From HoD’s Desk
Greetings!
Wishing
you and your loved ones a very happy new year!!
As
we step into a new year, we wish and pray that we find an end to the
challenges of Covid-19 and find a return in normalcy in our teaching-learning
and academic activities in the coming year. As we sit and reflect on the
past year, it seems 2021 has been a year of two halves. If the
first half was about online teaching, the second half was about offline
teaching. However, all the examinations were conducted in an online mode. 2021
has been a year of perseverance and patience, and none other than the
students of K. K. Wagh have demonstrated it so well.
Despite
the challenges in the past year, we have been successful in continuing our
journey in imparting quality technical education and making students ready for
the industry. Each class and division of our department has worked towards its
goal of achieving academic excellence. We look forward to working hard at all
fronts for the overall development of the students and Department to take our
institutes to higher heights. Let us connect, engage and collaborate towards
our common goal of developing our institute and ecosystem.
Once again have a safe, healthy, and prosperous New Year!

Solid-State Battery
Pranjal Jain, TE (Electrical) Div. B (pranjaljain.1112.rj@gmail.com)
Solid-state batteries are low-cost batteries totally based on solid electrolytes that are inflammable and have a long cycle life with a high volumetric energy density and speedy rates of charge and discharge. Solid-state batteries use glass, ceramic and other solid materials as an electrolyte.
Market research companies expect that Electric Vehicles (EVs) will replace internal combustion engine vehicles (ICEVs), become the mainstream in the auto industry and have the potential to become the leader in the market. EV should have a similar level of mileage as the current ICEV and for that increment in the battery capacity is vital. Well, there are two ways to enhance capacity. The first is by increasing the number of batteries. However, batteries will take a lot of space in the vehicle and also it will directly affect the prices of EVs. A solid-state battery has a higher energy density than a Li-ion battery that uses liquid electrolyte solution. It does not have a risk of explosion, so there is no need to have components for safety. We have more space to put more active materials, which increases battery capacity in the battery. A solid-state battery can increase energy density per unit area since less number of batteries are needed. For that reason, a solid-state battery is perfect to procure an EV battery system of modules and pack, which needs high capacity. The solid-state battery can provide three times the energy density and hence the idea of using an alkali metal anode (Lithium, Sodium, or Potassium) came as a blessing. It enhances the energy density of the cathode and delivers a long life cycle.

What users are most worried about the lithium-ion
battery is its safety. As lithium-ion battery uses liquid electrolyte in which
the main ingredient is ethylene carbonate which is flammable. It has a risk of
battery damage such as swelling caused by temperature change or leakage caused
by an external force. To prevent this we need devices or components that can
improve safety. However, a solid-state battery with solid electrolyte improved
stability with a solid structure and increased safety since it maintains the
form even if the electrolyte is damaged. A solid-state electrolyte is
non-combustible or at least resistant to self-ignition which reduces the risk
of thermal runaway, allowing for a tighter packaging of the cells and
consequently improving the design flexibility and volumetric density.
The challenges in improvement are converting the
insertion or deposition of the solid electrolytes to a method that is well
suited with the latest manufacturing practices, all without affecting the
durability or cost of the final product even as including benefits such as
better energy and power density, increased safety and higher throughput.
Current technology would not be able to make the development required for the less
expensive electric vehicle. They may be attractive but far more costly because
of the rate of the battery, as the battery is the bulk of the vehicle cost.
Toyota appears to be preparing to scale up to mass production relatively soon.
Samsung SDI is currently working on developing the solid-state battery with
Samsung Advanced Institute of Technology, Samsung R&D Institute Japan and
others. The study of the technology that increases life cycle and safety and
reduces the size of a solid-state battery is necessary for their curriculum.
Quantumscape (QS) is a solid-state battery manufacturer which was founded in
2010 to develop scalable, effective solid-state batteries. Quantumscape has
established itself as one of the global leaders in solid-state battery
development. In December 2020, the battery developer used ceramic as a
separator and announced a major breakthrough in its technology. Quantumscape
has new information showcasing a further development of its solid-state
batteries, whose cells have completed 400 consecutive 15-minute fast-charge
cycles, replenishing from 10% to 80% capacity at the same time and still
maintaining over 80% of the initial strength. As a pioneer of this type of
battery technology, Quantumscape ensures that it can revolutionize the charging
time of EVs with a much more low level at station fill-ups and ultimately
promote the EV technology. Along with these, Contemporary Amperex Technology Co.
Ltd., Automotive Cells Co with Total Energies, Ford Motor Co (F.N), and BMW AG
(BMWG.DE) working on solid-state batteries.

Artificial Intelligence in Power Systems
Vedika Dharaskar, BE (Electrical), Div. A (vedika.dharaskar@gmail.com)
Introduction:
Artificial
Intelligence is one of the latest technology, having the abilities like
decision making, solving problems by reasoning, heuristics, and judgment,
rectifying mistakes. This term was coined by McCarthy in 1956. Artificial
intelligence is known to be the intelligence exhibited by machines and
software. AI can be used, when the problems are difficult or cannot be solved
by human intellect. The use of artificial intelligence technology can
significantly improve the efficiency of electrical automation control, and
further, expand the scope of electrical automation control applications.
AI
Techniques: The two main
techniques are Fuzzy Logic and Artificial neural network. The term fuzzy refers
to things that are not clear or are vague. It helps to represent the state with
a degree. The membership function helps determine the degree of the state. The
value of the membership function is between 0 to 1. Fuzzy systems are similar
to human decision making they have the ability to produce exact and accurate
solutions from certain or even approximate information and data.
|
Input Layer: The main
function of input layer is to transmit the signal to other units without
any modification in data and information. Hidden Layers: The
hidden layer is not directly visible. They provide the ability to map or
classify the problems. Output Layer: They encode the possible values to allocate the case under consideration. |
AI
in Power system: Let
us consider a transmission line, if there is any fault it is detected by the
fault detector and transmitted to the fuzzy system. The input to the fuzzy
system is the angular difference between fault and pre-fault current phasors.
Fuzzy systems help to obtain the crisp output and fault type.
ANN is used
to sense environmental conditions, which is an input to Expert systems. The
computer programs help to determine the line parameters. The ANNs change the
value of line parameters in the given range based on environmental conditions.
They are trained with algorithms. The neural networks are further tested and
performance is evaluated. If the evaluated performance is not according to the
required standard, the numbers of neurons are varied in each layer. Hence,
fuzzy systems can be used for fault diagnosis and ANNs can be used to improve
the performance of the line.
AI is also
used in the planning of power system generation, power system reliability,
transmission expansion planning, reactive power planning. They can also be
implemented for control in the power system that is voltage control, stability
control, power flow control, load frequency control.
