Smart grids empower consumers to take charge of their energy systems and conserve resources by optimizing usage and effectively integrating renewable sources like solar PV. Furthermore, these grids improve system resilience and reliability by minimizing outages while responding quickly when outages do arise.

High-tech sensors monitor power flows and equipment performance in real time to quickly identify problems, signalling appliances and electric vehicle chargers to pause consumption during periods of peak demand, redirect power usage to reduce wasteful spending, or use battery storage systems as cost saving measures.

Real-time data

Smart grids use real-time data to detect potential issues and address them autonomously, leading to more efficient operation and lower costs. Real-time information also ensures quick response during power outages or natural disasters by monitoring voltage, current, load capacity and other sensors installed within their systems.

Smart grid systems rely on communication networks to transmit data between sensors and automated devices, as well as to transfer it through various protocols and technologies. These communication networks may be wired or wireless and employ various protocols and technologies that allow data transference between them. Communication networks play a crucial role in Smart grid operation by providing seamless transmission of information among sensors and automated devices.

Smart grids are also integral parts of energy transition as they facilitate integration of renewable energies like solar and wind power into the electricity supply grid, improving energy efficiency while simultaneously decreasing costs while improving sustainability and reliability. Their integration helps reduce fossil fuel usage as they also provide needed storage capacity to balance intermittent renewable sources like wind.

Real-time communication

Real-time communication is one of the key components that enable smart grids to function successfully, helping monitor, automate and optimize power systems to ensure greater energy efficiency and sustainability. This feature is particularly vital when dealing with renewable energies like wind or solar that cannot be programmed but require more reliable grid systems to control their output.

Sensors strategically distributed throughout the network monitor power flows and equipment performance, enabling operators to use software systems for analysis and address any potential problems immediately. This also facilitates more effective consumer participation in demand management and load shedding programs.

These systems also facilitate effective interaction with dynamic energy markets, enabling generators to sell their electricity at the right price and consumers to select optimal times for usage. This ensures a more reliable overall power supply by avoiding costly accidents and improving resilience within the grid. In addition, integrating renewable resources such as pumped-storage hydro power becomes more achievable through such systems.

Autonomous optimisation

Due to increased penetration of renewable energy sources, distributed storage devices, electric vehicles and building automation, the electricity system has become more complex. Advanced grid configurations that incorporate such elements present new communications, control and coordination challenges.

Autonomous optimisation offers a solution. ARKOS, an intelligent software platform, is capable of finding and implementing improvements that automatically increase performance without human involvement. ARKOS understands how multiple dimensions interact, providing holistic system excellence rather than individual improvements.

At our current project with a Norwegian power utility, we’re helping them make it easier to predict demand and engage distributed energy resources like rooftop solar and electric vehicles – creating a virtuous loop that keeps customers comfortable while saving them money and helping the environment simultaneously.

Self-healing

Imagine an electrical grid with the capacity to detect and repair faults within milliseconds, quickly restoring service quickly to customers affected by something as minor as a tree falling onto powerlines or something more serious like human error or even hacker attacks. Such self-healing capabilities could significantly decrease outages.

Researchers from Sandia National Laboratories and New Mexico State University are making this dream a reality through the collaborative research project CINELDI. Their team has developed methods that automate locating short circuit (symmetrical or unsymmetrical) faults in distribution networks more easily.

They can reroute electrical pathways around damaged areas and isolate it to one or two microgrids to minimize outages’ duration and impact. They strive towards this end using sensors, software algorithms, and automated switches which work like GPS for electrical systems.

While these capabilities may seem futuristic, they’re already in use today in limited ways. Grid-Edge DERMS platforms can monitor real-time and historical load forecasting tools; provide utility operators with device control for running demand flexibility programs like demand response or managed charging; as well as conservation tactics that reduce energy spending during peak usage times.
