Smart grids use sophisticated monitoring and control systems to optimize their electricity network and achieve greater efficiencies and reduced energy waste while simultaneously supporting renewable integration.
Multiple technologies are implemented, such as PMUs that take 30-60 measurements every second, relays that detect and recover from faults automatically, and automated feeder switches which reroute power around issues.
Reliability
Utilizing smart technology, utilities can predict and smooth out energy production, taking peak and trough patterns into account. This enables utilities to more efficiently utilize resources while decreasing consumption and waste – saving both the environment and consumers money in the process.
Smart grids allow users to monitor power usage and quickly react to high energy usage levels, thus lowering the risk of power blackouts and saving man hours, travel costs and energy expenditure.
Smart grid reliability depends on several factors, including resiliency, software component, and standards. This study uses multiple-criteria decision making (MCDM) to assess these aspects; specifically three main criteria and fifteen supporting sub-criteria were examined using Fuzzy Analytic Hierarchy Approach (FAHP). Furthermore, twenty experts were interviewed in order to gather additional data.
Efficiency
Smart grids are energy systems designed to monitor parts of the power system at higher resolution in time and space, enabling energy providers to more effectively balance supply and demand. This enables energy providers to decrease outages due to equipment failure or severe weather events and limit their impact on human life and critical infrastructure.
Smart meters help increase efficiency by connecting consumers directly with suppliers, relieving peak usage times. Homeowners can use them to monitor real-time pricing information and schedule low priority devices like water heaters so that they run off cheaper electricity during off-peak periods; electric car (EV) owners can even use smart meters to ensure they charge their car at times when electricity prices are at their lowest point.
Smart grids enable consumer-driven energy solutions such as microgeneration. Residential PV solar systems may feed excess power back into the grid if they produce more than they require, thus relieving demand on larger central power plants.
Integration of renewable energy
As renewable energy becomes more widely adopted, Smart grids have evolved to incorporate multiple sources of power into their operations – enabling consumers to take advantage of solar panels and other localized sources that produce energy, thereby helping reduce electricity bills.
Smart grids differ from their traditional counterparts by providing two-way communication among sensors and control devices. Sensors collect information on the status of power networks, transmit it to computation devices that make adjustments and communicate those changes to control systems for implementation.
Real-time power flow monitoring provides greater efficiency and reliability for power systems, enabling them to adjust energy distribution based on demand and weather conditions, or implement demand response programs to encourage consumers to shift consumption during peak usage periods to help ease strain on power networks.
Sustainability
Smart Grids use advanced technologies for communication, simulation, and sensing in order to provide easier access to electricity. Prosumers – consumers who produce and consume electricity simultaneously – are able to safely connect using control systems, net metering tariffs, or time of use tariffs.
Also, they improve the utilisation efficiency of power systems by lowering energy consumption and carbon emissions, and supporting electric vehicles (EVs) and decentralized energy generation to further decrease our dependence on nonrenewable sources of energy.
These systems also make it easier to combat disasters that affect centralized power plants by providing alternative sources of energy that can fill in when necessary, giving an unprecedented level of redundancy that would otherwise cause blackouts across an entire city. This factor plays an essential role in energy sustainability.
