The economic value of forecasts for optimal curtailment strategies to comply with ramp rate rules

We present a method to calculate the economic value of forecasts, based on the use of forecasts to optimize curtailment strategies in scenarios with a ramp rate rule. We consider how and when to limit PV power output in order to comply with a ramp rate rule to avoid penalties, but also calculate how curtailment will reduce revenue from energy yields. This framework provides a way to assess the value of forecasts.
