摘要

提出一种基于容量灵敏度的构网型换流器配置方法,在宽频范围内考虑换流器落点差异的影响。首先,基于回比矩阵的关键特征值衡量系统的稳定裕度。其次,计算关键特征值对不同落点构网型换流器的容量灵敏度,基于灵敏度筛选系统的薄弱节点,所述薄弱节点在构网型换流器的选址规划中具备更高的优先级;最后,通过仿真算例验证所提方法的有效性。

Abstract

In this paper, a configuration method of grid-forming converters based on capacity sensitivity is proposed, which considers the influence of the access positions of grid-forming converters in a wide frequency range. Firstly, the stability margin of the system is measured based on the key eigenvalues of the return ratio matrix. Secondly, the capacity sensitivity of the key eigenvalues to the grid-forming converters with different access positions is calculated. The weak nodes of the system are screened by the capacity sensitivity, and the siting planning of grid-forming converters prioritizes weak nodes. Finally, the effectiveness of the proposed method is verified by PSCAD simulation.
