How are power ramp events classified in the paper?

The paper presents two new methods for ramp event classification. The first method depends on the standard deviation score, and the second method assigns a score to each ramp, which depends on the maximum value of the historical power ramps that occurred within the studied time period.

Is there a definition of ramp events in wind generation data?

So far, there is no agreement on an accepted definition or categorization for the power ramps in wind generation data. The identification of ramp events in historical wind generation data over many years is a statistical challenge, as there are no proven criteria for the concept of ramps.

How are ramp events classified?

The other studies were based on an arbitrary classification of ramp events, in which a randomized and non-causative classification was used to classify ramp events into several levels. As a result of this heterogeneity in the classification of ramp events, a unified framework for solving this complexity is required.

What is the RIF of a power ramp?

The classification results of the second proposed technique for upward and downward power ramps show that the RIF of the majority of power ramps in the 5 years is less than 0.3.

Should grid operators classify power ramps?

Grid operators should classify power ramps to understand their expected occurrence periods and range to balance them. Previous research was based on a binary classification of ramp events, which assumed that ramp events were similar to one another, which is not true.

How important is the prediction of ramp events in wind power?

Predicting severe upward or downward ramp events in wind power is very important to ensure the security and reliability of a system. The control actions differ according to the range, not the exact value, of the ramp event.
