hydropower station energy storage prediction analysis

Why do hydropower stations need a prediction method?

The prediction method improves the waiting time for ships to pass through the lock and it also improves the power scheduling effectiveness of hydropower stations. When the power generation of a hydropower station is greater than the demand of the grid, the energy storage is ready to store energy.

Can a scheduling strategy stabilize the power generation of hydropower stations?

We propose a scheduling strategy that considers the real-time passage of ships and the use of energy storage to stabilize the power generation of hydropower stations. The strategy is applied to a real case of the Silin Hydropower Station on the Wujiang waterway in China to show the effectiveness of the proposed solution.

How accurate are transient processes for pumped-storage hydropower stations?

Achieving accurate predictions of transient processes for pumped-storage hydropower stations (PSHSs) remains a key challenge due to uncertainties in on-site parameters, particularly the pump-turbine characteristic curves (PTCCs), and limitations of the physics-based models themselves.

What are the data related to the scheduling of a hydropower station?

The data related to the scheduling of the hydropower station are the lower limit of downstream flow (i.e., \ (Flow\_down\)), the upper limit of downstream flow (i.e., \ (Flow\_up\)), the grid load demand (i.e., Load), the ship passage (1 if there is a value otherwise 0), the guaranteed rate of navigation k, and the head H.

Are hydropower stations integrated into the power grid system?

This paper focuses on the research of hydropower stations integrated into the power grid system, considering the functions of navigation and power generation. We propose a scheduling strategy that considers the real-time passage of ships and the use of energy storage to stabilize the power generation of hydropower stations.

Can a hydropower model predict daily energy production?

It would be interesting, in our opinion, to develop a short-to-medium term hydropower model that uses both mathematical optimization and machine learning algorithms to predict daily energy production while also monitoring reservoir level and water inflows.

In this study, artificial neural network algorithms (RNN and LSTM) are used to predict the condition of the hydropower station, identify the fault before it occurs, and avoid it. After testing, the LSTM algorithm achieved the greatest results with regard to the highest accuracy and least error.
