EFFECT OF HOT-SPOTTED CELL ON PV MODULE PERFORMANCEIAEME Publication
In this paper, the effects of the hot-spotted cell on PV module were evaluated. The
experimental observation was based on 100 kW PV array composed of 20 PV modules.
It was found that an increasing number of hot-spotted solar cells in a PV module would
likely increase its output power loss. It was also noticed that most of the PV modules
affected by hot-spotted PV string are relatively affected by high-temperature levels,
dust, and Partial shading due to trees or tall vegetation. Furthermore, the average
performance ratio (PR) and degradation rate (DR) of all examined PV modules were
analyzed. PR was observed to have a higher value of 0.78 in a non-hot-spotted PV array,
whereas low PR of 0.65 was observed in a hot-spotted PV array. High DR of 3.13/year
was observed in hot-spotted PV array; while low DR of 1.48/year was found in a module
with no hot-spot. It was evident that the mean PR is significantly reduced due to the
existence of hot-spots in the PV modules. DR was also increased due to hot-spot in the
PV array. Hence, it is important to select materials that have the highest thermal
stability to avoid mild hot spot situations that will lead to immediate damage of the
panel. Hot-spot study analysis will help increase PV lifetime power output by detecting
and preventing hot spotting before it permanently damages the PV panel.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

other sources of primary energy
There are various methods to generate electricity
The selection of electricity production modes and their economic
viability varies in accordance with demand and region

3. Fossil fuels
3
Fossil energy sources, including oil, coal and natural gas, are non-
renewable resources that formed when prehistoric plants and animals
died and were gradually buried by layers of rock. Over millions of years,
different types of fossil fuels formed -- depending on what combination
of organic matter was present, how long it was buried and what
temperature and pressure conditions existed as time passed.
Department of ECE -Sudar
4. Fossil fuels
We are using fossil fuels that were made more than
300 million years ago
Fossil fuels contain high percentages
of carbon and include coal, petroleum,
and natural gas.
They are not renewable; they can’t really be made

38. Problems of Power Dissipation
38
• Continuously increasing
performance demands
Increasing power dissipation of
technical devices
Today: power dissipation is a main
problem
High Power dissipation leads to:
High efforts for cooling
Increasing operational costs
Reduced reliability
Reduced time of operation
Higher weight (batteries)
Reduced mobility
Department of ECE -Sudar
39. Three factors that can reduce power dissipation are:
Voltage
Physical Capacitance
Switching Activity
Low Power Design Space
39Department of ECE -Sudar
44. Power Dissipation
Power dissipation is a measure of the rate at which energy is
dissipated, or lost, from an electrical system
When an electric current does work on a conductor, the internal
energy of that conductor increases, causing its temperature to
rise above the ambient temperature
This causes energy to dissipate away from the conductor into
the surroundings, through the process of heat transfer
The rate of this heat transfer (joules per second) is termed
'power dissipation' (in watts)
44Department of ECE -Sudar
45. Mechanisms of power dissipation
Mechanisms of power dissipation are usually divided into two
classes:
dynamic and
static power dissipation
Dynamic power dissipation occurs when the circuit is operational
Static power dissipation becomes an issue when the circuit is inactive
or in a power-down mode
45Department of ECE -Sudar
46. Dynamic Power Dissipation
Dynamic power dissipation can be further subdivided into three
mechanisms:
Switched
Short-circuit
Glitch power dissipation
This depends upon the activity, timing, output capacitance, and
supply voltage of the circuit
46Department of ECE -Sudar
47. Switched power dissipation
Repeated charging and discharging of the output
capacitance
Necessary to transmit information in CMOS circuits
47Department of ECE -Sudar
48. Short circuit Power Dissipation
Short circuit current occurs during signal transitions when both
the NMOS and PMOS are ON and there is a direct path
between Vdd and GND- crowbar current
Accounts for more than 20% of total power dissipation
As clock frequency increases- transitions increase consequently
short circuit power dissipation increases
48Department of ECE -Sudar
49. Glitch Power Dissipation
Glitches are temporary changes in the value of the output –
unnecessary transitions
They are caused due to the skew in the input signals to a gate
Glitch power dissipation accounts for 15% – 20 % of the
global power
49Department of ECE -Sudar
50. Static Power Dissipation
Power dissipation -device is in standby mode
As technology scales this becomes significant- Leakage power
dissipation
Reverse biased p-n junction
Sub threshold leakage
Channel punch through

51. Effects of Power Dissipation
Power dissipation affects:
Performance
Reliability
Packaging
Cost
Portability
51Department of ECE -Sudar
52. Miniaturization
Miniaturization is the trend to manufacture smaller mechanical,
optical and electronic products and devices
Advantages:
- Lower material costs
- Higher production output
- Potentially faster operation
Disadvantages:
- Increased complexity in circuit design (may lead to poorer
performance)
- Increased engineering/R&D costs
- Not serviceable after manufacture

Stop searching for the signal
Do not follow the method of full charge and
discharge
Avoid putting your mobile phone in vibrating
function
