摘要：

The structure of synthesis load model for power system is one of the most basic and key issues in the field of load modeling. In simulation calculations of power system, the load model is directly connected to the high-voltage bus of substation. However, the loads are actually connected to power gird through the high-voltage distribution network, and the existing synthesis load modeling doesn't reflect this condition. In this paper, a load modeling method suitable for high-voltage distribution network is proposed. To avoid extra complexity, the equivalent model of high-voltage distribution network is integrated into the load model, and therefore an synthesis load model considering the distribution network structure is developed. The simulation analysis shows that the proposed synthesis load model has a significant improvement in model description ability, adaptation ranges of voltage and other aspects compared with the existing synthesis load models. The two structures are similar in the comprehensive performances, but have slight differences in the parameter stability and the maintenance of load bus voltage. © 2020 Automation of Electric Power Systems Press.
