Local compensation in distribution network grids

At Aalborg University a project concerning local compensation of the distribution network was started in 1998. The main focus was to see how to employ and control custom power systems (CUPS) in the distribution network, to build a CUPS-device to clean out some of the disturbances and to see how the disturbances were transmitted through the network grid. The project was build up as three separate projects: design and control of a dynamic voltage restorer, employment and control of CUPS in the distribution network and broadband modelling of the distribution network. The main results from the projects are reported in this paper.
