smart-grid-iec-61850-compatibleAn electrical grid is not a single entity, but a collection of multiple networks and multiple power generation companies, with multiple operators employing varying levels of communication and coordination.

Mostly this is manually controlled or a semi autonomous system employed with numerous systems communicating but not with each other. Smart grids increase the connectivity, automation and organisation between these suppliers, consumers and networks. This means that all devices on the smart grid will be able to communicate adding further control and ease of monitoring.

Conventional Power Plants generate power relatively continuously. The feed in performance of distributed generators and power from renewable sources are continually fluctuating as they depend upon a number of ranging factors. Solar power for instance from photovoltaic systems, is only available when the sun is shining and wind farms can easily produce more power than is needed when winds are strong. A smart grid is able to manage these variations in power to integrate all generators in to the grid.

With on going research and development of the latest in smart grid technology British Research is able to offer your organisation the knowledge and expertise needed to implement a smart grid. Our dedicated team are also able to provide training so that your employees understand the latest technology and its uses within smart grids.

The components of a Smart Grid consist of:

Hardware

  • Sensors, Embedded processors, Intelligent Electronic Devices (IEDs)
  • Integration with other hardware, legacy systems and power systems components.

Software

  • SCADA, Energy management, information management

Communications

  • Slow / legacy systems (existing SCADA ) Vs High-speed, high-bandwidth (Based around TCP/IP and Ethernet to standards such as IEC61850 for substation automation)

Transmission Applications

  • Grid integration of renewables,
  • Advanced metering (AMR / AMI), operations
  • Emergency control; Load shedding, Intelligent system separation

Distribution Applications

  • AMI – Application of smart meters
  • Real-time pricing
  • Demand side management
  • Distribution automation
  • Optimising efficiency, reliability, carbon footprint

On Customer Side of Meter

  • Load Management (coordinated w/utility)
  • Integration of energy resources as micro-grid
  • Interconnection with Utility
  • Interruptible Loads (water heater, heat, AC)
  • Electric or hybrid-electric vehicle
  • Generation: solar, wind, micro-hydro
  • Energy storage: battery
  • Optimal control according to goal of customer

Requirements & Concerns

  • Communications bandwidth for “fast” wide area applications
  • Interoperability
  • Cyber security
  • Information security, privacy
  • Complexity, reliability of technology & applications.
