As a core component of modern electricity metering and management, electronic (smart) energy meters are widely deployed across every stage of the power lifecycle-including generation, transmission, distribution, and consumption-and serve as a critical data foundation for the development of smart grids and smart cities.
Electronic multi-functional energy meters are extensively utilized in substations across various voltage levels within power systems, for electricity settlement in diverse power generation plants, and for the precise metering of electricity consumption by large-scale industrial enterprises.
Smart meters enable the accurate and real-time processing of billing and settlement information (billing and accounting). By establishing additional measurement nodes on the user side, these devices capture more precise data regarding load profiles and grid losses; this capability helps prevent power equipment overload and the deterioration of power quality, while also facilitating the estimation of unknown system states and the verification of measurement data accuracy (distribution network state estimation). The adoption of smart meters allows for the real-time monitoring of power quality and supply conditions, thereby enabling timely and accurate responses to customer complaints and the proactive implementation of measures to prevent power quality issues (power quality and supply reliability monitoring). Furthermore, smart meters facilitate the estimation and forecasting of aggregate energy consumption and peak demand (load analysis, modeling, and forecasting). Through smart meters, utilities can remotely connect or disconnect entire load groups-or exercise control over specific subsets of users-thereby coordinating with dispatch centers to execute power control strategies (remote load control). As a vital source of foundational data for the smart grid, smart meters-when integrated with big data analytics-enable the delivery of enhanced services to end-users.
Electronic energy meters play a pivotal role in energy (and energy conservation) management systems. Smart meters empower users by providing optimized strategies for electricity generation and consumption, thereby maximizing user benefits (energy efficiency monitoring and management). Leveraging the data provided by smart meters, users can establish personalized energy management systems designed to minimize energy consumption and achieve emission reduction targets (user energy management). By furnishing users with real-time energy consumption data, smart meters encourage the adjustment of usage habits and facilitate the prompt detection of consumption anomalies-such as those caused by equipment malfunctions-thereby promoting energy conservation (energy conservation).
In areas prone to high rates of electricity theft, smart meters enable the cross-verification of data between master meters and all downstream sub-meters, thereby facilitating the timely detection of potential instances of electricity theft (detection of unauthorized electricity usage).
Smart meters support mobile applications that allow users to conveniently access information-such as electricity tariffs, remaining credit balances, and total consumption-and to make one-click payments. By enabling remote, automated meter reading, smart meters have fundamentally transformed traditional operational workflows. IoT water meters can capture a household's water usage data and transmit it to a cloud-based database. Through algorithmic analysis, if it is detected that a solitary elderly resident suddenly exhibits an abnormally low level of water consumption, this serves as an indicator to determine whether the individual has encountered a sudden emergency and requires assistance.
