How to use a graph to represent wind power generation

How can a graph represent a wind farm?

Encoding relative positions of wind turbines and wind conditions into a graph We designed the graph representation of wind farm to express wake-dependent distances along the wind directions as well as positions of wind turbines as edge features. By using the graph, our model can represent any wind farm with any condition in a unified way.

How is a wind farm model based on a physics-induced graph neural network (pgnn)?

The proposed model comprises two parts: (1) representing a wind farm configuration with the current wind conditions as a graph, and (2) processing the graph input and estimating power outputs of all the wind turbines using a physics-induced graph neural network (PGNN).

How to represent interactions between turbines in a wind farm?

The proposed approach learns how to represent the interactions among turbines by optimizing the parameters θ i, i = 1,2,3,4. Furthermore, by making all update functions to share the parameters, the proposed approach generalizes well in the estimation of power outputs for various wind farm layouts and wind conditions.

Why is generating wind power scenarios important?

[Submitted on 19 Dec 2022 ( v1 ), last revised 16 Feb 2023 (this version, v2)] Generating wind power scenarios is very important for studying the impacts of multiple wind farms that are interconnected to the grid.

How many realizations are there in a wind farm graph?

For each number of wind turbines, we considered 40 realizations. The blue dot demonstrates the average execution time per one wind farm graph along the number of turbines. The blue error line indicates the standard deviations for each wind turbine cases. The light grey curve is the result of second order polynomial fitting on the execution times.

What is a wind turbine plot function?

When you run the plot function, it generates a plot of the state transitions, normalized physical quantities such as the wind speed, wind turbine rotation speed, generator power, and pitch angle. The following figure shows the model of a wind turbine.The mechanical and electrical domains each require their own Solver Configuration block.
