Comparison of queen honey bee colony migration with various MPPTs on photovoltaic system under shaded conditions

Shaded conditions cause a decrease in the performance of photovoltaic (PV) systems. In this situation, power versus voltage curve shows two maximum points, namely local (LMPP) and global (GMPP). The main challenge for extracting from PV system during shading is existence false or LMPP along with true GMPP. Traditional point tracking (MPPT) has faced hurdles overcoming situation. Therefore, paper describes implementation Queen Honey Bee Migration (or QHBM short) to track GMPP systems, which called MPPT. highlight simulation results MPPT on systems under various conditions.
 We implemented boost converter installed 1200 Wp system. conducted using MATLAB® five scenarios aim show shadows that might encounter reality. tested repeatedly then average value taken measure MPP tracking. used calculate efficiency, number iteration convergence time. also compared other methods, incremental conductance (IC) Particle Swarm Optimization (PSO). obtained PSO MPPTs outperform IC terms time iterations. oscillate since no knowledge Both know scouts particles, respectively. are better than cases
