Smart home energy management system
Project Area of Specialization Internet of ThingsProject SummaryThe main objective of this report is to present our idea of developing a Smart Home Energy Management System and why it is important and what’s the benefits of having a SHEMS installed.
As the era is changing, houses are also getting smarter. Homes are shifting from manual control system to a centralized control system. Users can control the home appliances with their mobile phones, or they can schedule the devices usage hours. By scheduling the hours of device usage, the devices will be turned on and off automatically according to the scheduled time.
The key challenge is to provide an automated home along with the minimum power usage. Providing the user comfort and reducing the power consumption at a time is not an easy task. It requires the use of algorithms to find the best power optimization techniques. It varies from user to user due to different usage patterns of appliances. Furthermore,algorithms use many parameters to find the best scheduling of devices usage. Parameters may include the user time of use, off peak hours and renewable energy (if available).We will develop a SHEMS which uses multiple power optimization techniques at a time to give the best outcomes. It involves the calculating of multiple algorithms outcomes and choosing the best one. Our system will provide one solution to many problems at the cheapest first cost. Getting all these services at a cheap installation cost will make it more feasible for real home use. We are expecting 10 – 30 % minimum power saving after installing SHEMS at homes. It may vary from person-to-person usage patterns and algorithm implemented.
Project ObjectivesIn this project we are proposing a SHEMS that can bring ordinary devices in
- We will ensure the comfort of user while optimizing the power usage.
- We will develop a system in which a user can interact with household appliances with intelligent inputs.
- We will identify the best procedure to find the optimization goals.
Electrical equipment in the home can be split into two groups based on the preferences of the user. The first group consists of non-shiftable vital loads such as televisions, computers, and microwaves. Non-critical loads, such as electric vehicles, washing machines, and dishwashers, fall into the second category. Deferrable and non-deferrable loads are the two categories of loads. Commercially available smart plugs are used to monitor and manage the appliances, and they interact with the central computer via the Raspberry Pi protocol. These plugs have the capacity to monitor appliance energy use and turn on/off their own outputs.
HEMC schedules the appliances for 24 hours, and each appliance is assigned to a specific time slot in the Scheduling Section. During the 24-hour intervals, each time slot is designated as one hour. For the whole day, there are a total of 24 time periods. These time slots are allocated according to the peak and off-peak pricing systems' established rates. If the schedule reveals peak hours, appliances are moved to off-peak times. Assume a two-hour time window is set for an appliance, but the user turns it off after one hour and ten minutes. The rest of that slot's time (fifty minutes) will be squandered. Rescheduling an appliance is
accomplished via coordination and GT rather than spending the remaining time. To achieve the best results, three GT variations (ZS, NE, and SV) are compared. When a user turns off an appliance before its operating period is over, RS receives an interrupt from AS and then executes appliance coordination. RS discovers the following information about appliances at first:
• Which appliance has reached the end of its service life?
• Can any of the appliances be rescheduled?
• What appliances are currently in use?
The main panel of smart HEMS may also receive real-time power consumption data from in-home appliances, including programmable and non-programmable equipment, to perform optimal demand dispatch.
Benefits of the Project1:The comfort of user while optimizing the power usage.
2:System in which a user can interact with household appliances with intelligent inputs.
3:The best procedure to find the optimization goals.
Technical Details of Final DeliverableWe will implementing a Smart Home energy management system using a Wi-Fi module. In this design, a Wi-Fi module is used for communication between input and output devices. By using a Wi-Fi module, we will try to reduce the complexity of circuit design. The basic goal of using Wi-Fi in SHEMS is to create low-bandwidth digital low-power communication systems.
Wi-Fi technology can enable SHEMS to collect energy data in real-time, allowing users to operate smart home devices more intelligently and efficiently.
The proposed Energy Management System is divided into two sections:
- hardware section that describes the physical devices that make up the system, and a
- software section that describes the various packet exchanges between devices as well as the protocol that is employed.
