Novel Grass Hopper optimization based MPPT of PV systems for complex partial shading conditions

•Grass Hopper Optimization (GHO) based MPPT is proposed for partial shading conditions.•GHO is compared with P&O, DFO, ABC, PSO, PSOGS, and CS.•Simulations demonstrate the superiority of GHO in tracking time, settling time, etc.•The robustness and sensitivity of GHO is confirmed by a statistical...
