Load control by IOT based efficient hybrid solar thermoelectric generation system by water cooling mechanism
Project Area of Specialization Electrical/Electronic EngineeringProject SummaryAs per energy demand is increasing day by day Thermoelectric devices are a great option to increase efficiency of renewable energy systems like solar, wind, thermal, hydro etc. With The help amazing properties of thermoelectric devices we can increase the efficiency of our renewable system like solar by 3.6% to 4.1% respectively with the help of decreasing temperature of solar panel and by adding generator source with the solar system will lead to increase its efficiency this can be possible by the effect of thermoelectric cell which are named as seebeck effect. with the help of seebeck effect of thermoelectric devices we can induce voltage by creating temperature differnce across the hot and cold side of thermoelectric cells. greater the temperature difference greater the induced voltage.however the overall efficiency of solar panel will rise because at high temperature the efficiency of solar panel decrease so when temperature of solar panel will be decrease it will lead increase the efficiency of solar system. we also connect some devices like MPPT controller and DC to DC Converter. These devices will filter the output power and boost up the output of overall hybrid solar thermoelectric system to maximum . The efficiency of solar pannel is increased upto 28% from 18% by water floating, CSP on thermoelectric cells and MPPT technique. in this study this maximum output power of hybrid solar Thermoelectric generation system will use for home automation this home automation is done by using nodemcu and Android app is developed to control the different types of electric loads of a home. To this complete automation setup the nodemcu controller is also used this controller will control the load with respect to the virtual command from the Android app to turn ON and turn OFF the electric load of different kind The Thyristors and relays are also used for this complete setup of automated home and this over hybrid solar thermoelectric generation system and IOT based Home Automation conclude that it is a best and efficient system to operate the electrical DC loads of a home with maximum output of electrical power.
Project Objectives- Determining a proficient MPPT algorithm for applications, to extract optimal power from the solar-panel.
- thermoelectric pannel are used in parallel with PV pannel in order to maximize the efficiency
- To offer a high-speed monitoring and low power fluctuation algorithm with optimized MPPT under changing environmental conditions.
- Control the home appliances through the smart IOT based application
- IOT based smart application will be developed which can be used for home automation
The first method that will be mainly implemented for extracting the maximum power from the pv pannel is perterb and observe. this method will be applicable on the solar pannel and yields the MPP ponit of the voltage,current curve.
Now the second method that will be applicable on the thermoelectric pannel is Concenterated Solar Power (CSP). in this method the hot side of thermoelectric cells are exposed to sunlight and this sunlight is focused on the cells by using convex lens, while the cold side of cells are floated on water in order to create big temperature difference between the hot and cold side of thermoelectric cells. greater the temperature difference greater the output power from the thermoelectric pannel.
the third and final method for controlling and managing the load is IOT based home automation .in this method, the load connetced with PV and thermoelectric pannel are turned on and off by using the android app which are interacted with wifi.
Benefits of the ProjectThe solar plays an important role in this era in which fossil fuels are depleting on its peak. The renewable source (solar) will be used and efficiency of solar will be increased in this project. The generation of solar will be used for home appliances and for making the home smart the IOT based smart application will be developed for home automation. Scope for the home automation systems involves making homes even smarter. Homes can be interfaced with sensors and provide automated toggling of devices based on conditions.
All group members will work together on the off grid hybrid solar thermoelectric generation system for home automation; this project stays within the necessary scope of the course. The most time spent on the project will take place during the design and testing portion, where the structure and actuation come together, and necessary changes will be made in order to achieve what is desired.

- Simulation and hardware of this project will be provided with report of this project
- Detail of deliverable:
- Affordable and Clean Energy
- We have used an affordable and clean energy in our project for power generation. Solar energy is the energy that can be easily affordable as it is directly coming from the sun. It is eco-friendly and clean.Solar energy does not emit toxic substances or contaminants into the air, which can be very damaging to the environment and to human beings. Toxic substances can acidify land and water ecosystems, and corrode buildings.
- Decent Work and Economic Growth
-
Over the past 25 years the number of workers living in extreme poverty has declined dramatically, despite the long-lasting impact of the economic crisis of 2008/2009. In developing countries, the middle class now makes up more than 34 percent of total employment – a number that has almost tripled between 1991 and 2015.
However, as the global economy continues to recover we are seeing slower growth, widening inequalities and employment that is not expanding fast enough to keep up with the growing labour force. According to the International Labour Organization, more than 204 million people are unemployed in 2015.
- Industry Innovation and Infrastructure
-
Investment in infrastructure and innovation are crucial drivers of economic growth and development. With over half the world population now living in cities, mass transport and renewable energy are becoming ever more important, as are the growth of new industries and information and communication technologies.
Technological progress is also key to finding lasting solutions to both economic and environmental challenges, such as providing new jobs and promoting energy efficiency. Promoting sustainable industries, and investing in scientific research and innovation, are all important ways to facilitate sustainable development.
