摘要：

Aiming at the impact of photovoltaic integration on system small disturbance stability, a solving method of damping ratio sensitivity based on random response surface method and perturbation method is proposed. The random excitation of photovoltaic output fluctuation is taken as the perturbation, and the damping ratio sensitivities are solved with photovoltaic accessed to grid on different nodes by the perturbation method. The optimum photovoltaic accessed node is selected according to the damping ratio sensitivity, the access location and capacity of photovoltaic power generation are determined through optimization method, and the optimum access mode of photovoltaic power generation is obtained. New England 10-generator 39-bus system and an actual power system in a western province are taken for examples, which verifies the effectiveness of the proposed method. © 2021, Electric Power Automation Equipment Press.
