Weather is no longer per-wind turbine. It's now simulated in large weather zones across the world. Therefore, wind conditions (wind speed, gusts, turbulence, direction) are persistent and consistent, and all turbines in the same area feel the same weather.
Turbines now sample the zonal weather instead of having their own simulation. They also behave more realistic, as they now feature things such as cut-outs and stable output.
Storms can now create grid disturbances that travel through wires:
These events are generated at the source (which can only be wind turbines for now) and propagate through the network, so everything downstream is affected consistently.
Power boxes now actually regulate power, react to storm events and can trip a breaer on severe conditions.
Added an event context object: PowerDeliveryEvent (surge/duration/brownout/disconnect).
