This document discusses the design and implementation of a grid-tied inverter (GTI) system. A GTI converts DC power from renewable energy sources like solar panels into AC power that can be fed into the electric grid. The system uses a full-bridge inverter with IGBT switches to convert the DC voltage into an AC voltage. A microcontroller is used to generate pulse width modulation signals to control the switches and synchronize the output with the grid voltage. Experimental results showed that the GTI output a sinusoidal waveform that matched the frequency, amplitude, and phase of the grid voltage. The GTI allows renewable energy to be integrated with the electric grid in a synchronized manner.
Photovoltaic Management System in Residential Areas Using Power Line Communic...IJTET Journal
Abstract— Energy consumption in residential areas is rising; residential areas have deployed a photovoltaic (PV) system to save
energy cost and provide continuous power in the area. The PV system needs to be continuously monitored to maintain its performance.
In addition, it is desirable to monitor each PV module because one abnormal PV module affects the whole PV system. Here Power line
communication (PLCC) technology is used to monitor each PV module in order to check the performance of PV system. Power line
communication (PLCC) carries data on a conductor that is also used simultaneously for AC electric power transmission. The
parameters in PV module are monitored by PLC. The system architecture is composed of the following components: PLC modem,
CUK Converter, and inverter connected with AC load. The PLC modems are deployed on each PV module for continuous monitoring.
The CUK converter will provide constant voltage to the battery. The device retrieves the stored data in microcontroller unit and
informs users about the status of the photovoltaic module. The device retrieves the stored data from the converter to inform users of
the status of the PV system. Voltage, Current and Temperature are the parameters which are going to be noted in PV module. The
output of the inverter circuit is given to the AC load by using resistive load. Users can browse and figure out the PV system
performance in detail by using power line communication technology. The system is installed in the field.It is composed of sixteen PV
modules with 960V; since each PV module provides 60V and a 1kW inverter. This scheme will maintain the performance of a PV
system and can be used for industrial applications.

Intelligent Electric Power Management Using Zigbee with Advanced Metering Inf...Akbar Badusha
This project mainly focuses on reduction of power cut and power theft. The main reason for the power cut is shortage of power in the generation unit. We can rectify this problem through our project.
Whenever the generation falls behind a particular limit (it is set initially by EB) the power management system will automatically switched on. Power will be supplied to only the basic necessary equipment (as stated in the priority list) power to other load will be stopped so that huge amount of power can be saved without power cut.
In our project, this is achieved using NS2 software and using ZIGBEE. Whenever generation falls below the particular value, then the load will be automatically switched off based on priority. And it can also be done through an interrupt. Through ZIGBEE command the interrupt will be sent to microcontroller to cut the power to the particular load.
When microcontroller receiving the command, the relay will cut the power to the equipment. So the power will be saved.
In this project,the method to detect and to control the power theft is also stated. Other methods of power theft like damaging, by passing electrical power meter can also be detected and can be punished.
Man power can also be reduced. The power usage of the customer will be automatically updated in the EB station so there is no need of man power to take meter reading in the user side. After every two months the reading will be automatically resetted.

Automatic power factor_improvement_and_monitoring_by_using_plc[1]ferozpatowary
Power factor correction (PFC) is a process of negotiating the unwanted effects of electric loads that create a power factor less than one. Power factor correction may be applied either by an electrical power transmission utility to enhance the efficiency of transmission network. In this paper three transformers of different ratings have been used which acts as inductive load each of which produce different power factor variation. The power factor of the supply line is directly monitored by the Power Meter which is connected in parallel to the supply line. The value of the capacitance (capacitor bank) required for correcting the power factor variation due to each transformer and their combination is found out separately. Capacitor bank for the respective load is triggered by using PLC.

