Payment analysis for a BESS providing dynamic frequency response in the Irish grid

The increased uptake of renewable energy generation has lead to a growing interest in grid-connected energy storage systems, such as batteries and flywheels, for maintaining grid stability. A number of countries have developed schemes for the provision of frequency response services, with some grid operators, such as National Grid in Great Britain and Eiregrid in Ireland, having a range of static and dynamic services. For the provision of dynamic services, the use of tighter frequency margins, which results in the unit providing frequency response more regularly and in higher volumes, may be incentivised through higher payments. One example of such a scheme is in Ireland under the Eiregrid DS3 programme, where a tariff system that incorporates both the performance and frequency margins of units providing dynamic response has been introduced. This paper examines how the choice of frequency margins affects overall payments for Battery Energy Storage Systems (BESS) operating in the Irish grid. Analysis is performed by simulating the BESS system using Irish grid frequency data. The results provide insights into how the frequency margins affect payments for different frequency response services, and show how payments to a BESS providing dynamic frequency response are maximised

Optical coherence tomography attenuation imaging for lipid core detection:an ex-vivo validation study

Lipid-core atherosclerotic plaques are associated with disease progression, procedural complications, and cardiac events. Coronary plaque lipid can be quantified in optical coherence tomography (OCT) pullbacks by measurement of lipid arcs and lipid lengths; parameters frequently used in clinical research, but labor intensive and subjective to analyse. In this study, we investigated the ability of quantitative attenuation, derived from intravascular OCT, to detect plaque lipid. Lipid cores are associated with a high attenuation coefficient. We compared the index of plaque attenuation (IPA), a local quantitative measure of attenuation, to the manually measured lipid score (arc and length) on OCT images, and to the plaque characterization ex-vivo. We confirmed a correlation between the IPA and lipid scores (r2 > 0.7). Comparison to histology shows that high attenuation is associated with fibroatheroma, but also with macrophage presence. IPA is a robust, reproducible, and user-independent measure that facilitates quantification of coronary lipid, a potential tool in clinical research and in guiding percutaneous coronary intervention

Xaf1 can cooperate with TNFα in the induction of apoptosis, independently of interaction with XIAP

XIAP-associated factor 1 (Xaf1) binds XIAP and re-localizes it to the nucleus, thus inhibiting XIAP activity and enhancing apoptosis [1]. Xaf1 expression is reduced or absent in tumor samples and cell lines suggesting it may function as a tumor suppressor [2–5]. To further study Xaf1 function we generated Xaf1 inducible cells in the osteosarcoma cell line Saos-2. Despite Xaf1 inducing apoptosis that is dramatically enhanced by TNFα we find no evidence for an interaction between Xaf1 and XIAP. Furthermore, Xaf1 expression sensitized XIAP −/− fibroblasts to TNFα, demonstrating the existence of a novel mechanism of Xaf1 induced apoptosis distinct from antagonizing XIAP. Xaf1 expression promotes cytochrome c release that cannot be blocked by inhibition of caspase activity. This implicates a role for the mitochondrial apoptotic pathway, consistent with the ability of Bcl2 to block Xaf1 induced apoptosis. The data indicate that in Saos2 cells Xaf1 activates the mitochondrial apoptotic pathway to facilitate cytochrome c release, thus amplifying apoptotic signals from death receptors.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/45342/1/11010_2005_Article_9094.pd

A comparison of extrapolation techniques for Model Predictive Direct Current Control

The use of output bounds and trajectory extension enables Model Predictive Direct Current Control (MPDCC) to achieve low current distortion for a given switching frequency, making it very well-suited to high-power applications where switching frequencies in the range of a few hundred Hz are typical. One of the main drawbacks of MPDCC, however, is the large computational requirement associated with model-based extension of the output current trajectories. In order to overcome this, approximate extension techniques must be used for practical implementation, making the analysis of such techniques very important. This paper addresses the existing gap in the literature by providing a comprehensive review of Linear (LE) and Quadratic (QE) extrapolation techniques for MPDCC. Using a MATLAB-based simulation of a grid-connected Neutral-Point-Clamped (NPC) converter as a case study, the relative performance of the different extrapolation techniques is evaluated using the trade-off between switching frequency and current distortion. The execution times of the various strategies are also provided using a TI TMS320F280049 microcontroller as an example control platform

Interaction of the Coffee Diterpenes Cafestol and 16-O-Methyl-Cafestol Palmitates with Serum Albumins

The main coffee diterpenes cafestol, kahweol, and 16-O-methylcafestol, present in the bean lipid fraction, are mostly esterified with fatty acids. They are believed to induce dyslipidaemia and hypercholesterolemia when taken with certain types of coffee brews. The study of their binding to serum albumins could help explain their interactions with biologically active xenobiotics. We investigated the interactions occurring between cafestol and 16-O-methylcafestol palmitates with Bovine Serum Albumin (BSA), Human Serum Albumin (HSA), and Fatty Free Human Serum Albumin (ffHSA) by means of circular dichroism and fluorimetry. Circular Dichroism (CD) revealed a slight change (up to 3%) in the secondary structure of fatty-free human albumin in the presence of the diterpene esters, suggesting that the aliphatic chain of the palmitate partly occupies one of the fatty acid sites of the protein. A warfarin displacement experiment was performed to identify the binding site, which is probably close but not coincident with Sudlow site I, as the affinity for warfarin is enhanced. Fluorescence quenching titrations revealed a complex behaviour, with Stern-Volmer constants in the order of 103-104 Lmol-1. A model of the HSA-warfarin-cafestol palmitate complex was obtained by docking, and the most favourable solution was found with the terpene palmitate chain inside the FA4 fatty acid site and the cafestol moiety fronting warfarin at the interface with site I
