Abstract
Nowadays worldwide, distributed generation plays a more and more important role in world's energy supply system. But distributed resources' innate weaknesses cause some problems such as wavy output power and instability of power generation. These innate weaknesses are hard to overcome only through improving one single distributed generation plant or adding energy storage equipment etc. In this article, a new concept of connecting several AC distributed generation plants (such as wind farm) via VSC-converter, and DC distributed generation plants (such as solar cell) via DC/DC converter and forming a low voltage DC network is given. This low DC network will be integrated into AC grid in some proper way. Namely equalize these small distributed generation plants to a big power generation farm to improve stability of electricity generation. Some simulations based on PSCAD/EMTDC are also given.Keywords
