Wind farm output power fluctuations both in short-term and long-term, create adverse effects on the voltage, frequency, and transient stability of the utility grid. In this paper, integration of wind energy with long-term energy storage devices to support the long-term and short-term shortcomings is discussed. Specifically, the energy storage is used for power ramp rate control, power smoothing, and...
Nowadays, horizontal axis wind turbines (HAWT) do not work continuously, as they don't work about 20% of the yearly period, due to low wind velocity conditions. In this present paper this problem is addressed by analyzing a wind farm and a vertical axis wind turbine (VAWT) with a wind concentrator. Results proved that the electric energy production of HAWTs could be improved if they are combined with...
This paper reviews main forecasting techniques used for power system applications. Available forecasting techniques have been discussed with focus on electricity load and price forecasting as well as wind power prediction. Forecasting problems have been classified based on time frame, application specific area and forecasting techniques. Appropriate examples based on data pertaining to the Victorian...
This paper present a novel method for matching the wind farm with wind turbine generating units from the view point of site data and generator parameters. The paper focuses on selecting wind generator turbine parameters' in order to optimize the generated energy while maximizing the utilization of the wind power available at the location. The study presents an improvement to the site performance by...
This paper addresses the problem of predicting a wind farm's power generation when no or few statistical data is available. The study is based on a time-series wind speed model and on a simple dynamic model of a DFIG wind turbine including cut-off and cut-in behaviours. The wind turbine is modeled as a stochastic hybrid system with three operation modes. Numerical results, obtained using Monte-Carlo...
