Modern Distribution Network Protection (MDNP) Research Laboratory

In recent years, the paradigm of active distribution systems is being realized by the innovations in the small-scale distributed energy resources (DER) such as photovoltaics, wind turbines, fuel cells, and storage devices. Development of an efficient protection strategy is of great importance for the modern distribution network operation to prevent power loss and serious threats to the human life and network equipment. The current focus of “Modern Distribution Network Protection Laboratory” located at Department of Electrical Engineering, Najafabad Branch, Islamic Azad University is on the following topics.

- Fault detection in islanded AC microgrid with 100% electronically-interfaced generation units;

- Protection coordination of distribution networks with high penetration of distributed generations;

- Protection of DC microgrids in both grid-connected and islanded modes of operation;

- Current limiting of microgrid converters;

- Protection of photovoltaic arrays; and

- High impedance fault detection.

- Power sharing among electronically-interfaced generation units to avoid circulating currents.
