Optimal Power Flow Analysis Based on Hybrid Gradient-Based Optimizer with Moth–Flame Optimization Algorithm Considering Optimal Placement and Sizing of FACTS/Wind Power

open access: yesMathematics, 2022
Optimal power flow (OPF) is one of the most significant electric power network control and management issues. Adding unreliable and intermittent renewable energy sources to the electrical grid increase and complicates the OPF issue, which calls for using

Design of a prototype D-STATCOM using DSP controller for voltage sag mitigation [PDF]

open access: yes, 2006
This paper presents the design of a prototype distribution static compensator (D-STATCOM) for load compensation in an unbalanced distribution system. The D-STATCOM is intended to replace the widely used static VAr compensator (SVC).

KDM7A and KDM1A inhibition suppresses tumour promoting pathways in prostate cancer

open access: yesMolecular Oncology, EarlyView.
Treatment resistance is a major challenge for patients with advanced prostate cancer. This study examined an alternative approach to target the major prostate cancer‐promoting pathway by targeting epigenetic factors, whose levels are higher in tumours.

dUTPase is essential in zebrafish development and possesses several single‐nucleotide variants with pronounced structural and functional consequences

open access: yesFEBS Open Bio, EarlyView.
dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...

Application of Static Var Compensator in Songhe Coal Mine

open access: yesGong-kuang zidonghua, 2010
In order to solve problems that traditional stationary reactive var compensator only compensates power factor to some extent and cannot eliminate higher harmonic pollution of power network caused by soft starters of high power loads of coal mine, the ...

A Voltage Control Method Considering the Collaborative Optimization of Multiple Reactive Power Compensation Devices

open access: yesZhongguo dianli, 2022
In order to deal with the steady-state and transient voltage fluctuation caused by power system disturbance, taking static var compensator (SVC), capacitor bank (CB), on load tap changer (OLTC) and synchronous condenser (SC) as comprehensive reactive ...

Balancing asymmetrical load using a static var compensator [PDF]

open access: yesIEEE PES Innovative Smart Grid Technologies, Europe, 2014
Power electronic controllers are employed in the transmission and distribution levels of the power systems. In transmission level applications, Flexible AC Transmission System (FACTS) controllers, consist of shunt and series static compensators, are applied for power flow control, stability enhancement, voltage regulation and power oscillation damping.

C2α‐carbanion‐protonating glutamate discloses tradeoffs between substrate accommodation and reaction rate in actinobacterial 2‐hydroxyacyl‐CoA lyase

open access: yesFEBS Open Bio, EarlyView.
Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,