Design and Construction of Automatic Three Phase Power System Selectoriosrjce
The automatic three phase power system selector was designed and constructed. The device
automatically switches over to the alternative phase that has current when there is power outage or extremely
low current in the phase which the load is connected without the power being off. The selector links the load and
the other phases and relay switches allowing the usage of the remaining phases where there is outage on the
mains source without disturbing or interrupting the load. It maintains constant power supply to the load by
automatically activating the phases when the need arises. This safeguards the electronics system from being
damaged and burnout as a result of voltage instability, collapse, insistent outages which are paramount in
under developed and developing countries
This paper describe the design and
implementation of an “Automatic method of protecting

The aim of this paper is to provide an alternative, effective,
efficient and more reliable method of protecting fault from
power transformer which may arose as a result of overload,
high temperature or a high input voltage. Generally, fault may
occur in transformers due to the stated reasons. To safeguard
the damage of the transformer with the aid and help of
microcontroller we monitor and control the entire circuitry.
Thereafter regarding the monitoring and control, information
about the operation of the parameters would be transmitted to a
personal computer for general monitoring and control, which
avoid the need of the lines men who had to go to the transformer
to re-fix fuses. Lastly, a working system was demonstrated to
authenticate the design and possible improvements were also
presented.

AUTOMATIC VOLTAGE CONTROL OF TRANSFORMER USING MICROCONTROLLER AND SCADA
LABVIEW PROJECT FINAL YEAR EEE
ABSTRACT: A tap changer control operates to connect appropriate tap position of winding in power transformers to maintain correct voltage level in the power transmission and distribution system. Automatic tap changing can be implemented by using µC. This improved tap-changing decision and operational flexibility of this new technique make it attractive for deployment in practical power system network. This paper deals with the implementation of µC based tap changer control practically, using special purpose digital hardware as a built-in semiconductor chip or software simulation in conventional computers. Two strategies are suggested for its implementation as a software module in the paper. One is to integrate it with the supervisory system in a substation control room operating in a LAN environment. In this configuration, the parallel transformers can be controlled locally. The other is to integrate it into the SCADA (Supervisory Control and Data Acquisition) system, which allows the transformers to be monitored and controlled remotely over a wide area of power-network. The implementation of µC based tap changer control needs interfacing between the power system and the control circuitry. µC s may need to interact with people for the purpose of configuration, alarm reporting or everyday control.
A human-machine interface (HMI) is employed for this purpose. An HMI is usually linked to the SCADA system’s databases and software programs, to provide trending, diagnostic data, and management information such as scheduled maintenance procedures, logistic information, detailed schematics for a particular sensor or machine, and expert-system troubleshooting guides.
OBJECTIVES: The original system can afford the following features:
- Complete information about the plant (circuit breakers status, source of feeding, and level of the consumed power).
- Information about the operating values of the voltage, operating values of the transformers, operating values of the medium voltage, load feeders, operating values of the generators. These values will assist in getting any action to return the plant to its normal operation by minimum costs.
- Information about the quality of the system (harmonics, current, voltages, power factors, flickers, etc.). These values will be very essential in case of future correction.
- Recorded information such case voltage spikes, reducing the voltage on the medium or current interruption.
- implementation of µC based tap changer control practically, using special purpose digital hardware as a built-in semiconductor chip or software simulation in conventional computers.

HIGH EFFICIENT BRIDGELESS BOOST RECTIFIER FOR LOW VOLTAGE ENERGY HARVESTING A...IAEME Publication
A single phase ac-dc bridgeless boost rectifier for low voltage energy harvesting applications is proposed in this paper. The conventional bridge type boost converters for low voltage energy harvesting requires more components hence they suffer from high power loss and require more number of energy storage components like inductors and capacitors. Conventional converters can be modeled for boost operation or buck-boost operation alone. The proposed converter overcomes the above mentioned draw backs of conventional converter. Detailed analysis of proposed convertor is also presented under boost, buck-boost mode operations. The proposed converter operation is analyzed using MATLAB/SIMULINK environment both open loop and closed loop conditions.

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.
