Do they shut down whole production? It looks like the setup is lacking simple PID with slowing down the turbines (by rotating blades of course) or shutting down only part of it?
Maybe I lack some of the context here, but that's the first thought.
- p_l 1y agoActual execution of curtailment depends on mechanism of individual turbine and various support equipment at provider. Essentially the "electricity market" is putting out orders for increasing or decreasing production (plus various auxilliary services, like frequency stabilisation), and production companies use often pretty complex mechanisms to both bid and trade them dynamically. It goes from somewhat large portions traded day ahead, to even minute by minute adjustments, and the actual pricing/trading etc. involves details like "how fast can you deliver/reduce the energy". Some double-fed generator turbines carefully manage waveforms generated into excitation coils to very dynamically adjust power flows, some use permanent magnets and pretty beefy inverters. Some can even provide dynamic reactive sinks in case of big load falling off the grid.
