Enhanced fault protection coordination in wind-solar distribution grids utilizing improved hyper spherical search based optimization.

ABSTRACT: The incorporation of renewable energy sources (RES) into distribution networks presents considerable hurdles for protective relay coordination due to variable fault currents and swiftly altering operational conditions. This paper introduces an Improved Hyper Spherical Search Algorithm (IHSSA) designed for optimal relay coordination in renewable energy source-integrated power systems. The IHSSA improves the conventional hyperspherical search method by integrating dynamic adjustment mechanisms that adaptively balance exploration and exploitation, facilitating quicker convergence and more accuracy in addressing intricate, high-dimensional optimization challenges. The algorithm's efficacy was assessed using a realistic 220/6.6 kV substation model that services a hybrid wind-solar distribution
