Smart homes have the potential to increase energy efficiency, reduce energy costs and reduce the carbon footprint by including renewable energy sources in the energy mix and transforming the role of consumers. The Key to smart homes is power management systems. They are based on innovative technologies in the field of power grids and consumer electronics.
The modern home is a well-designed center for energy transmission between the electricity grid and a different combination of appliances and systems. In the case of intelligent residential prefabricated buildings, there is two-way communication. It is performed from and to the utility network, which is carried out by means of smart meters. They interact dynamically with the network system, receive signals from the service provider and respond with consumption and diagnostic information. This two-way exchange of information is made possible by Advanced Metering Infrastructure (AMI). It has intelligent functions for tracking energy consumption. Combined with the appropriate communication tools for reliable data exchange with other stakeholders in the network.
Automated Home Energy Management (AHEM) networks independently manage end-user systems based on information from occupants and smart meters. The advantages of using such a network are indisputable. It aligns the energy consumption of the connected systems in the home with the consumer's comfort and price goals, as well as with the information received from the service provider. Sensors and controls in such a solution work together in a wireless home network (HAN). They collect relevant data, process the information through the necessary algorithms, and implement management strategies. They aim at improved comfort at minimal cost to residents, efficient consumption, and timely response to service provider requirements.
More and more utility providers are providing near real-time energy consumption data to homeowners. Along with the different types of pricing schemes and recommendations for reducing the consumption of electrical loads. Many companies have also introduced web-based or mobile-based user interfaces. Through them, owners of smart passive homes can adjust the parameters of their room thermostats or control their lighting remotely using a smartphone or browser. Advanced metering of network parameters using the appropriate AMI infrastructure is also being offered by more and more energy providers.
