The original simulation verified the fuel‐saving effect of the energy storage system for adjusting the load factor of generators to optimal conditions. Through the analysis of the simulation results, it was revealed that the energy storage system showed the potential to save the fuel consumption of generators by more than 600 l in 7 days under certain ...

A Hybrid Ultra‐High Voltage DC Transformer With Digital Twin‐Driven Operation and Control
This study introduces a digital twin‐driven hybrid ultra‐high‐voltage DC transformer (UHVDCT) that combines high‐capacity LCCs with low‐capacity MMCs at the UHV side. This innovative topology reduces MMC requirements by 32.9% while ensuring stable power flow and dynamic reactive balance through real‐time virtual‐physical synchronization.

This paper proposes a hybrid sensorless control strategy for a permanent magnet synchronous generator (PMSG)‐based wind energy conversion system (WECS). The approach integrates finite‐set predictive current control (FS‐PCC), a model reference adaptive system (MRAS) estimator and an optimal torque control maximum power point tracking (MPPT‐OTC) method ...
