The increased use of nonlinear loads in distribution system leads to distortion in voltage & current waveforms and injecting harmonics and thus the system inherently gets unbalanced. Harmonics generation becomes a grave concern in distribution system. Besides this, the voltage sag-swells and power factor also create the power quality problem at the utility side. Hence, reduction of these power quality issues in the system is important. There are other issues during installation of distributed generation, which must be evaluated and mitigated for the better performance of the system. The usage of power enhancement device such as unified power quality conditioner (UPQC) can simultaneously fulfil different objectives, such as maintaining a sinusoidal voltage at the point of Installation. The UPQC which has two filters (series and shunt active power filters) are to be placed in a distorted distribution line to provide the system sinusoidal current. This project proposes the placement of Unified Power Quality Conditioner (UPQC) for the power quality improvement and is to be tested in 33 bus radial distributed system.

Keywords : Distributed System, Filters, Harmonics, and Power quality improvement, THD, UPQC and Voltage Harmonics.

SWARM robotics or multi robot systems is a novel approach to the coordination of large numbers of relatively simple robots which takes its inspiration from social insects ants, termites, wasps and bees etc. Local communication can be achieved by different types of wireless transmission systems. Different types of sensing system, Communication system and design approaches are used in SWARM robotics. This paper presents a controller design and hardware specifications of robot for SWARM application using Arduino MEGA-2560 which is having Atmel’s ATmega2560 microcontroller. Implementation details are explained, and application of the multi-agent system is verified through algorithms. Multi Robot Communication is implemented to achieve Leader-Follower approach of SWARM navigation where leader robot guides the slave robots. Target Tracking or Move to Goal algorithm is implemented on robot which allows one robot to reach target directed by other robot. Communication between robots is achieved using low costCC2500 wireless transceiver module which is designed for very low-power wireless applications. The robot capability model and the task capability model are established, based on the distance between the robot and the target task and the matching degree between the robot capability and the task, a task allocation problem model is established to solve the problem of heterogeneous multi-robot collaborative task allocation.

Keywords : multi-robot system, heterogeneous robots, SWARM Robotics, Multi Robot Communication, Target Tracking, Arduino.

This paper presents an Arduino board which gives minimum power consumption at a reasonable cost. The security of this technique will be handled by a secure element. By using general purpose unit (GPU) the maximum internet of things (IoT) devices will be developed. The GPU is associated to a radio System on Chip (SoC). In this paper advanced four quarter security architecture will be developed for IoT design. A secure element will be functioned as identity module that executes transport layer security (TLS) packets, and sensor/actuator devices. The TLS secure element worked as an applicative firewall. The Aurdino based microcontroller is used to get low power consumption with low cost. This paper performs experimental platform, realizing a connected thermometer object, built around an Arduino microcontroller, cheap Wi-Fi SoC, commercial java card and temperature sensor.
