modeling a photovoltaic base connected to network along with using boost convertor and MPPT method and photovoltaic system design

Solar energy is the greatest energy resources in the world. This energy is clean, free and endless and it is exploitable in many parts of the world. Limited fossil resources and the consequences of environmental changes and global climate create opportunities to compete the solar energy with fossil fuel especially in the countries with high radiation. With regard to the issue that Iran is deprived of rain in 8 to 9 months of the year and in fact, it has clear sky, therefore, RLS algorithm which is used to determine parameters of the system as on line has applied to estimate the parameters of the system that system under its control can use in wide range. In continue the relationships of this algorithm are used to estimate Chart voltage - power photovoltaic. The relationships of voltage and cells inset solar CIS are estimated with polynomial forth degree with regard to the source 2. Based on this and in this relationship, the estimation error has been defined and it has given into the fuzzy controller. Finally, the result of simulation showed that the performance of this method has more suitable performance to compare with fuzzy controller. Following the modeling of a photovoltaic power plant connected to the network along with the boost converter and MPPT method and inverter to connect to the network were seen. Finally, the results related to simulation of this power plant presented in PSIM software
