A non-linear power equation may be solved in linear form by locking one or more variables and iteratively solving to accurately and quickly estimate optimized power solutions for hydroelectric power stations. Additionally, these iterative calculations may provide for long term water resource planning and more accurate estimation models. Further, such optimized power solutions may be usable to create accurate and timely water management models for the operation and planning of hydroelectric power stations.

Hydroelectric power optimization

Operation of a hydropower generation facility may be optimized by consideration and analysis of multiple factors influencing function of the facility. Aspects of the facility and surrounding hydraulic system are represented in a model that may include efficiency curves for hydropower turbines. Efficiency curves for one or more turbines are approximated by piecewise linear functions. The use of piecewise linear representations allows for calculation of recommended operational settings as well as predicted outputs in real time. An optimization system may consider input data such as weather and market prices for electricity. The input data may also include desired operational outputs of the hydropower generation facility. A user interface may present recommendations for specific operational settings to achieve the desired operational outputs.
