Stable Power Electronic-based Power Grids



With the increasing use of power electronic interfaced renewable energy (RE) generations (e.g. PV, wind power), high voltage direct current transmission (HVDC) system and new types of power electronic connected loads (e.g. Electrical vehicles), more and more power electronics are connected to power grids. Consequently, the characteristics of a power grid is largely affected by the connected power electronics and their control, e.g. lower inertia, smaller short circuit capacity, etc. The large-scale integration of power electronics into power grids is bringing new challenges to the security and stability of power grids, these challenges are substantially significant in both Denmark and China, the former has the highest wind power penetration ratio and the latter has the largest wind turbine installed capacity in the world. In this background, the project, named Stable Power Electronic-based Power Grids (SPEG), aims to initiate a new network and establish the collaboration between Department of Energy Technology, Aalborg University (ET-AAU), Denmark and Tsinghua-Berkeley Shenzhen Institute (TBSI), China to start the comprehensive studies in the research area of the power electronic-based power grids to address these challenges. The project has the following scientific focus: 1) modelling the power grids with large scale renewable energy and power electronics, 2) investigating the impacts of high penetration of renewable energy and power electronics on power grids, 3) developing control strategies for improving the stability of the power electronic-based power grids.
