ABSTRACT
Renewable energy-based power plants are increasingly used to fulfill the rapidly increasing electrical load demand because renewable energy plants are clean, eco-friendly, and environmentally sustainable. They also require less time for plant installation compared to traditional fossil fuel-based power plants. Power converters play an important role in the grid integration of renewable energy sources. The traditional low-voltage power converter utilizes a power frequency transformer and a line filter to integrate the renewable energy sources with the power grid, but they are heavy and bulky. Recently, medium-voltage power converters that do not require power frequency transformers and line filters are becoming increasingly popular. This chapter aims to review different power converter topologies with different switching and control strategies for the grid integration of renewable energy sources. The chapter also presents current research activities and possible future directions for the power converter topologies in a grid-connected renewable energy power conversion system.
