Relay Coordination in Distributed Power System Network Using Renewable Energy

The integration of renewable energy sources into power distribution networks presents significant challenges for relay coordination, essential for protecting the network from faults and ensuring reliable operation. This paper provides an in-depth analysis of relay coordination principles under fault conditions in a distributed power system using ETAP software. Key analyses, including load flow, short circuit, and fault analysis, were conducted to evaluate the reliability of the developed model. Utilising the Newton-Raphson algorithm, the ETAP software adjusts relay settings in real-time to ensure optimal performance. The study's findings demonstrate the model's effectiveness in maintaining network stability and reliability amidst the dynamic nature of renewable energy sources, highlighting the critical importance of advanced relay coordination strategies in modern power systems.
