One of my thoughts when it comes to syncing the grid was "How about generating DC power and then using true sine inverters controlled through the grid to convert from DC to AC and then feed that to the places it's needed"... After a quick chat with an engineer at Drax power station it turns out it would be extremely expensive, you'd be wasting power in the inverters for current conversion and it adds an extra point of failure*, so while it would be easier to synchronise the grid to a specific frequency, it wouldn't be as reliable as synchronising all power stations to dump just the right amount of power at the right frequency just as we need it.<br><br><br><br>*When I say "An" extra point of failure, I'm seriously underselling it! there are multiple chances for an inverter to blow out, multiply that with an entire power grid and you're just asking for something to go tits up!
