Control of Wind Farm Power Output for Green Hydrogen Production without a Grid Connection

Subject: Engineering, Energy And Fuel Technology Keywords: wind farm control; green hydrogen; electrolysis; battery lifetime; wind turbine control

Green hydrogen is likely to play an important role in meeting the net zero targets of countries around the globe. Hence, producing green hydrogen cheaply and effectively is an important area of research. One potential option for green hydrogen production is to run electrolysers directly from offshore wind turbines, with no grid connection and hence no expensive cabling to shore. The removal of the grid presents an unusual integration challenge. The variable nature of wind turbines and farms results in a power output that can fluctuate more quickly than the electrolyser’s ability to respond without significantly stressing the electrolyser. Thus, the use of a battery, with the wind farm, becomes essential to even out some of the power variations that the electrolyser cannot deal with. In this work, a proof of concept of a wind farm control methodology designed to reduce variability in wind farm active power output is presented. Smoothing the power supplied by the wind farm to the battery reduces the size and number of battery charge cycles and helps to increase battery lifetime. Considering off-grid wind farms which exclusively power an electrolyser, this work quantifies the impact of the wind farm control method on battery lifetime for wind farms of 1, 4, 9 and 16 wind turbines. This is achieved using suitable wind farm, battery and electrolyser models. As an example, for the largest wind farm studied, consisting of 16 x 5 MW wind turbines, batteries with a lifetime of 15 years have approximately a 30 % reduction in required capacity (reduced from 14 MWh to 10 MWh) compared to operating without wind farm control. It is found that reducing the variability of the active power output of wind farms through the wind farm control methodology presented can have a significant impact on battery degradation and hence on battery lifetime. Hence, wind farm control can reduce the required battery capacity for a given lifetime or it can increase the lifetime of a given battery capacity. The work presented shows that wind farm control could play a critical role in reducing the levelised cost of green hydrogen produced from wind farms with no grid connection and paves the way for the design and testing of a full implementation of the wind farm control.

This study aimed to examine the locus of control and epistemological beliefs of social 12 studies teacher candidates. The research, which adopted a survey model, was conducted with 550 13 social studies teacher candidates studying at 7 state universities in Turkey. The Locus of Control 14 Scale and the Epistemological Belief Scale were used to collect research data. Descriptive statistics, 15 independent samples t-test, one-way analysis of variance (ANOVA), Scheffe test, and correlation 16 analysis were employed in the data analysis process. When evaluating the research results, it was 17 determined that the teacher candidates generally responded to the locus of control scale at an “ap-18 propriate” level and to the epistemological belief scale at an “agree" level.” While no significant 19 difference was observed in the locus of control beliefs of social studies teacher candidates based on 20 gender, a significant difference was found in the sub-scale of belief in an unjust world. It has been 21 determined that female teacher candidates have a higher external locus of control belief. No signif-22 icant difference was observed in social studies teacher candidates’ locus of control beliefs regarding 23 their parents’ educational levels and grade level. However, there was a significant difference in the 24 sub-scale of belief in an unjust world regarding grade level. It was observed that there was a signif-25 icant difference in the epistemological beliefs of social studies teacher candidates regarding gender. 26 It was revealed that female teacher candidates had underdeveloped /immature epistemological be-27 liefs. No significant difference was found in the epistemological beliefs of teacher candidates based 28 on their parents’ educational levels or grade level. It has been observed that there is a weak but 29 positive significant relationship between the social studies teacher candidates’ locus of control and 30 epistemological beliefs and their sub-scales.

This study evaluates the efficacy of the salts, sodium metabisulfite (SMB), ammonium bicarbonate, sodium bicarbonate and potassium dihydrogen orthophosphate first in vitro against the main postharvest fruit rot fungi, Alternaria alternata, Botrytis cinerea, Penicillium italicum and Penicillium digitatum. Results showed that 0.2% SMB completely inhibited mycelium growth of the fungal species. Ammonium bicarbonate and sodium bicarbonate were less effective at 0.2% in inhibiting mycelial growth, ranging from 57.6% to 77.6%. The least effective was potassium dihydrogen or-thophosphate. Experiments were also performed in vivo on wounded apples inoculated with the most pathogenic fungus, B. cinerea, and treated with SMB at concentrations of 0.2, 0.5, 1, 2 and 3%, both preventively and curatively. Results based on the decay size showed that SMB, when used as a preventive treatment, had a reduced efficacy, even with the highest concentration. However, this salt proved to be very effective at 0.5% in curative treatment, since the decay was completely blocked. Our results suggest that the appropriate concentration of SMB for post-harvest treatment is 0.5% as a curative treatment. On the other hand, the 1% dose induced the onset of phytotoxicity around the wound. To assess the extent of phytotoxicity reaction, higher concentrations of 1-4% SMB were applied to wounded fruit. Apples and oranges were inoculated or not with B. cinerea and P. digitatum respectively. Doses of 1- 4% induced phytotoxicity in the form of a discoloured ring surrounding the wound on the epidermis of the fruit; this phytotoxicity enlarged as the concentration of SMB increased. The phytotoxic features were similar on apples and oranges. The methodological procedure made it possible to carry out a quantitative assess-ment of SMB phytotoxicity. This method is proposed as an easy-to-use technique for quantitatively estimating the phytotoxicity of antifungal compounds on post-harvest fruit.

Background Aspergillus spp. is a widely distributed filamentous fungus in the environment due to its high sporulation capacity. Currently, invasive aspergillosis (IA) is the most common invasive fungal infection in patients with hematologic malignancies with high rates of mortality and morbidity. The multifactorial nature of the disease requires appropriate risk stratification to allow the most appropriate preventive measures to be adapted and implemented according to the characteristics of the patient. In this sense, the present research aims to identify recent risk factors and environmental control measures against invasive aspergillosis to establish preventive actions to reduce the incidence of invasive aspergillosis in hospitals; (2) Methods: We conducted a qualitative systematic review of the scientific literature on environmental risk factors and preventive measures for invasive aspergillosis in patients with hematological malignancies. The Medline, Cochrane and Scopus databases were consulted, following the PRISMA and STROBE guidelines; (3) Results Adequate implementation of environmental control measures is presented as the most efficient intervention in terms of prevention to decrease the incidence of invasive aspergillosis in hospitals. We identify neutropenia, fungal contamination, lack of adequate environmental control measures in hospitals and patients´ homes, duration of hospitalization, and anemia as independent risk factors. We show that HEPA, LAF and Plasmair® systems are suitable methods to reduce the concentration of airborne fungal spores. Antifungal prophylaxis did not influence the reduction of IA significantly in our study; (4) Conclusions: Proper professional training and environmental control measures in hospitals are essential for the prevention of invasive aspergillosis. We should optimize risk stratification for patients with hematologic malignancies. Antifungal prophylaxis should be complementary to environmental control measures and should never be substituted for these last ones. Studies should also be done to evaluate the efficiency of environmental control measures against IA at patients' homes.
