How to minimise high magnetic field strength for a SMART GRID?

[ManUnited1]

I wanted to know some measures that would allow the SMART GRID to operate safely and normally.

Define 'smart grid'.

"Smart grid" - the mess that results when politicians with zero engineering experience attempt to "improve" existing electrical infrastructure.

You could locate the SMART GRID far away from any sources of electrical power.

Or wrap it in aluminum foil.

I like the definition of smart grid above. Those definition can be supplement with other definitions such as

“a smart grid is the electricity delivery system (from point of generation to point of consumption) integrated with communications and information technology”

Smart grid system could be delivered safe. However, we should expect a great deal of complexity in exchange of higher efficiency.

I'm just struggling to see how improvements in comms and protection would reduce the magnetic field due to the conductors. I do have an amusing image of wrapping the conductors in politicians and bureaucrats though.

The idea of moving the SMART GRID sounds reasonable but what if it cant be moved. Covering the electronics seems to be the only other option available.

Smart Grid will be the means, unfortunately for the consumer, by which electricity can be rationed, tariff-adjusted (on the fly), or even cut off (IGBT switch in the meter)at the pleasure of the supplier.

A golden market-opportunity for new organizations (not yet existing)similar to those now monopolizing internet services, as well as operating systems, which we have to depend on to survive.

You might be buying your power from the "big M", the local supermarket chain, or similar orgs in the future. If something goes wrong with your account, you might return home one day to a blacked-out house or apartment...We all know, by this time, how less-than-reliable anything involving computers is.

A beautiful tool in the hands of the wrong type of people.

There is no known link between intelligence and magnetic flux density.

Regarding "normally":

I think there is a plan to design the system so that it will operate normally, except during abnormal operations.

(Sorry, I couldn't resist)

There is not doubt that fast communication combine with power electronic devices and other conventional hardware for voltage support and regulation such as SVC, STATCOM, series and shunt compensation, etc assisted with electronic switching devices wil optimize the power flow, minimize losses and increase the system reliability.

There is a potential concerns associated with the control system of multiple devices interconnected in the same network that may conflicting to respond properly to a particular disturbance event

"Smart Grid" has many different components some of which will increase, decrease or time shift magnetic fields. If that relates to safety is a whole different question.

1. More efficient use of the existing transmission grid:
*more power flowing through existing transmission lines causes higher magnetic fields on existing lines
*zero magnetic fields on avoided transmission lines.

2. Integration of renewable resources:
*Wind resources are often distant from loads while solar ones may be closer

3 Load shaping, storage and electric car charging:
* These all increase the amount of electricity that must be transmitted, trading high peak currents for a overall higher average current.

4 Higher reliability:
Faster restoration and less outages obviously means more exposure. The EPRI predicted 20% reliability improvement by 2025 would increase my uptime from 8759 hours per year to 8759.18 hours per year.

5 Integration of distributed generation:
*Lowers magnetic fields and moves air pollution (if any) closer to the consumer.
