Managing Wind Variability with Pumped Hydro Storage and Gas Turbines

A stochastic model for the daily coordination of pumped storage hydro plants and wind power plants

We propose a stochastic model for the daily operation scheduling of a generation system including pumped storage hydro plants and wind power plants, where the uncertainty is represented by the hourly wind power production. In order to assess the value of the stochastic modeling, we discuss two case studies: in the former the scenario tree is built so as to include both low and high wind power p...

Study on unit commitment problem considering wind power and pumped hydro energy storage

The stochastic and intermittent characteristic of wind power present great challenge to the operation of power system. A novel unit commitment problem (UCP) model is proposed in this paper. As the status of thermal units need to be described by binary number, Binary Particle Swarm Optimization (BPSO) algorithm is proposed to find the optimum schedule scheme. Case studies on the 10 units system ...

Real-time optimization of wind farms and fixed-head pumped-storage hydro-plants

In this paper we analyze whether real-time compensation of wind power plant deviation penalties is profitable by means of the coordinated optimization of the wind power plant with a pumped-storage hydro-plant. We shall make use of optimal control techniques to carry out the optimization. We shall also analyze another possible solution based on compensation carried out a posteriori, instead of i...

The contribution of wind-hydro pumped storage systems in meeting Turkey’s electric energy demand

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...
