Study Notes

Smart Grid Technologies

  • Advanced sensors, communication systems, and data analytics were introduced to enhance grid efficiency, reliability, and sustainability.
  • Decentralization and microgrids allow for localized generation, consumption, and storage of electricity.
  • Energy storage technologies, such as advanced batteries, manage intermittent renewable energy sources.

Smart Grids and Digitalization

  • Smart grid technologies continue to evolve, leveraging digitalization, real-time data analytics, and two-way communication between utilities and end-users.
  • Focus areas include:
    • Enhancing grid resilience
    • Accommodating electric vehicles
    • Improving energy efficiency
    • Enabling greater integration of distributed energy resources

Motives behind Smart Grid

  • Solving problems related to:
    • Growing energy consumption
    • Integration of distributed generation
    • Energy efficiency
    • Power supply reliability
    • Power quality

Definition of Smart Grid

  • According to the European Technology Platform: "A Smart Grid is an electricity network that can intelligently integrate the actions of all users connected to it – generators, consumers and those that do both – in order to efficiently deliver sustainable, economic and secure electricity supplies."
  • According to the US Department of Energy: "A smart grid uses digital technology to improve reliability, security, and efficiency (both economic and energy) of the electric system from large generation, through the delivery systems to electricity consumers and a growing number of distributed generation and storage resources."

Characteristics and Benefits of Smart Grid

  • Flexible: designed to fulfill customers' needs and respond to changes and challenges.
  • Accessible: grants connection access to all network users, particularly for renewable power sources and high-efficiency local generation.
  • Reliable: ensures and improves security and quality of supply, with resilience to hazards and uncertainties.
