IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.This study introduces Gradient Jellyfish search optimization (GJSO) as a new optimization approach for optimal reactive power dispatch (ORPD) in electric networks. The GJSO methodology enhances standard JSO techniques by integrating the Local Escaping Operator.

Enhanced GSA‐Based Optimization for Minimization of Power Losses in Power System
Mathematical Problems in Engineering, Volume 2015, Issue 1, 2015., 2015 Gravitational Search Algorithm (GSA) is a heuristic method based on Newton’s law of gravitational attraction and law of motion. In this paper, to further improve the optimization performance of GSA, the memory characteristic of Particle Swarm Optimization (PSO) is employed in GSAPSO for searching a better solution.
