Optimum Coordination Approach for Directional Overcurrent Relays in Interconnected Power Systems Considering Uncertainty in Photovoltaic Generation

IEEE Access
Optimizing the sensitivity and speed of the overcurrent protection system in the presence of distributed generation units while also ensuring the cost-effective design of the fault current limiter (FCL) represents great challenges for engineers.

Enhancement of the operating time of the overcurrent relay of the distribution network with high-level penetration of renewable energy sources

Results in Engineering
The calculation of the output current of distribution generation (DG) units interfaced with an inverter during the fault is a major issue for isolated and grid-connected distributed networks. The droop control inverter interfaced DG has controlled output
