Klop, Casper L. (author), Dong, J. (author), Olsen, Pål Keim (author)The ModHVDC concept is a modular permanent magnet generator which uses insulated stator segments with dedicated power electronic converters to produce HVDC. This could significantly reduce the number of required power conversion steps for HVDC-connected offshore wind parks. However, the concept poses structural challenges to the machine design,...conference paper 2023

Gonzalez Silva, J. (author), Ferrari, Riccardo M.G. (author), van Wingerden, J.W. (author)Wind turbine (WT) controllers are often geared towards maximum power extraction, while suitable operating constraints should be guaranteed such that WT components are protected from failures. Control strategies can be also devised to reduce the generated power, for instance to track a power reference provided by the grid operator. They are...conference paper 2022

Scarabaggio, P. (author), Grammatico, S. (author), Carli, Raffaele (author), Dotoli, Mariagrazia (author)In this article, we propose a distributed demand-side management (DSM) approach for smart grids taking into account uncertainty in wind power forecasting. The smart grid model comprehends traditional users as well as active users (prosumers). Through a rolling-horizon approach, prosumers participate in a DSM program, aiming at minimizing...journal article 2022
