Utilities also benefit from a modernized grid, including improved security, reduced peak loads, increased integration of renewables, and lower operational costs. These advanced technologies include advanced sensors known as Phasor Measurement Units PMUs that allow operators to assess grid stability, advanced digital meters that give consumers better information and automatically report outages, relays that sense and recover from faults in the substation automatically, automated feeder switches that re-route power around problems, and batteries that store excess energy and make it available later to the grid to meet customer demand.
Over the years, OE has continued investing in the research, development, and demonstration of advanced technologies while also developing new modeling and analytics capabilities that can evolve as technology and policy needs mature.
OE leads national efforts to develop the next generation of technologies, tools, and techniques for the efficient, resilient, reliable, and affordable delivery of electricity in the U. More options.

The authors have compiled and integrated different aspects of applied systems optimization research to smart grids, and also describe some of its critical challenges and requirements. The promise of a smarter electricity grid could significantly change how consumers use and pay for their electrical power, and could fundamentally reshape the current Industry.
Gaining increasing interest and acceptance, Smart Grid technologies combine power generation and delivery systems with advanced communication systems to help save energy, reduce energy costs and improve reliability. Taken together, these technologies support new approaches for load balancing and power distribution, allowing optimal runtime power routing and cost management. Such unprecedented capabilities, however, also present a set of new problems and challenges at the technical and regulatory levels that must be addressed by Industry and the Research Community.
It is less emphasized in definitions offered by national and international instances working on smart grids whereby mainly the benefits are addressed some more challenges are mentioned at the bottom of this article. It introduces a two-way dialogue where electricity and information can be exchanged between a utility and its customers.
The EU defines a smart grid as follows: a smart grid is an electricity network that can cost-efficiently integrate the behavior and actions of all users connected to it — generators, consumers and those that do both — to ensure economically efficient, sustainable power system with low losses and high levels of quality and security of supply and safety. According to the EU a smart grid employs innovative products and services together with intelligent monitoring, control, communication, and self-healing technologies to:.

Similar smart grid definitions exist in other regions through the world where smart grid initiatives exist which is the case for most countries, obviously including the US. The U. It sums up some benefits associated with the Smart Grid again, the initiative, but you can expand it to smart grids overall :. Obviously, there are also challenges regarding the movement to a smart grid.

Additional ones include consumer concerns privacy and personal data protection and cybersecurity. A second challenge is certainly the overall cybersecurity aspect which is typical in all industrial environments where digitization and digital transformation are ongoing, data become key and IT and OT converge IT stands for information technology, OT for operational technology. Additional challenges in smart grids include regulatory changes, the complexity in integrating sources, systems and partnerships between various players in a deregulated market, the local situation whereby a selected number of large companies often still dominate and changing attitudes among prosumers.

The goal of this article was to introduce smart grids and explain the essence of the smart grid concept we call it a concept as there is no real smart grid yet. However, there is of course more to it given the sheer complexity of electrical grids, the involved components and the many stakeholders.
Today, grid modernization has evolved to be more inclusive of customer preferences and desires. As is explained here , distributed energy resources DERs are electricity-producing resources or controllable loads that are directly connected to a local distribution system or connected to a host facility within the local distribution system.
DER systems typically use renewable energy sources, including small hydro, biomass, biogas, solar power, wind power, and geothermal power, and increasingly play an important role for the electric power distribution system Wikipedia explains. Smart grids: what is a smart electrical grid — electricity networks in evolution.
A smart grid is an electricity network enabling a two-way flow of electricity and data with digital communications technology enabling to detect, react and pro-act to changes in usage and multiple issues. Smart grids have self-healing capabilities and enable electricity customers to become active participants. The smart grid compared to traditional electricity grids — the essence and differences Smart grids: more than smart meters and advanced metering infrastructure Decentralized energy generation and the smart grid What is a smart grid?
Smart grid definitions and some challenges to address Smart grids: some additional challenges From advanced metering infrastructure to distributed energy resources.
