Study on the application of advanced power electronics in smart grid

It is well known that the tendency of the smart grid constructing is more reliable, secure and efficient. Advancement in power electronics technology provides an important approach for such purpose. Therefore, this paper studied on the application of advanced power electronics in smart grid. The demand of a smart grid for advanced power electronics technology and the research and development trend of advanced power electronic technology was introduced firstly. Then the principle of power electronics technology and its applications in smart grid was presented, with emphasis on the application of FACTS (Flexible AC Transmission Systems) technology, HVDC (high voltage DC Direct Current) transmission system technology and power quality technology in smart grid. The security, efficiency and reliability of that smart grid, which had applied advanced power electronics were evaluated. The result shows that application of the advanced power electronic technology can strengthen and optimize the grid, ensure the safety of power grid stability and promote the utilization of renewable energy.
