The reliability, efficiency, and controllability of Photo Voltaic power systems can be increased by embedding the components of a Boost Converter. Currently, the converter technology overcomes the main problems of manufacturing cost, efficiency and mass production. Issue to limit the life span of a Photo Voltaic inverter is the huge electrolytic capacitor across the Direct Current bus for energy decoupling. This paper presents a two-phase interleaved boost converter which ensures 180 angle phase shift between the two interleaved converters. The Proportional Integral controller is used to reshape that the controller attempts to minimize the error by adjusting the control inputs and also real coded genetic algorithm is proposed for tuning of controlling parameters of Proportional Integral controller. The real coded genetic algorithm is applied in the Interleaved Boost Converter with Advanced Pulse Width Modulation Techniques for improving the results of efficiency and reduction of ripple current. Simulation results illustrate the improvement of efficiency and the diminution of ripple current.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

3. INTRODUCTION
• Global warming is a major challenge to the world today and most power generating plants use fossil
fuels which is a major contributor to greenhouse gases.
• The constant emission of greenhouse gases into the atmosphere has caused deflection in the ozone layer.
• Wind energy is a great resource of renewable energy which is the alternative source of fuel to
hydrocarbon and shows great signs for reducing adverse environmental effects.
• There are several types of generators that be coupled to wind turbines to convert the kinetic energy of
wind into electrical energy. They are a doubly-fed induction generator, permanent magnet synchronous
generator, and Switched Reluctance Generator.
• Switched Reluctance Generator in comparison with other existing generators used for wind power
generation and the hybrid electric vehicle shows most favorable potentials such as low production cost,
good fault-tolerant, ruggedness, high starting torque, wide operation speed capability, and high torque-
inertia ratio . It has the problem of torque ripple, acoustic noise and vibration.
4. INTRODUCTION
• The Switched Reluctance Generator is simple in structure. It has both Rotor and Stator parts which are
both made of laminated iron.
• The Rotor is brushless and has no winding of any kind. The Stator has a winding which is concentric
coils wound in series on diagonally opposite stator poles. The different phase windings on the stator are
separately excited.
Due to the absence of windings on its Rotor, it experiences less loss and less heat is generated when
compared to other generators used for wind power generation.
It is finds relevance in wind power generation, aircraft starters and generators, hybrid electric vehicle
and industrial automation

5. STATEMENT OF PROBLEM
There is a large emission of carbon into the atmosphere and this has caused an
imbalance in our ecosystem. Most sources of energy involve the burning of fuel which
releases carbon gas into the atmosphere. Wind energy is environmentally friendly. All
generators used in wind farms have limitations.
Double-fed induction generator has the problem of rotor losses, brush maintenance,
and grid support
A permanent magnet synchronous generator has the problem cost due to the high cost
of a rare-earth permanent magnet.
Switched Reluctance Generator has the potential to perform better than other types of
existing Wind energy generators. But has the problem of control for a stable operation
due to its nonlinear nature of flux distribution. And this causes high torque ripple,
acoustic noise and makes its control very difficult.
Due to the nonlinear distribution of flux, Switched Reluctance Generator has a problem
of acoustic noise, torque ripple and difficulty in control

• MATLAB design and simulation of Switched Reluctance Machine operating its
generating mode
• Mitigation of acoustic noise and torque ripple using intelligent controllers such as
sliding mode or fuzzy logic controllers
• Optimization of the firing angle of the Switched Reluctance Generator using Firefly
optimization algorithm for optimal performance
• Verification of simulated result through practical laboratory design and
experimentation of the switched reluctance generator coupled to a wind turbine
AIMS AND OBJECTIVES OF THE RESEARCH
7. There are lots of reviews on the performance analysis of a Switched Reluctance Motor but little has been
done on the control of a Switched Reluctance Generator. Below are some of the notable contributions to
the development of the Switched Reluctance Generator.
Zeki and Ceren [2] in their study on the control of switched reluctance generator in power system
application for variable speed, simulating the output voltage control of a switched reluctance generator
using a PI voltage controller on a MATLAB/SIMULINK software. The obtained simulated result was
compared to the experimental result and it was observed to be similar. It is also proven from their work
that changes in phase current are affected I the choice of turn-on and turn-off angle.
Kim and Ha [3] in their work on the speed controller of an SRM, were able to significantly reduce the
problem torque ripple and enhance high control performance by optimizing a PID controller with the
help of a Genetic optimization algorithm
Pillay et.al [4] proposed a new method of minimizing the problem of torque ripple of an SRM which is
based on the control of the sum of the square of the phase currents. The method makes use of two
current sensors and analog multipliers. A sliding mode controller was used to control the speed.
