The wide adoption of a new type of electric trains results in multiple frequency-scale
instability problems, such as low-frequency oscillation (LFO), harmonic resonance, and …

Harmonic resonances in traction power supply systems (TPSSs) have attracted great
attention due to their potentially destructive impact on the safe and stable operation of …

Distributed energy resources (DER) and electrical loads have grown rapidly in response to
concerns about energy sustainability and rising energy demand. However, to realize energy …

This paper proposes an energy storage system (ESS) for recycling the regenerative braking
energy in the high-speed railway. In this case, a supercapacitor-based storage system is …

The widespread deployment of renewable energies and non-linear loads has led to serious
harmonic pollution in the electrical distribution networks. Evaluation of the harmonic …

Due to the growing demand for broadband impedance modeling and stability analysis of
renewable power generation equipment, extensive research has been conducted on …

With the rapid development of renewable energy resources, harmonics in modern
distribution systems have become more serious owing to the wide adoption of power …

Impedance measurement is an effective method to obtain the impedance characteristic of
renewable power generation equipment (RPGE) for stability analysis. Frequency-coupling …

As ac electric railways have various problems (eg, power quality issues, complex catenary
networks, limited supply region, and passing neutral section), the medium-voltage direct …

Both efficiency and operation cost are the key to offshore microgrids operation. At the same
time, due to the lack of external energy support, the paralleled converters in offshore …
