Multi-time scale coordination of complementary resources for the provision of ancillary services

Colin Neil Jones, Christophe Salzmann, Tomasz Tadeusz Gorecki, Faran Ahmed Qureshi, Luca Fabietti

This paper presents a predictive control scheme for coordinating a set of heterogeneous and complementary resources at different time scales for the provision of ancillary services. In particular, we combine building thermodynamics (slow), and energy stora ...

Stable and Passive High-Power Dual Active Bridge Converters Interfacing MVDC Grids

Drazen Dujic, Francisco Daniel Freijedo Fernández, Enrique Rodriguez Diaz

Dual active bridge (DAB) is a topology that is receiving more and more attention as a potential solution to interface dc grids of different voltage levels. From a system level, the implications of DABs on the stability of complex power systems are addresse ...

High Power Electronics Innovation Perspectives for Pumped Storage Power Plants

Drazen Dujic, Pedro Camilo de Oliveira e Silva, Miodrag Basic

The current framework of high penetration of intermittent energy sources requires variable-speed pumped hydro storage power plants (PHSPs) to provide grid support functions, which are, in this case, achieved through two technologies: doubly-fed induction m ...
