Abstract Fast and accurate parameter identification of the photovoltaic (PV) model is crucial for calculating, controlling, and managing PV generation systems. Numerous meta-heuristic algorithms have been applied to identify unknown parameters due to the multimodal and nonlinear characteristics of the parameter identification problems.
The simulation accuracy of PV models relies on the values of key model parameters. Unfortunately, these parameters are typically unavailable in the manufacturer’s data . Therefore, it is necessary to employ optimization algorithms to obtain accurate PV model parameters.
There are three commonly used PV models, including the single diode model (SDM) , double diode model (DDM) , and triple diode model (TDM) . The number of unknown parameters in the PV models will increase as more diodes are used in the PV model. The simulation accuracy of PV models relies on the values of key model parameters.
The performance of PV models highly depends on the values of unknown parameters. In order to obtain accuracy parameters, the parameter identification is converted into an optimization problem, which can be optimized by metaheuristic algorithms.
Experiment results demonstrate that DIODE can secure accurate parameters of PV models and achieve highly competitive performance on benchmark functions. Previousarticlein issue Nextarticlein issue Keywords Differential evolution Diversity improvement Parameter identification Photovoltaic model 1. Introduction
A total of 11 advanced MAs were selected as comparing algorithms to validate the performance of DIODE on PV models. In addition, performance evaluation of DIODE was also conducted by testing under universal test suites. A large test bed containing 72 benchmark functions from CEC2014, CEC2017, and CEC2022 was used to avoid the overfitting problem.
