Design and Modeling of a PV Plant Connected to the Network for the Company Timab-Tunise

The company “Timab Tunisie” wishes to set up a PV central with a power of 1 MW connected to the network. The objective is to compensate for its energy needs in terms of electricity. This central will make it possible to save primary energy about 465.43 toe/year and reduce interrupted CO2 emissions by around 1108 tCO2/year. The work presented in this article aims at the design and modeling of the PV generator. PV central is equipped with five independently controlled static converters. Digital MPPT controllers integrated in the inverters ensure the search for maximum power delivered. After the description of the structure of the system, we present the simulation results for different climatic conditions as well as an estimate of the annual energy production.
