A hydrogenerator’s cost price is considerably influenced by the used and computed design values. The most important parameters in the design of micro hydro power plants synchronous generators are the power blanket, the current density in the statoric winding and the air gap size. In this work we analyze the impact of these parameters on the cost price for a family of hydro power plant synchrono...

A coordinated strategy between wind and reversible hydro units for the mid-term that reduces the imbalance of wind power and improves system efficiency is proposed. A stochastic mixed integer linear model is used, which maximizes the joint profit of wind and hydro energies and Conditional Value at Risk (CVaR), where CVaR is the tool utilized to model risk. The offering strategies studied are: i...

This paper presents a new approach to Load Frequency Control (LFC) for a hydro-power plant. The control algorithm combines sliding mode control with H∞ technique. The dynamic model of an entire hydro-power plant has been developed. The sliding hyperplane is constructed by H∞ full state feedback control method. The ideal lossless turbine-penstock model is used in this paper to conduct the simula...

Renewable energy resources have played an important role to meet increasing energy demand in the world. Among the renewable energy resources, especially, wind energy is of interest due to some advantages, such as being clean, environmental friendly etc. However, the intermittent nature of wind creates several problems to the power system operation and new approaches based on the combined use of...

This paper presents a new optimization algorithm to design an optimal proportional, integral, derivative (PID) controller in hydro-turbine generator governor for damping output frequency oscillations. In this research, we utilize a stochastic and optimal based PID controller to control frequency-response of the hydro turbine. The proposed algorithm is employed to design an optimal PID controlle...

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...

This paper presents generic model of hybrid power system consisting in a combined solution one wind turbine with asynchronous generator and on hydro generator with synchronous machine. This technology was developed by to reduce the cost of supplying electricity in remote communities. The optimal wind penetration (installed wind capacity/peak electrical demand) for this system depends on the sit...
