TL;DR: This work introduced the soft computing based estimation using Adaptive Neural Fuzzy Inference Systems (ANFIS) tool in MATLAB to estimate the module temperature of PV with respect to change of irradiance, ambient temperature, and wind velocity.
Abstract: The recent advantages in the thermal extraction schemes of Photovoltaic (PV) systems became more feasible for domestic applications. The amount of thermal energy available at the PV backside is the source for all thermal extraction/utilizing schemes. But, till now, there is no accurate theoretical method to find the module temperature by any mathematical equation to be adaptable for all the conditions. In this work, we introduced the soft computing based estimation using Adaptive Neural Fuzzy Inference Systems (ANFIS) tool in MATLAB to estimate the module temperature of PV with respect to change of irradiance, ambient temperature, and wind velocity.

Abstract: Solar energy, at the present time is considered as an important source in electricity generation. Electricity from the solar energy can be generated using solar photovoltaic (PV) modules. The maximization of solar power extracted from a PV module is of special concern as its efficiency is very low. The output power of a PV module is highly dependent on the geographical location and weather conditions such as solar irradiation, shading and temperature. To obtain maximum power from PV module, photovoltaic power system usually requires maximum power point tracking (MPPT) controller. In this paper, an adaptive neuro-fuzzy inference system (ANFIS) based maximum power point tracker for PV module has been presented. To extract maximum power, a DC–DC boost converter is connected between the PV module and the load. The duty cycle of DC–DC boost converter is modified with the help of the ANFIS reference model, so that maximum power is transferred to load. Due to the complexity of the tracker mechanism and non-linear nature of photovoltaic system, the artificial intelligence based technique, especially the ANFIS method, is used in this paper. In order to observe the maximum available power of PV module, the ANFIS reference model directly takes in operating temperature and irradiance level as input. The response of proposed ANFIS based control system shows accuracy and fast response. The simulation result reveals that the maximum power point is tracked satisfactorily for varying irradiance and temperature of PV module. Simulation results are provided to validate the concept.
