Energy management system for smart home

Smart Home Energy Management system (SHEMS) monitors and controls the loads existing in a residential home and manages the available energy effectively. It plays a significant role in smart grid environment and helps in regulating the wastage of energy at residential homes. It provides a homeowner the ability to automatically perform smart load switching based on generation power and home owner preference and load priorities. In the thesis, energy consumption and energy management problems have been studied and new approaches have been proposed. In order to achieve the objectives of the thesis, the embedded system consisting of microcontroller, sensors, actuators, internet hardware and display device has been designed and realized. In addition to embedded hardware design, embedded software and webserver for remote access and control are designed and implemented. Our energy management system for smart house proposed for energy saving has 3 different modes for load management. These are economic, auto, and manual modes. The system allows remote control of power tools using the Internet protocol via the Web server according to the set power. Thus, it provides energy savings and decreases the electricity bill. In order to solve the second problem discussed in the thesis, the required electrical appliances are powered up with control algorithm in the proposed system at the time when the electrical network is not over loaded. The performance and effectiveness of the proposed system according to different load and scenarios have been evaluated. As evaluation criteria's; availability to monitor home appliance status, energy management and ease of use of household appliances by the user, manageability by the control center, support of multi-power sources and communication technologies have been used. Test results showed that the system was designed and implemented successfully.
