Intelligent Techniques to Connect Renewable Energy Sources to the Grid: A review

Existing classical power grid systems are very sensitive against the integration of renewable and distributed energy sources due to voltage and frequency fluctuations that cause several problems like power outrage and blackouts. On the other hand, increasing the power capacity of the existing grid system as well connection of the renewable energy sources to the grid are unavoidable. So that, a smooth connection of renewable and distributed power system to the grid is required and many researchers have done several researches on this hot topic. Therefore, intelligent techniques to connect the renewable energy sources to the grid have been addressed in this study and recent researches in this field have been reviewed and some comments have been done for the researchers, young engineers, students, transmission system operators, distribution system operators as well as policy makers and end users.
