the proposed method is evaluated and demonstrated in the paper by two example power systems.
