Topology Optimization for DC Circuit Breaker Placement in HVDC Switching Stations
Merijn Van Deyck, Tom Van Acker, Geraint Chaffey +1
HVDC protection will be required in future multiterminal HVDC grids to prevent large outages caused by DC faults. Therefore, system-level protection design is essential for the dev…
Hybrid Analytical--EMT Method for HVDC Protection System Component-Level Design
Abolfazl Mohammadi, Merijn Van Deyck, Geraint Chaffey +1
Protection system design for multi-terminal HVDC grids is challenging due to the complexity of the system and the often conflicting design requirements. Effective specification of…
Fairness for distribution network operations and planning
Pedro F. C. de Carvalho, Zijie Liu, Md Umar Hashmi +1
The incorporation of fairness into the distribution network (DN) planning and operation has become a key goal of recent studies. The cost of implementing fairness, denominated the…
Coordinated Dynamic Operating Envelopes for Network-Admissible Flexibility at the Grid Edge
Ali Jalilian, Deepjyoti Deka, Md. Umar Hashmi +1
Dynamic operating envelopes (DOEs) provide a systematic framework to integrate the flexibility of distribution grid resources while safeguarding network limits such as line ratings…
Importance of Aggregated DER Installed Capacity in Distribution Networks
Alexandre M. V. Gouveia, Md. Umar Hashmi, Reinhilde D'hulst +1
The increasing penetration of Distributed Energy Resources (DERs), particularly electric vehicles, heat pumps, and photovoltaic systems, is fundamentally changing power flows in Lo…
Identifying Best Candidates for Busbar Splitting
Giacomo Bastianel, Dirk Van Hertem, Hakan Ergun +1
Rising electricity demand and the growing integration of renewables are intensifying congestion in transmission grids. Grid topology optimization through busbar splitting (BuS) and…
