Research on Reactive Power Coordination Control of Urban Rail Transit Power Monitoring System

Chengshi guidao jiaotong yanjiu
[Objective] The power supply system of urban rail transit mainly relies on the SVG (static var generator) or reactors in the 110 kV main substation for centralized reactive power compensation. The current control mode does not fully consider the reactive

Efficient State Estimation in Power Networks for Reactive Power Losses Compensation [PDF]

, 2013
We consider the problem of optimal reactive power compensation for the minimization of power distribution losses in a smart microgrid with raw measurements. We provide two distributed estimation algorithms, one ADMM-based and one JACOBI-like, in order to

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

FEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...
