Wind power penetration to power systems is increasing rapidly in the recent years due to its environmental benefit, while wind power fluctuation also brings some problems to power system operation which impacts the transmission company's willingness to accept wind power. The most serious conflict influencing wind power development is that the currently adopted price of wind power on-grid does not...
Wind power forecasting has great significance to the connection of wind farms to the electric power system. This paper analyzes individual forecast models, such as the time series forecasting, Elman network forecasting that based on the chaos theory, grey neural network forecasting, and generalized regression neural network forecasting, etc., then puts forward an entropy weight combination prediction...
With the capacity increasing of single wind turbine and the size of wind farm, the generation reliability issues of wind farms become increasingly prominent. Compared with conventional power supply, wind power has strong stochastic volatility. Then the reliability evaluation indices for conventional supply are not suit for wind power. So it is more and more important to research and development the...
Wind energy is the most important type of renewable energy in Europe. The stability of system network operation with a large penetration of wind energy has become one of the most critical issues in the new structure of power systems with different types of generation. In this paper the HVDC and HVAC connection of the wind farm to grid is compared. The HVDC is more advantageous in maintaining the system...
This paper deals with the aspects of stability assessment for the VSC HVDC transmission systems that are especially relevant for this technology when applied on a large scale. It focuses on the control strategies for the VSC HVDC transmission necessary to reach a full integration of large offshore wind farms into the power system operation while minimizing the critical situations for the power system...
