You need to ask the PoCo how they would handle that....SM's can't throttle voltage or create brownouts. In S&B homes large draw appliances like a/c and water heater can be fitted with relays so the PoCo can shut them down during peak demand.
In your case I would think the 2 options are to shut your power off, or raise the kWh rate when you exceed the limit. 7000w is only about 60a, so with 3 a/c's going and maybe a HW heater or microwave, you are almost there.
Interesting article about smart meter's in the PNW.FWIW, those pole transformers are like roman candles when they blow, hope it's far enough down the road where it can't get your rubber roof....
