Abstract
This manuscript investigates protection mechanisms for microgrids with distributed generation (DG) as of 2016, emphasizing adaptive, coordinated, and communication-assisted schemes. A comprehensive review of conventional overcurrent and differential protection methods is presented, followed by analysis of emerging synchrophasor-based and communication-enabled techniques. The study employs a mixed-methods approach comprising theoretical modeling, statistical analysis, and simulation research using MATLAB/Simulink to evaluate protection performance under various fault scenarios. Five research objectives guide the inquiry, focusing on fault detection speed, selectivity, reliability, coordination, and adaptive response. Statistical analysis of protection coordination indices is summarized in a table. Simulation results demonstrate that adaptive reclosing and synchrophasor-aided schemes significantly reduce fault-clearing times while maintaining system stability. The conclusions highlight the trade-offs between simplicity and adaptive complexity, and propose directions for future enhancements within the engineering constraints of 2016.
