Frequency Response of PV Inverters Toward High Renewable Penetrated Distribution Networks

open access: yes, 2022
Substantial usage of electronic-based renewable energy resources has completely changed the dynamic behaviours and response time of power networks, which are now fundamentally different from traditional power networks dominated by Synchronous Generators (

Optimal planning of renewable energy source and energy storage in a medium- and low-voltage distributed AC/DC system in China

open access: yesThe Journal of Engineering, 2019
As the quantity of DC load and distributed generation system increases in China, AC/DC distribution system is arousing more and more research interest for its high-efficiency distribution ability. In this study, the optimal size and location of renewable

Distributed connectivity of wireless networks [PDF]

open access: yesProceedings of the 2012 ACM symposium on Principles of distributed computing, 2012
We consider the problem of constructing a communication infrastructure from scratch, for a collection of identical wireless nodes. Combinatorially, this means a) finding a set of links that form a strongly connected spanning graph on a set of $n$ points in the plane, and b) scheduling it efficiently in the SINR model of interference.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

A multi‐power quality problems management strategy based on VSCs and switches in AC/DC hybrid LVDN with large PVs

open access: yesIET Renewable Power Generation
A large scale of distributed photovoltaics is accessed through a low voltage distribution network in a single‐phase or two‐phase, which causes three‐phase unbalance and over‐voltage problems.

A coordinated dispatch method for distribution and microgrid systems based on semidefinite programming relaxation

open access: yesZhejiang dianli
The widespread adoption of distributed energy resources (DER) has significantly increased the complexity of distribution networks. Coordination between distribution networks and microgrid(s) can facilitate the integration of distributed energy, but ...

Coordinated active and reactive power control for overvoltage mitigation in physical LV microgrids

open access: yesThe Journal of Engineering, 2019
The share of photovoltaic (PV) systems in the distribution networks is rapidly growing, leading to the common issue of overvoltage at the end of distribution feeders during the periods when peak generation is surplus to consumption.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

A Modelling Tool for Distribution Networks to Demonstrate Smart Grid Solutions

open access: yes, 2014
The increased deployment of low carbon technologies in power distribution networks, particularly at the distribution level, is expected to cause significant problems to network operation unless existing networks are appropriately adapted and actively ...
