Abstract

Aiming at the voltage stability problem of power grid after large-scale integration of Distributed Generations (DGs), an optimal configuration method of reactive power compensation device is proposed. Firstly, the weak voltage nodes are selected by using the new energy short-circuit ratio index, and then a calculation index of average electrical distance is proposed. By calculating the average electrical distance between the alternative installation nodes and the weak nodes, the installation node of reactive power compensation device is determined. Finally, the maximum capacity of compensation device and the allowable amount of disconnection of DG is taken as the constraint condition, the configuration method of reactive power compensation device with optimal compensation effect is obtained by calculation. Taking an actual power grid in China as an example, it is found that the proposed method can effectively solve the problem of DG disconnection due to low voltage or high voltage ride through failure, and the effectiveness of the proposed method is verified.
