Application of Stability Analysis of Q(V )-Characteristic Controls Related to the Converter-Driven Stability in Distribution Networks

Research output: Contribution to journalResearch articleContributedpeer-review


As the amount of volatile, renewable energy sources in power distribution networks is increasing, the stability analysis of the latter is a vital aspect for network operators.
Within the STABEEL project, the authors develop rules on how to parameterize the reactive power control of distributed energy resources to increase the performance while guaranteeing voltage stability.
The work focuses on distribution networks with a high penetration of distributed energy resources equipped with Q(V)-characteristics.
This contribution is based on the stability assessment of previous work and introduces a new approach utilizing the Circle Criterion.
Herein, distributed energy resources can be modeled as detailed control loops or as approximations, derived from technical guidelines.
In addition, the wavelet transform is applied to RMS time series simulations to obtain a more realistic, less conservative reference.
With the aim of extending existing technical guidelines, the stability assessment methods are applied to various distribution networks.
