Abstract: Premium power park (PPP) is the important application aspect of custom power technology. In this paper, the power supply and power quality devices (PQDs) are mainly analyzed from such aspects as application cases and research situation of PPP. Firstly, the coordination in two typical PPP application cases is discussed. Then the coordination problems of PPP are introduced to realize power supply in different power quality levels and to improve the reliability of whole power supply, and a coordination flow chart is proposed. In the end, how to coordinate the power supply and PQDs is pointed out for future construction and research of PPP.
