Hybrid power generation by and solar –windUday Wankar
With the development of industry and
agriculture, a great amount of energy such as coal, oil
and gas has been consumed in the world. Extensive
use of these fossil energies deteriorates a series of
problems like energy crisis, environmental pollution
and so on. Everybody knows that the fossil energy
reserves are finite, some day it will be exhausted.
It is possible that the world will face a
global energy crisis due to a decline in the
availability of cheap oil and recommendations to a
decreasing dependency on fossil fuel. This has led to
increasing interest in alternate power/fuel research
such as fuel cell technology, hydrogen fuel, biodiesel,
Karrick process, solar energy, geothermal energy,
tidal energy and wind. Today, solar energy and wind
energy have significantly alternated fossil fuel with
big ecological problems.
With the development of the science and
technology, power generation using solar energy and
wind power is gradually known by more and more
people. And it is widespread used in many developed
countries. The merits of the solar and wind power
generation are very obvious-infinite and nonpolluting.
The raw materials of the solar and wind
power generation derived from nature, and wind
power generation can work twenty-four hours a day,
solar power generation only works by daylight. In
addition, this kind of power generation has no
exhaust emission and there is no influence to the
nature. But it also has some shortcomings. Because
of the imperfect of the technology, equipment of the
solar and wind power generation is very expensive.
By far, it cannot be widely used.
In addition, solar and wind power
generation system affected by the changing of the
weather very much, so it has obvious defects in
reliability compared with fossil fuel, and it is difficult
to make it fit for practical use the lack of economical
efficiency .Because of these problems it needs to
increase the reliability of energy supply by
developing a system which interacts Solar and wind
energy. This kind of system is usually called windsolar
hybrid power generation system significantly

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
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).

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

9. Wind turbine
The wind turbine is playing a cardinal role in the entire system as it is
responsible for the generation of mechanical power needed to drive the
generator.
The primary factors on which the wind turbine performance depend are:
Wind speed
Direction of wind
Blade size
Pitch angle
Mechanical gears involved in its design
10. Mathematical model of wind turbine
The wind turbine can be represented in terms of a mathematical equation,
which governs its generated power.
Pm=mechanical output power of the turbine
Cp=D the air density [kg/m3],
cp the performance coefficient or power coefficient,
λ the tip speed ratio vt/vw, ( the ratio
between the blade tip speed vt and the wind speed
upstream the rotor vw [m/s])
Ѳ the blade pitch angle [deg], and
Ar the area swept by the rotor [m2].
11. Simulink Model For Wind turbine
Wind turbine extracts portion of wind turbine and converts it into
mechanical Power.
It has three inputs
Generator Speed
The Blade Pitch Angle
Wind speed.
One Output
Torque
12. Generator
The prime mover rotor of the (PMSG) is driven by Wind turbine mechanical
Power.
We have selected PMSG (5kW) because for small scale level PMSG is
considered as best type of generator.
better reliability, less maintenance and
more effective
No external dc excitation is needed.
Less losses and improved efficiency
13. The mechanical power of wind turbine provide torque to the
generator shaft.
The output generated by PMSG is variable in magnitude and
Frequency because of the fluctuating wind speed.
The output of the generator is fed
via stator into the rectifier block to
convert it into dc and smoothen it
14. Rectifier and controlled boost
Converter
For controlling the Ac output to a constant magnitude and frequency .
Convert the AC (Variable Frequency and Voltage) from generator to a DC
using Rectifier.
The boost converter then converts the DC rectified value into a constant
DC value
15. Inverter
Finally the inverter is used to convert the constant dc Voltage into Ac with
Constant frequency and Voltage Magnitude
16. PM DC Induction Generator
(Advantages and Disadvantages)
Don't require external excitation => Less power dissipation.
Space is not needed for windings => smaller
machine size (30% reduction in weight) and some cases cheaper.
Smooth stator structure unlike their salient pole structure in
conventional dc machines.
Power ratings ranging from few watts to 100kW or more.
Risk of demagnetization due to excessive currents in the motor
windings or due to overheating the magnet.
Limited air gap flux density that permanent magnets can produce.
17. Squirrel Cage Induction Generator
a. A wire loop in a nonuniform
magnetic field.
b. Several wire loops in a
nonuniform magnetic field.
c. Squirrel cage configuration, for
a squirrel-cage motor.
18. Squirrel Cage Induction Generator
Stator of the SCIG is connected to grid through back to back power
electronic converter bridges
Advantages
To make best use of wind energy available
No need of capacitor bank
Disadvantage
Expensive
19. Wound Rotor Induction Generator
Power Convertor size reduced by using it on rotor side of
WRIG
This is variable speed system using a wound rotor generator
The power converter is now connected between the rotor
and grid , so it needs to carry only the slip power.
20. WRIG
Advantages and Disadvantages
For utility scale wind power generation it outweighs
squirrel cage machine.
Offers a lot of flexibility for wide range of speed control
Used in high power applications in which a large
amount of slip power could be recovered
Speed of WRIM was changed by mechanically varying
external rotor circuit resistance(simplest way)
Major disadvantage is low efficiency due to additional
loses in resistor connected in the rotor circuit.
21. DOUBLY FED
INDUCTION
GENERATOR
Two power converter bridges connected back-to-back by means of a dc
link can accommodate the bidirectional rotor power flow in a DFIG.
The purpose of the grid side converter is to maintain the dc link voltage
constant.
It has control over the active and reactive power transfer between the
rotor and the grid.
The rotor side converter is responsible for control of the flux, and thus, the
stator active and reactive powers .
22. ADVANTAGES AND DISADVANTAGES
Operation at variable rotor speed while the amplitude and frequency of
the generated voltages remain constant.
Optimization of the amount of power generated as a function of the wind
available up to the nominal output power of the wind turbine generator.
Virtual elimination of sudden variations in the rotor torque and generator
output power.
Generation of electrical power at lower wind speeds.
Control of the power factor (e.g., in order to maintain the power factor at
unity).
Complicated
Maintainence
24. ADVANTAGES
Increase machine efficiency beyond 99%, reducing losses by as much as
50% over conventional generators
Energy savings
Reduced pollution per unit of energy produced
Lower life-cycle costs
Enhanced grid stability
Reduced capital cost
Reduced installation expenses
