Micro-grid Technology, Research and Demonstration

This Sino-Danish project deals with research, development and demonstration of full-scale microgrid.  The work will be carried out by two highly rated Universities, Aalborg University (Denmrak) and Tsinghua University (China), also in cooperation with the companies Kamstrup A/S and Shanghai Solar Energy Science & Technology Co. Ltd.
The objective of this project is to develop a demonstrative, research-oriented platform, which aims to ease the integration of Distributed Generation units, hierarchical and multilevel control strategies, and multiple Microgrid configurations with the help of standard-based communication technology, resulting in a set of complete microgrid solutions. A microgrid is an electrical local distribution network which consists of DG units, energy storage systems and local loads that can operate in grid-connected or in islanded mode. The microgrid may be regulated by using a hierarchical control structure split in two levels: local and central controllers with the objective to locally and globally optimize the performance of each node and the microgrid, in order to provide satisfactory power quality, efficiency and demand response feature. Further, communication networks are needed in order to coordinate microgrid elements and a microgrid central controller can be used to acquire main system variables and to optimize the microgrid operation.
