Fast Calculation of Probabilistic Available Transfer Capability Considering Correlation in Wind Power Integrated Systems
摘要
Abstract
Wind power integration has made a new demand on the calculation of available transfer capability (ATC) in power system operation. How to accurately evaluate ATC considering the stochastic variation and spatial correlation of uncertainties as well as improve the calculation efficiency has become an urgent problem to be solved. A new fast calculation method for probabilistic ATC with the presence of wind farms was proposed. The method used Latin hypercube sampling to improve the sampling efficiency, combined with Cholesky decomposition to involve the correlation of input random variables into the ATC problem. Based on clustering algorithm and modern interior method, optimal power flow sensitivity was proposed to compute the ATC values for all sampled scenarios at a fast speed. The case studies in IEEE-RTS79 show that the proposed method can reduce the computation time and ensures its accuracy. The results also verify the strong correlation of wind speed can enhance the fluctuation of ATC, which needs to be considered in the calculation.关键词
