With a higher wind power penetration level, the system is facing more challenges in aspects of active balance and frequency regulation. The reserve control enables farm (WF) to retain certain available as reserves, for participating regulation similarly synchronous generators. In this paper, coordinated method WF proposed. By using linear programming approach, proposed allocates each turbine ge...

HVDC can provide frequency regulation during disturbances (e.g., faults) by controlling the power flow between two remote AC areas. While this action reduces deviation in area affected disturbance, it causes a imbalance other healthy area, leading to variation and endangering system stability. In work, primary voltage-dependent loads (PFR-VDL) is proposed, where terminal influences grid voltage...

background suicidal attempt and non-suicidal self-injury are very common in adolescents with a history of childhood maltreatment. by identifying correlates of these kinds of high-risk behaviors, it is possible to prevent and decrease completed suicide. objectives the aims of this study were: 1) to compare adolescents with a history of childhood maltreatment with non-suicidal self injury (nssi) ...

This article presents an important finding: the parameters of secondary frequency control based on integral or proportional integral control can be tuned to achieve economic operation and frequency regulation simultaneously. We show that if the power imbalance is represented by frequency deviation, an iterative dual ascent based economic dispatch solving is equivalent to integral control. An it...

The purpose of this project was to identify whether dynamic baroreflex regulation of heart rate (HR) is altered during whole body heating. In 14 subjects, dynamic baroreflex regulation of HR was assessed using transfer function analysis. In normothermic and heat-stressed conditions, each subject breathed at a fixed rate (0. 25 Hz) while beat-by-beat HR and systolic blood pressure (SBP) were obt...

background: human leukocyte antigen-g (hla-g) is a non-classical class i molecule highly expressed by extravillous cytotrophoblast cells. due to a single base pair deletion, its function can be compensated by other isoforms. investigating the frequency of null allele in recurrent miscarriage (rm) subjects could be useful in understanding the relationship between frequency of this allele and rm ...
