Enhancing distribution generator impact mitigation using an adaptive protection scheme based on modified pelican optimization algorithm and active database management system

Abstract This paper addresses the challenge of protecting electrical networks in presence distribution generators (DGs). The use DGs affects fault currents, leading to miscoordination between protection relays and causing constraints on network reliability. To tackle this issue, authors propose an adaptive scheme (APS) based a modified pelican optimization algorithm (MPOA) active database management system (ADBMS). APS coordinates directional overcurrent distance relays, while MPOA simulates mating strategy includes internal equation. proposed is further upgraded with ADBMS save resources by storing relay settings calling them when state changes without running algorithms. effectiveness validated Institute Electrical Electronics Engineers (IEEE) eight‐bus test IEEE 14‐bus network. Results indicate that can effectively protect DGs, upgrade saves resources.
