Optimal power flow (OPF) in a hybrid alternating current and multi-terminal high-voltage direct current (AC-MTHVDC) grid is currently one of the most popular optimization problems in modern power systems.
16 Αυγ 2024 · The introduction of hybrid alternating current (AC)/direct current (DC) distribution networks led to several developments in smart grid and decentralized power system technology. The paper concentrates on several topics related to the operation of hybrid AC/DC networks.
1 Ιουλ 2020 · This paper studies an AC/DC hybrid system integrated with multiport solid-state transformers (SSTs) and distributed renewable energy and proposes an optimal configuration model for the AC/DC hybrid system based on a coordinate operation strategy of SSTs and energy storage.
comparison between AC and AC/DC distribution systems costs. The proposed methodology determines the optimal AC/DC distribution substation location and size and AC/DC feeder routing, as well as length and capacity of AC/DC feeders in both low-voltage and medium-voltage sides.
20 Οκτ 2020 · A hybrid AC/DC transmission system contains generically AC transmission assets, DC transmission assets, converters between those two types and potentially also converters for connecting asynchronous generation to one of the two transmission infrastructures.
