Smart Grids

Smart grid is a developing network of transmission lines, equipment, controls and new technologies, working together to respond immediately to the current demand for electricity.

Current grids have a one way interaction are not adapted and make it hard to response to the changing and rising current energy demands. The smart grid introduces a 2 way dialogue where electricity and information can be exchanged between a utility and its customers, developing network of communications, controls, computers, automations and new technologies and tools to make the grid more efficient, reliable, secure and greener.

It is important, to create a metrology infrastructure to monitor stability and quality of supply of Smart Grids in order to support their effective development and implementation.

Renewable resources are a sustainable and growing source for electric power, however, renewable power sources are variable by nature and add complexity to normal grid operations. Smart Grid provides the data and automation needed to enable solar panels and wind farms to put energy onto the grid and optimize its use.

To keep up with constantly changing energy demands, utilities must turn power plants on and off depending on the amount of power needed at certain times of the day. The cost to deliver power depends on the time of the day used. Electricity is more costly to deliver at peak times, as additional often less efficient power plants must be run to meet the higher demand.

Smart grid will enable utilities to moderate and manage electricity usage, with the cooperation of its customers especially during peak demand times as a result utilities will be able to reduce their cost by differing electricity usage away from peak hours, electricity production is more evenly distributed throughout the day.

Key Points
Metrological strategies used for cost-effective optimized measurement and control of smart grids.
Analysis of smart grids to enable operators to develop effective measurement strategies.
Reliable and accurate Phasor Measurement Units (PMUs), a key tool for monitoring stability of smart grids.
Important to assure power is measured accurately with standards for electric power measurements.
Small grid enables new technologies to be integrated, such as wind, solar energy production or electrical car charging.
Small grid will replace the existing infrastructure of today’s grid and utilities can better communicate  to help manage electricity needs. Utilities can provide its customers with much more information to manage their energy usage and or bills.
Smart grid technologies provide detailed information that enables grid operators to see and manage electricity consumption in real time to more precisely and predictably manage electricity consumption. .
Distribution intelligence trough power lines, switches and transformers.
