As the percentage of wind energy on the power grid increases, the intermittent nature of this energy source can make it difficult to keep the generation and the load balanced. While wind speed forecasts can be helpful, they can often be inaccurate. In such cases, we are interested in providing the control room operators additional relevant information they can exploit to make well informed scheduling...
The variability of wind power limits its grid penetration and increases costs. At high penetration levels, the variable output of wind requires utilities to dedicate much of their available reserve generation capacity to accommodate this variability. This paper presents research on improving wind energy integration through more effective coordination of traditional generation resources and energy...
Battery energy storage system (BESS) is to be incorporated in a wind farm to achieve constant power dispatch. The design of the BESS is based on the forecasted wind speed, and the technique assumes the distribution of the error between the forecasted and actual wind speeds is Gaussian. It is then shown that although the error between the predicted and actual wind powers can be evaluated, it is non-Gaussian...
The aim of the paper is to study the optimal participation of wind energy in adjustment markets in order to increase the wind producer revenues, through a stochastic optimization process, which considers the uncertainty of the random variables involved, namely short-term wind power prediction, intraday price prediction and imbalance price. A new modeling of the behavior of up and down imbalance prices...
The Romanian National Energy strategy is requesting that renewables quota to reach 33% of consumption in 2010 and 38% in 2020. One of the most challenging issues facing wind energy today is its maximal and reliable integration in the power markets. Due to transport/distribution grid lack of flexibility and high level of concentration in Dobrogea region of large wind developments the access to the...
Wind energy is rapidly emerging as a substantial contributor to the electricity generation capacity of utilities around the world. While the use of wind power both adds to the electricity supply and offers significant environmental benefits as a renewable source of energy, the stochastic nature of forces that produce wind energy prevents relying on it to meet base load requirements. Intermittent availability...
