A Review in a Single-Stage Inverter Design for a PV Micro-grid Integration in Sudanese National Grid

Integration of renewable energy sources in the national grid is a promising approach of solving grid problems such as power losses and shortage of supply in Sudan. The implementation of Photovoltaic (PV) power plants is expected to cover a wide range of rural areas and developing regions in Sudan in the upcoming years. This paper will serve as an introduction towards localizing the inverters industry in Sudan, both in terms of design and manufacturing. This shall be done by reviewing the inverters designs in order to find a suitable design that can be implemented in Sudan. Then, the paper will discuss the challenges and opportunities of localizing medium voltage inverters industry in Sudan. The project's results are expected to contribute towards manufacturing low-cost and high quality electric inverters in Sudan, which will reflect in the seamless integration of the PV stations as well as increase the efficiency and reliability, and elevate total power capacity of the grid.
