Abstract
ABSTRACTThe dynamic thermal rating (DTR) can improve the thermal load capacity of transmission lines. The integration of DTR into power system scheduling achieves full utilization of the line load capacity. Thus, this paper proposes the concept of advanced DTR and applies it to the advanced scheduling of power system. Based on advanced thermal rating, combining with conductor temperature, safe running time, and system power flow, the advanced scheduling is realized to achieve the predictive use of line thermal load capacity. In addition, based on the wind power forecast, the advanced scheduling in the wind turbine system is studied. The influence of the randomness of wind power on the advanced scheduling is presented. The results prove that the advanced scheduling based on advanced thermal rating can improve the economy and safety of power grid operation.
