Penetration level of distributed energy resources with anti-islanding criteria and secure operation of power system

摘要

Many recent blackouts might raise a concern on how the introduction of distributed energy resources or distributed generation (DG) into the network influences its secure operation in terms of dynamic performance. The anti-islanding criteria of DG may harm the secure operation of the power system. In this paper, the maximum penetration level of DG is determined using a dynamic study. Tested systems are used to study. The results show that the protection settings have an influence the maximum penetration of DG and the system secure operation.
