Energy crisis is the most important issue in today's world. Conventional energy resources are not only limited but also the prime culprit for environmental pollution. Renewable energy resources are getting priorities in the whole world to lessen the dependency on conventional resources. Solar energy is rapidly gaining the focus as an important means of expanding renewable energy uses. The designed tracker has precise control mechanism which will provide three ways of controlling system. A small prototype of solar tracking system is also constructed to implement the design methodology presented here.
Presented is a street lights control system based on AT89S52 as control core. This design can save a great amount of electricity compared to streetlamps that keep alight during nights. The design implements traffic flow magnitude statistics without adding any hardware, facilitating transportation condition information collecting. Furthermore, this system has auto-alarm function which will set off if any light is damaged and will show the serial number of the damaged light, thus it is easy to be found and repaired the damaged light.

DESIGN AND CONTROL OF MICRO GRID FED BY RENEWABLE ENERGY GENERATING SOURCES.
This paper presents a control of a micro grid at an isolated location fed from wind and solar based hybrid energy sources. The machine used for wind energy conversion is doubly fed induction generator (DFIG) and a battery bank is connected to a common dc bus of them. A solar photovoltaic (PV) array is used to convert solar power, which is evacuated at the common dc bus of DFIG using a dc–dc boost converter in a cost effective way. The voltage and frequency are controlled through an indirect vector control of the line side converter, which is incorporated with droop characteristics. It alters the frequency set point based on the energy level of the battery, which slows down over charging or discharging of the battery.
Power distribution system is a highly critical infrastructure for modern power grid. In recent years, with the large scale integration of intermittent renewable energy generation which causes instability in the power grid, the power quality problems in distribution system have earned widespread attention. Electric spring (ES), a new smart grid technology, has earlier been used for providing voltage and power stability in a weakly regulated/stand-alone renewable energy source powered grid. It has been proposed as a demand side management technique to provide voltage and power regulation.

Agriculture is humankind’s oldest and still its most important economic activity, providing the food, feed, fiber, and fuel necessary for our survival. With the global population expected to reach 9 billion by 2050, agricultural production must double if it is to meet the increasing demands for food and bio-energy. We have developed an automated water well/lift pump station powered by solar or wind. Our expertise is in providing custom automated agriculture water controls to increase crop and grass land and increase profitability for farmers and ranchers.
Our control systems include instruments such as solar powered wireless field sensors to turn irrigation pumps On/Off based on moisture content in the earth or when a tank or trough is full. We also can provide you with remote controls to control and monitor your system using wireless radio or cellular telemetry communications to a computer and smart phone.
The control and monitoring system presented is based on Supervisory Control and Data Acquisition concept. It provides GUI service for operators and data visualization capability to display data trends using an appropriate DBMS (database management system). The SCADA system also incorporates Alarm and PAS (public address system) for operational and functional safety. The remote control of the gates is carried out through PC based SCADA software from a centrally located control room. The SCADA system consists of a Master Terminal Unit (MTU) located in the control room, MicroLogix 1400 PLC-based Remote Terminal Units (RTUs) located in the control panels of dam gates, and ultrasonic sensors equipped with MODBUS/ RTU interface to measure upstream and downstream water levels.
SMART ROADS AND INTELLIGENT HIGHWAYS WITH WARNING MESSAGES AND DIVERTING ROUTES BASED ON CLIMATE CONDITIONS.
VOICE CONTROL HOME AUTOMATION
Traffic accidents have become an important problem for governments, researchers and vehicle manufacturers over the last few decades. However, accidents are unfortunate and frequently occur on the road and cause death, damage to infrastructure, and health injuries. Therefore, there is a need to develop a protocol to avoid or prevent traffic accidents at the extreme level in order to reduce human loss. The aim of this research is to develop a new protocol, named as the Traffic Accidents Reduction Strategy (TARS), for Vehicular Ad-hoc networks (VANETs) to minimize the number of road accidents, decrease the death rate caused by road accidents, and for the successful deployment of the Intelligent Transportation System (ITS).
A fully autonomous home is going to be the future. Everyone want that the complete control such as switching on/off the lights, fans, televisions and other appliances through one device. This paper presents a novel solution that makes this future a bit nearer. Voice controlled automation, as well as a universal remote control application on an Android platform, has been presented. The efficient utilization of various available apps on Google play store has been done. Using the Bluetooth module HC-05, Arduino Uno, and Android application, voice controlled automation, as well as the universal switch, has been realized.
