Optimal Coordination of Dual-Setting Directional Over Current Relay in Microgrid Considering Multi-Parametric Characteristics

P. Niranjan; N.K. Choudhary; N. Singh; R.K. Singh

Articles in Press, Corrected Proof, Available Online from 28 December 2023


  Conventional overcurrent protection schemes may not be sufficient to provide the complete protection of microgrids, especially in the islanded mode (ISM) of operation. Directional overcurrent relays (DOCRs) in microgrid may malfunction due to significant changes in fault current level and change in topology ...  Read More

Optimizing Multi-objective Function for User-Defined Characteristics Relays and Size of Fault Current Limiters in Radial Networks with Renewable Energy Sources

M. Faghihi Rezaei; M. Gandomkar; J. Nikoukar

Volume 12, Issue 1 , January 2024, , Pages 42-53


  Installing the renewable energy sources (RESs) in distribution networks changes the fault current direction, increases the fault current level and, consequently, eliminates the protection coordination between the protective devices. Overcurrent relays are among the most important protective devices in ...  Read More

An Improved Optimal Protection Coordination for Directional Overcurrent ‎Relays in Meshed Distribution Networks with DG Using a Novel Truth Table ‎

H. Shad; M. Gandomkar; J. Nikoukar

Volume 11, Issue 3 , October 2023, , Pages 151-161


  To assure the security and optimal protection coordination in meshed distribution networks, clearing faults swiftly and selectively is an essential priority. This priority, when hosting distributed generations (DGs), becomes the main challenge in order to avoid the unintentional DGs tripping. To overcome ...  Read More
