Abstract:

The integration of distributed energy resources (DERs) into distribution systems greatly increases the system complexity and introduces two-way power flow. Conventional protection schemes are based on local measurements and simple linear system models and cannot handle the new complexity and power flow pattern of systems with high DER penetration. Therefore, in this paper, we propose a data-driven protection design framework to address the challenges induced by DERs. To address the issue of limited data availability under fault conditions, we adopt the support vector data description (SVDD) method, a commonly used one-class classifier, for distribution system fault detection. The proposed method is tested under the IEEE-13 and IEEE-123 node Test Feeders and the simulation results demonstrate that our proposed SVDD-based fault detection method is much more resilient to DERs in comparison with the conventional protection.
