An Improvement GWO-P&O Algorithm Based MPPT for PV System under Partial Shading Condition

In a PV system, techniques are needed to maximize the output of electrical powerThe Maximum Power Point Tracking (MPPT) method is one of the methods used to locate the PV curve's maximum power coordinate point (MPP). PV system operation can experience uniform irradiation conditions (UIC) and partial shading conditions (PSC) depending on the environment. The use of conventional MPPT techniques such as P&O can work well in UIC conditions but will have difficulties when PV experiences PSC conditions. On the other hand, optimization methods such as IGWO can find GMP in PSC conditions. To overcome this problem a hybrid model of IGWO and P&O based on metaheuristic algorithms is used in this paper. Based on the simulations that have been carried out, it can be summarized that the proposed MPPT algorithm, namely the IGWO-P&O hybrid, can increase MPPT speed and accuracy, as well as reduce oscillation power.
