This paper introduces the real-time coordination of wind and hydro power plants in case a part Croatian Power System where hydro–wind is represented by Vrataruša farm Senj Vinodol hydropower plants. The model uses real data which represent generation units that make system. Also, describes general problem specific for these type energy sources. For modeling hydro-wind coordinated generation, MA...

Recently, electrical power consumption has been expected to be growing within the upcoming decades driving by high demand and rise of population. Currently, major concern related used energy resources is poor sustainability depletion for fossil fuel which represent main source generation. Therefore, need increase use optimize renewable systems have become greater than ever. In Malaysia, hydro a...

In this work a response surface approach was used for predicting the hill chart of a small horizontal shaft Kaplan turbine. To this aim, artificial neural networks (ANN) were chosen as a fast, reliable, and computationally inexpensive tool. The training of the ANN was based on computational fluid dynamics (CFD). The optimization of the runner-guide vane stagger correlation is a time consuming a...

Historically, the optimal production of hydro power plants was determined once day ahead. Today, many regulatory requirements in the German electricity market make this process much more complex: Power plant operators are committed to report information on planned production and even on provision of balancing energy of each single generator to transmission system operators. As soon as a deviati...
