There will be massive demand for vehicle charging. Smart delay will provide massive "planned consumption" - aka vehicles only charge if there is energy that is appropriate for low-priority tasks (charging EVs). V2G also consumes at appropriate moment. It just gives back when grid asks. But there are losses. And in the end discharged battery must be charged again. With losses.
V2G also offers other benefits in reducing localized strain on transmission and distribution networks, particularly during peak load events. It can potentially defer or remove the need entirely for capital equipment upgrades.
Smart delay systems do not represent a reduction or offset of load. They only represent a reduction in the impact of new load. This is beneficial but no-where near as beneficial as two-way power flows.
Smart delay will also reduce strain during peak load because there will be no load as vehicles will not consume while grid peaks.
Smart delay system will definitely offset the load to later time. That's the whole idea of smart delay. V2G ideology consumes while there is no peak (same with delay system) and discharges to grid while it peaks (on the other hand delay system stops consumption which lowers grid load).
If we exclude V2G inefficiency two paused vehicles are exactly the same as one V2G vehicle.
In real life it's something like 1,6-1,7 paused vehicles is the same as one V2G vehicle.
I would call pausing devices as PoD - Pause on Demand: Not sure but it seems it represents my idea as clearly as possible in few words.
Also this tech can be used for central heating/water heating devices. Or any other buffer-capable power hungry device.
