Distributed Optimization in Distribution Systems with Grid-Forming and Grid-Supporting Inverters
2022 IEEE Power & Energy Society General Meeting (PESGM), 2022 With massive penetrations of active grid-edge technologies, distributed computing and optimization paradigm has gained significant attention to solve distribution-level optimal power flow (OPF) problems. However, the application of generic distributed optimization techniques to OPF problems leads to a very large number of macro-iterations or ...

Transient Safety Filter Design for Grid-Forming Inverters [PDF]
2020 American Control Conference (ACC), 2020 Unlike conventional generators, inverter-based generation do not possess any rotational inertia. While grid-forming inverters can synthesize small (virtual) inertia via advanced feedback control loops, additional control mechanisms are needed to ensure safety and security of the power grid during transients.

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 ...

An MPC Approach for Grid-Forming Inverters: Theory and Experiment [PDF]
Energies, 2020 Microgrids (MGs) interest is growing very fast due to the environment urgency and their capability to integrate renewable energy in a flexible way. In particular, islanded MGs in which distributed energy resources (DERs) are connected to the infrastructure with power electronic converters have attracted the interest of many researchers of both academia

Grid-Forming Inverter with Simplified Virtual Synchronous Compensator Providing Grid Services and Grid Support [PDF]
, 2021 This paper proposes a Simplified Virtual Synchronous Compensator (S-VSC) model with grid-forming capabilities for microgrid applications. Previous works have shown how the S-VSC can provide grid services (i.e., virtual inertia, current harmonic ...

FEBS Letters, EarlyView.Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.
