Timeseries models

Farm performance is analysed by cross-comparison of 4 timeseries models.

Turbine production

SCADA production, including loss estimates due to gaps, stops and partial-performance periods.

Metrics: Energy (full performance), Freestream production (100% availability), Full-performance slots, Out-of-environmental-spec loss, Partial-performance loss, Production, Production (100% availability), Stopped loss

Tipspeed optimized

Tipspeed expected production for the optimized farm, at 100% availability.

Metrics: Expected (optimized, 100% avail.), Expected energy (full performance)

Tipspeed actual

Tipspeed expected production given current farm performance, at 100% availability.

Metrics: Freestream (current period), Gross (current period), Wakes loss (current period), Yaw misalignment loss (current period)

Tipspeed long-term

Tipspeed expected production for an optimized farm, given a climate representative of the long term conditions.

Metrics: Freestream (representative period), Gross (representative period), Wakes loss (representative period), Yaw misalignment loss (representative period)
