"The Future is out there somewhere; we just have to make sure we get the best one"
"There are an infinite number of ways of running an Electricity Supply system badly"
The way in which electricity is to be supplied is subject to radical change. Distributed and Renewable Generation, together with Demand Management, is being promoted to reduce the use of central fossil fired plant, increase efficiency in delivery of energy and reduce emissions.
However, this will only be achieved if all resources are properly monitored and controlled within a new framework for electricity supply management. Any electricity supply system is always in instantaneous Power balance; the wires hold no storage and electricity moves at the speed of light from Alternator to Appliance across the system. We need to recognise the need for continuous tight matching of generation power to demand power and the associated requirement for accurate prediction. Both power and time are crucial factors.
When the GB System Demand Peaks at 52GW, we are pushing @65 million Brakehorsepower through a quite fragile set of wires. Each AC system is a giant interlocked machine.
The future system, comprising Central Generation (Big) and Distributed Resources (Little), needs to work as a disaggregated but co-ordinated unit to make major improvements. This is a combination of the Wholesale (Big) and Retail (Little) Markets, with System Operator functions, to reduce the output requirement from fossil fired main plant while at the same time making sure the remaining output of such plant is generated at the most efficient level (full load). This will ensure an effective reduction in fuel burn and emissions.

All in all what we require is not just a ‘Smart Grid’ but a ‘Smart Enterprise’.
There you will also find a link to my 22 articles on Future Power Systems
FPS 1-3 look at the basics of matching and generating plant characteristics. FPS 1 now has a Gas Power demand diagram which shows the awesome level of storage they have, as against Electricity which has none.
FPS 4 covers renewables impact and has a new diagram to show the effect of forecasting uncertainty on the big ramps caused by wind variability (Page 7). This is crucial to demonstrate that these movements are much more difficult (if not impossible) to handle than the regular demand ramps.
FPS 5-7 tackle future distribution (esp active), FPS8-14 the customer to utility interface while FPS15-19 examine customer data and participation issues.
The potential for storage and the ability of ICT to provide effective monitoring and trading/control of distributed resources (DER - covers customer demand, generation and storage) and maintain network security is covered here.
FPS 20 looks at the Smart Enterprise as regards Objective (flatten the fossils) and Forecasting impact (existing Top-Down methods rendered useless)
In FPS 21 I go through Customer Engagement in some detail where I develop a proposal for 'empathic constructive dialogue' and a staged approach to introducing more dynamic pricing. Go to the end first to see the salient points.
Finally, FPS 22 asks the big question; what is the value of each Future Electricity and Future Energy strategy.
