Exponential Weighting Model Predictive Control with Observer for Modular Multilevel Converters
Sunny Singh, Saurabh Mishra, Dušan M Stipanović +1
In this article, we propose a model predictive control (MPC) scheme with an exponential cost function, along with an observer for the Modular Multilevel Converter (MMC), to enhance…
Robust Tuning of Model Predictive Control for MMC-Based High-Voltage Power Systems
Victor Daniel Reyes Dreke, Rahul Rane, Aleksandra Lekić
High-voltage direct current (HDVC) transmission systems based on modular multilevel converters (MMCs) have become a key topology in modern power systems. The dynamics of MMCs exhib…
Robust Current Regulation of MMC-based MTDC Power Systems based on Lyapunov Inequality
Victor Daniel Reyes Dreke, Rahul Rane, Aleksandra Lekić
Multi-terminal DC (MTDC) transmission systems based on modular multilevel converters (MMCs) are a key component of the envisioned future energy sector, where sustainability and eff…
Leveraging Optimal Information-Power Flow for Transmission Switching in AC/MTDC Grids
Haixiao Li, Aleksandra Lekić
The emerging AC/multi-terminal DC grids are regarded as a promising solution for accommodating the increasing integration of renewable energy sources. This work proposes an optimiz…
Advanced simulation framework for AC/MTDC power systems
Aleksandra Lekić, Azadeh Kermansaravi, Haixiao Li +3
Alternating current (AC)/multi-terminal direct current (MTDC) hybrid power systems (HPSs) play a crucial role in enabling long-distance power transmission and flexible interconnect…
SOPF-Based Adaptive Droop Control for Hybrid AC--HVDC Grids Under Offshore Wind Uncertainty
Hongjin Du, Aleksandra Lekić
The integration of massive offshore wind into hybrid AC-HVDC grids demands robust DC voltage regulation, yet conventional fixed-gain droop controllers struggle under severe stochas…
