A smart grid is a form of electricity network using digital technology. A smart grid delivers electricity from suppliers to consumers using two-way digital communications to control appliances at consumers' homes; this could save energy, reduce costs and increase reliability and transparency if the risks inherent in executing massive information technology projects are avoided. The "Smart Grid" is envisioned to overlay the ordinary electrical grid with an information and net metering system, that includes smart meters. Wikipedia
The move toward more competitive electrical power markets is envisioned to enable consumer choice and dollar votes in terms of price, power quality, and fuels used to generate power.
They draw power at a rate of 1.4-2KW which is easily supplied by standard home wiring. Note that a standard 20A, 120V socket is 2.4KW.
In order for the ElectriNetSM to be realized the following attributes are needed;
Capgemini’s Vision (www.capgemini.com/energy): Focus should be on 4 main activities:
1. Gather Data: from many sources on the grid.
2. Analysis / forecasting: the data for operational and business purposes.
3. Monitor / Manage / act: an operational system that triggers predefined procedures that log or take action.
4. Rebuild the grid to support bi-directional power flow.
IntelliGridSM (www.epri-intelligrid.com): A consortium created by EPRI to pave the way to the IntelliGridSM. Partners are utilities, manufacturers, and representatives of the public.
Objective: greater consumer choice and rapid advances in communications, computing, and electronics are promoting similar changes in the power industry. A growing knowledge-based economy requires a digital power delivery system that links information technology with energy delivery.
The Modern Grid Strategy ( electricity and an increase in the efficiency of the power delivery system and in the efficiency and effectiveness of end users.www.netl.doe.gov): The U.S. Department of Energy (DOE) National Energy Technology Lab (NETL) is the manager of the Modern Grid Strategy (MGS). There function is to foster a national vision for the grid among all stakeholders. p19
UK SuperGen Initiative (www.supergen-networks.org.uk): A consortium that has recognized two broad challenges: First, there are engineering problems created by embedding renewable energy sources into a distribution network and second there is a need to develop a market and regulatory environment to encourage the use of renewables.
The Galvin Initiative (www.galvinpower.org): Inspired and sponsored by Robert Galvin (former CEO of Motorola). Wants to achieve a consumer focused power system that never fails.
Electricite de France (EDF) Power-Strada electricity and an increase in the efficiency of the power delivery system and in the efficiency and effectiveness of end users.: EDF proposes to “invent the smart grid”. It defines it as integrating distributed energy resources with dispersed intelligence and advanced automation. p23
The electric grid was designed and built using technology of the 40’s and 50’s. It has since been expanded but not modernized much. Applying modern technology will improve its efficiency and function.
