A Hunter-Prey Algorithm Coordinating Mutual Benefit and Sharing and Interactive Learning for High-Efficiency Design of Photovoltaic Models

Abstract

It is crucial for the photovoltaic system to have an accurate model and well-estimated parameters to further increase conversion efficiency. Most existing methods for identifying photovoltaic model parameters have problems such as high computational cost, local optimum trouble, or difficulty in providing the best performance due to complex adjustments of algorithm parameters. To improve these defects, a hunter-prey optimization algorithm coordinating mutual benefit and sharing and interactive learning activities (EHPO) is proposed. First, based on hunter-prey optimization, timely information sharing with the mutual benefit and sharing mechanism was achieved when the algorithm was applied to search for prey, thus improving the searching precision and convergence rate of the algorithm. Second, hunters used the history optimization information and useful information from peers to guide the search direction, thus balancing the global and local development abilities of the algorithm. Finally, a lens imaging backward learning strategy was adopted to prevent the algorithm from falling into the local optimum, thus increasing the diversity of varieties and the probability of finding the global optimal solution. The simulation results of the single-diode model (SDM), double-diode model (DDM), triple-diode model (TDM), and other PV models in different environmental conditions show that the improved EHPO algorithm is more advantageous for parameter extraction than other advanced metaheuristic algorithms. This study demonstrates that EHPO is an accurate and reliable tool for predicting the parameters of PV models.

An Improved Differential Evolution for Parameter Identification of Photovoltaic Models

“…In [45], an improved artificial bee colony optimization algorithm based on the chaotic map theory (CIABC) was developed to fortify the search capability of ABC at PV parameter extraction. In [46], a hunter-prey optimization algorithm with reciprocity and sharing and learning interaction was presented to identify the unknown parameters of several PV models. Furthermore, Sharma et al [47] proposed an improved moth flame optimization technique with the opposite learning method and Lévy flight mechanism (OBLVMFO) to identify parameters of three PV panels, i.e., the STE 4/100 and SS2018P poly-crystalline, and LSM20 mono-crystalline modules.…”
