Abstract The rapid growth of electric vehicles (EVs) and renewable energy sources (RES) is transforming modern power distribution networks. However, uncoordinated integration of EV charging stations and renewable generation may lead to voltage instability, increased power losses, and degradation of power quality. This paper proposes an advanced hybrid optimization algorithm combining Harris Hawks Optimization (HHO) and the Sine Cosine Algorithm (SCA) to determine the optimal allocation and sizing of EV charging stations and renewable energy sources in distribution systems. The hybrid HHO–SCA algorithm improves global search capability and convergence speed while avoiding premature convergence. The optimization objective minimizes total power losses, voltage deviation, and operational cost while satisfying network constraints. The proposed method is tested on the IEEE 33-bus distribution system. Simulation results demonstrate significant improvements in voltage profile, reduced system losses, and enhanced system reliability compared with conventional optimization techniques.
