Multilevel converter for direct grid integration of renewable energy system

Electrical energy generation from renewable energy sources such as the sun, wind etc., are widely adopted due to increase in electricity consumption. Development of renewable energy usage in towns and villages areas is an important factor and also its integration with the grid. The integration of renewable energy sources to grid with high efficiency is possible and also difficulty in transmission and distribution of power in towns & villages can be resolved with this paper. This paper discusses the multilevel converter practice for renewable power supply usage in towns & villages areas especially for hilly areas or where electrical supply is not available for domestic and industry use. With this paper, it is also possible to integrate with grid supply. Day to day, industrial electrical supply usage increases rapidly so the development of town energy source to meet an increase in demand of power is necessary. The aim of this paper is to group and review these recent contributions, in order to establish the current state of the art and trends of the technology, recently as a very important alternative in the area of control technology. Applications powered by multilevel converters and how multilevel converters are becoming an enabling technology in many industrial sectors and towns & villages areas.
