[QUOTE="TechWise, post: 7862730, member: 11384"] The way the power network operates is going to undergo quite radical change over the next few years, in fact, it's already underway. National Grid are the Transmission System Operator (TSO) who have historically always been in charge of matching generation and demand, as well as controlling the system to remain within specified voltage and frequency limits and ensuring it's always configured to survive faults. In fact, the issue of total generation vs total demand is often the least of the concerns. This model has always worked well where, as [USER=6937]@Hampton[/USER] points out, the generation was centralised at a few large stations, usually close to a coal field, and the demand was spread out. You could basically assume a trickle-down system where if you pushed power into the 400kV system, it would eventually trickle down through the transmission system then into the distribution system and all the way down to 230V for individual houses. For that reason, the distribution network operator (DNO), who takes over from 132kV down to 230V, had no control over the network, other than being allowed to switch bits on and off for maintenance. Fast forward to now, the large coal fired stations are going offline and generation is popping up everywhere. That essentially flips the system on its head, where you're pushing power into the low voltage system at 230V then feeding it back up into the transmission system. At the moment, the plan is to change the way the network is regulated by giving the DNOs control over their "patches", leaving it up to them to match generation and demand locally to a certain extent.
