DESIGN A MODIFIED PREDICTIVE CONTROLLER FOR ORGANIC PHOTO VOLTAIC IN OUTDOOR CONDITIONS

Abstract

The use of renewable resources such as solar arrays has many advantages, including reducing the consumption of fossil fuels and the emission of environmental pollutants, improving the level of grid stability and reducing power losses in transmission and distribution lines. On the other hand, increasing the penetration level, leads to significant changes in the level of low voltage distribution network, so that if not controlled properly, it may lead to the voltage exceeding the allowable range. For this purpose, it is necessary to adopt solutions to overcome these challenges. In this Thesis, combination of dynamic voltage restorer and MPC-based maximum power point tracking is used for controlling the level of voltage profile. In order to achieve practical results, the state of the voltage profile level for a part of the residential distribution network of Makkah city from Saudi Arabia has been investigated, and in this regard, MATLAB and DIgSILENT softwares have been used to perform simulations. The time step is equal to one hour and the results have been implemented in the form of three scenarios. According to the obtained results, by applying the mentioned control method, not only more than 7% of voltage range changes are reduced, but by reducing the level of voltage unbalance, the reliability and stability level of the network is also increased
