This work presents a method for maximum power point tracking (MPPT) based on the particle swarm optimization (PSO) algorithm with variable step size in order to prevent steady-state oscillations. This will avoid the impact of partial shading conditions in the efficiency of photovoltaic (PV) systems. To optimize the power output of the solar panels a DC-DC boost converter is used.

This work presents a maximum power point tracking (MPPT) design for a photovoltaic (PV) system using a grey wolf optimization (GWO) technique. The problem of tracking the global peak (GP) of a PV array under partial shading conditions (PSCs) is attempted employing the GWO-based MPPT technique. The proposed GWO-MPPT algorithm is implemented on a PV system using MATLAB/SIMULINK. MATLAB Code and Simulink Model of Grey Wolf MPPT for Partial Shaded Solar PV system.
For maximum utilization of solar energy, photovoltaic (PV) power systems should be operated at the maximum power point (MPP) which can be achieved using maximum power point tracking (MPPT) methods. However, the occurrence of multi-peak on the P-V curve of a PV array due to the changing environmental conditions such as being partially shaded increases the complexity of the tracking process. The global MPP cannot always be achieved by conventional MPPT methods. Therefore a novel MPPT method for PV systems using the flower pollination (FP) algorithm is proposed in this work and the Levy flight is used to improve the convergence of FP algorithm. MPPT model of the PV system is established in MATLAB to verify the effectiveness of the proposed method. MATLAB Code and Simulink Model of Flower Pollination MPPT for Partial Shaded Solar PV system
The work presents a review about Maximum Power Point Tracking (MPPT) of PV system based cuckoo search algorithm. Cuckoo search (CS) provides several advantages such as the process of tuning parameters is few with high efficiency besides fast convergence. The cuckoo search uses a random walk according to levy flight in the searching process. The results show that CS can track MPP under different operating conditions.
