Introduction

Smart grids are electricity networks that use digital technologies, sensors and software to better match electricity supply and demand in real time. They coordinate the needs and capabilities of all generators, grid operators, end users and electricity market players to operate all parts of the system as efficiently as possible. In doing so, they minimise costs and environmental impacts while maximising system reliability, resilience, flexibility and stability of the grid.[1]

Key Features of Smart Grids /Technologies and Appliances

  • Digital Communication
  • Advanced Metering Infrastructure (AMI)
  • Smart meters and measurement systems
  • Grid Automation and Control
  • Power system automation
  • Distribution Automation
  • Advanced Electricity Pricing

Challenges and Opportunities of Smart Grids

Grid security / Cyberattacks

Smart grid technologies can both increase and decrease grid security. For example, advanced grid monitoring can detect grid problems (such as transmission line failure) early and help make appropriate changes ( by shifting loads to other lines), thereby increasing grid security. On the other hand, smart grids also bring new challenges, as they are vulnerable to cyber attacks.[2] These risks need to be adequately adressed , which is not always the case.[3]
