S. Sonavane PG Student Guide & Director Department of Electronics & Telecommunication Engineering Dr. D. Y. Patil, School of Engineering, SPPU, Dr. D. Y. Patil, School of Engineering, SPPU, Pune, India Pune, India Abstract Electricity is one of the key factors in human life to survive on the earth. Most of our work requires electricity so it’s important to save electricity. Without electricity life will be like heart without heartbeats. Most of the electricity is generated from non- renewable sources like coal and fossil fuel which causes the pollution and affect the human life and day by day it is depleting so the cost of electricity is increasing .Smart grid is the electrical grid that is the collection of networks that supplies electricity to consumer and also monitor and analyzes the power consumption .Web of thing (WOT) are those thing which integrate the everyday object with web. This paper describes how to save electricity by using renewable sources and monitoring the resources and also controlling the resources by using WOT .By using raspberry pi controller along with sensors to control the devices which will set threshold value if it goes beyond the threshold value the appliance will turn on and web page will be created which will show how much power is consume by the appliances. By SMS alert the appliances can be turn off that will be sent to the authentic agent via GSM module. Keywords: Smart grid, Internet of things, renewable energy source, smart power grid, GSM, GPRS ________________________________________________________________________________________________________ I. INTRODUCTION Demand and supply of the electricity plays an important role. Earlier many things used to work without electricity i.e. very few things where automatic. But now we live in SMART world as the name suggest self-monitoring analyzing reporting technique in this the device itself monitors to him and if any problem arrive it reports to the system. Grid is the collection of the electrical network .Smart grid which supplies the power to the consumer and monitors the load power consumption and analyzes how much power is being used by the consumer. .Demand and supply ratio must be kept equal but now a days it is opposite supply we get is limited but demand is very high which cannot be fulfilled due to the depletion of the fossil fuel. It leaves behind carbon footprint which affects the living things. So to reduce the pollution Smart Grid as introduced which reduces pollution and also improves the efficiency of electricity. The main aim is to save electricity which uses fossil fuel and reduce the pollution. In the system solar panel is used as a renewable source the energy of this panel will be utilized by the devices. Web of things which will monitor and controlled the on off of the devices through web. Web page is created which will give the amount of power required in one day i.e. power consumption of the devices and if the devices are on with the help of the smart phone the devices can be made turn off if it is on so as to save electricity and energy. Load how much power it is consuming can be monitored and controlled with the help of the web page. Web page will have its own IP address to access once it is open we can monitored the device but to control the on off the password will be created for security purpose so that except that owner no one will controlled the device. This system is very advantageous like it automatically configure itself; it will act as a data logger to keep the track of the load power consumption saves electricity and does not pollute the environment. The system is eco- friendly. II. LITERATURE SURVEY Non-renewable resources have been the most exploited natural system, since man strode the earth. As a result of increasing population the use of electricity has been increased and other developmental activities, our system is being polluted by different origins. The use of the fossil fuel it pollutes the environment so by the use of the renewable resources ie sun we can save the non- renewable sources as well as reduce the pollution. C.Tsirmpas et .al proposed a new method for profile generation in an IOT environment: An application in ambient assisted living. The current paper serves well in providing a great deal of detail about how components of the IoT might collect data to be processed into contextual information by implementing the proposed methodology of profile generation [1]. Gomes, T proposed an FPGA-based edge device for the Internet of Things. The system proposed an FPGA-based edge device for IoT which uses System-on-Chip (SOC) FPGA technology to offload important features of the communication stack to dedicated hardware, aiming to increase system performance [2].
