On-grid PV Opportunities in University Campuses: A case study at Nazarbayev U...Luis Ram Rojas-Sol
The universities around the world are taking every day a more decisive role in fighting global warming. Indeed,
many campuses are not only teaching established and disrupting clean energy technologies, but also are practicing
their lectures. For example, the University of Arizona, USA, leads the campuses with 28 MW of installed On-Grid
PV systems (http://www.aashe.org/resources/campus-solar-photovoltaic-installations/top10/). Furthermore,
campuses of emerging universities, as Nazarbayev University (NU), located in Astana, Kazakhstan, which is
developing with the firm aim to become a leader world class research university in the heart of Eurasia, are taking
this commitment as well. Additionally, being Kazakhstan the host of EXPO-2017 which has the motto: ¨Future
Energy¨, it is natural to evaluate if NU campus would be a good candidate to support and exhibit, with demonstrated
technical and economic advantages, its own On-Grid PV in-campus system. Therefore, in this investigation, a
feasibility study of installing PV panels on the rooftop of School of Engineering at NU is carried out. A 24 kWp rooftop
PV installation with a 14.7% capacity factor, capable to export 31 MWh of electricity to the grid per year, is assumed
to be the system for the purpose of this analysis. The financial analysis has a horizon of 20-year lifetime and 25%
debt ratio financed at 15% interest over 20 years. Selection of appropriate equipment and calculation of financial
outcomes under three different scenarios or policy options are presented. The policies or scenarios corresponded
to having or not government grants (GG) and having attractive Feed-in-Tariff (FIT) rates in order to determine their
financial benefits. The GG scenario was stretched up to consider 30% of the total project cost and FIT was varied
from current offered FIT rate by KEGOC (Kazakhstan utility company) of 36,410 KZT/MWh to a more attractive rate
of 70,000 KZT/MWh. Results demonstrate that current scenario of FIT is marginally favorable (IRR on Equity: 15.1%,
Benefit-Cost Ratio: 1.37, Equity Payback: 8.8 years), while the 30% of incentives on top of current FIT moderatedly
improves the benefits of the project (IRR on Equity: 20.9%, Benefit-Cost Ratio: 1.47, Equity Payback: 7.2 years).
Nevertheless, upgrading current FIT to 70,000 KZT/MWh, even without incentives, proved to be enough to
dramatically improve the outcome of the project for investors (IRR-Equity > 28%, Equity Payback of 5 years and
Benefit-Cost ratio > 3.6), demonstrating that with a subtle change in policies, Nazarbayev University as many other
campuses in the country, may easily justify the investment in their On-Grid PV systems and therefore, become part
of the “green” universities in the world with direct contribution to tackle climate change.

“MODELING AND ANALYSIS OF DC-DC CONVERTER FOR RENEWABLE ENERGY SYSTEM” Final...8381801685
This project portrays a comparative analysis of DC-DC Converters for Renewable Energy System. The electrolysis method which increases the hydrogen production and storage rate from wind-PV systems. It has been proved that DC-DC converter with transformer has the desirable features for electrolyser application. The converter operates in lagging PF mode for a very wide change in load and supply voltage variations, thus ensuring ZVS for all the primary switches. The peak current through the switches decreases with load current.This paper portrays a comparative analysis of DC-DC Converters for Renewable Energy System . The simulation and experimental results show that the power gain obtained by this method clearly increases the hydrogen production and storage rate from wind-PV systems. It has been proved that DC-DC converter with transformer has the desirable features for electrolyser application. Theoretical predictions of the selected configuration have been compared with the MATLAB simulation results. The simulation and experimental results indicate that the output of the inverter is nearly sinusoidal. The output of rectifier is pure DC due to the presence of LC filter at the output. It can be seen that the efficiency of DC-DC converter with transformer is 15% higher than the converter without transformer.
Fuzzy optimization strategy of the maximum power point tracking for a variab...IJECEIAES
Wind power systems are gaining more and more interests; in order to diminish dependence on fossil fuels. In this paper, we present a variable speed-wind energy global system based on a synchronous generator with permanent magnetic (PMSG). The major goal of this study is to track the maximum power that is present in the turbine. An examination of control methods to extract the MPPT point, from a wind energy conversion system (WECS) under variable speed situations is presented. An intelligent controller based on the fuzzy logic control (FLC) is proposed for regulating permanent magnetic synchronous generator (PMSG) output power, in order to improve tracking performance. The principle of this maximum power point tracking (MPPT) algorithm consists in looking for an optimal operating relation of the maximum power, then tracking this last. We simulated our system with MATLAB-Simulink software. The found results will be debated to elucidate performance of the global system.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

41. Conclusions
The following conclusions are reported based on simulation and experimental studies,
• The experimental observation of the 3MW SPV plant during Mar 2014 to Feb 2015
indicated performance ratio to have varied between 58% to 87%.
• The Array conversion efficiency of the PV panel was observed to be varying between 9%
to 15% depending upon climatic conditions at the site.
• The PCU efficiency was observed to be close to 96% but lower than the rated value of
98% as per the manufacturer specifications.
• The rated capacity of SPV solar power plant was 3MWp, but the observed peak power
at the location is limited between 2.6-2.7 MW during the observation period.
• The simulation tools used in the reported work that included METEONORM,
HELIOSCOPE and PVSYST provided an efficient Graphical User Interface making it user
friendly.
• The power generation depended on solar irradiance, module temperature and also
some extent on wind flow. Increase in irradiance increased module temperature and
generation.
• Using statistical methods consisting of Mean Bias error, Root mean square error and
Mean percentage error shows result after comparison all values shows positive results
means they overestimated in result.

42. Scope for Future Work
• Studies on Earth-tester to measure leakage current and
isolation resistance of generator
• Studies on thermal imaging to detect abnormal heating in
solar modules, DC junction Boxes and Inverters.
• Studies on power quality analyzer or digital wattmeter can
be taken up to measure accurate power at Inverter side.
