Coordinated frequency control through MTDC transmission systems
(2015)IFAC-PapersOnLine ~ 5th IFAC Workshop on Distributed Estimation and Control in Networked Systems, NecSys 2015. ProceedingsIn this paper we propose a distributed dynamic controller for sharing frequency control reserves of asynchronous AC systems connected through a multi-terminal HVDC (MTDC) grid. We derive sufficient stability conditions, which guarantee that the frequencies of the AC systems converge to the nominal frequency. Simultaneously, the global quadratic cost of power generation is minimized, resulting in an optimal distribution of generation control ...Conference Paper -

Voltage Dependent Pricing in DC Distribution Grids
(2013)2013 IEEE Grenoble ConferenceA dominance of fluctuating renewable energy resources requires changes in the electric power system. The introduction of nodal variable prices to balance supply and demand is one option that requires the price to be known to all devices. In this paper a new method to determine the price based on the local nodal voltage is introduced. As more and more devices use direct current (DC) internally, the advantages of DC distribution grids are ...Conference Paper
