ANFIS as a method for determinating MPPT in the photovoltaic system simulated in MATLAB/Simulink

Photovoltaic systems as part of larger distribution systems for the production of electricity have non-linear current-voltage characteristics. These characteristics depend on the temperature of the solar cells and insolation of panels. The method for the search of the maximum power or MPPT is widely known, and there are many offered algorithm solutions. The aim of this paper is to present ANFIS (Adaptive Neural Fuzzy System Inference) as a method of computer intelligence in the search function of maximum power or maximum utilization of the PV system, without prior knowledge of the system. MPPT ANFIS will be located between the PV panels and devices for voltage regulation. Inputs used to go inside the fuzzy regulators and outputs of the fuzzy regulators are going into power changing device. The advantage of this method is the low cost of implementation because it uses embedded computer systems and does not require additional sensors for measuring temperature and insolation. It is very easy to upgrade in the case of increasing the knowledge base used in FIS membership function. Everything is simulated by MATLAB/Simulink software on the one-phase IBC system.
