چکیده

Renewable energy sources offer geographical opportunities for enhanced energy efficien-cy. However, the substantial integration of renewable energy production into distribution systems introduces uncertainties and technical complexities by impacting the network per-formance and protection mechanisms. Distributed generation (DG) enhances power grid efficiency, yet its influence on protection systems raises concerns about fault detection and isolation within active distribution networks. This study introduces a method to coordinate protection devices by inverter current control of distributed production sources during faults. The paper compares the impact of dispersed resources on flow dynamics during fault conditions. ETAP software simulations validate the proposed approach, addressing challenges in coordinating and regulating protection devices when integrating diverse re-sources into the network. This method restores coordination and enhances the reliability of protection systems. In summary, this research emphasizes the challenges of integrating re-newable energy into distribution systems, highlighting the need for effective protection co-ordination. The proposed method contributes to mitigating these challenges, ensuring de-pendable and efficient active distribution networks
