doi:10.11930/j.issn.1004-9649.2013.11.52.4

Abstract

Abstract: The intermittency and randomness of wind power brings difficulties to the decision-making of dynamic reactive power optimization. Based on the time-dependent characteristics of wind power fluctuations, the paper introduces the concept of scenario in the dynamic reactive optimization model to describe the uncertainty of wind power output, and proposes a decoupling algorithm based on sensitivity information. In the algorithm, the action time and position of capacitors and transformers are firstly determined according to their sensitivity information in every single time interval and wind farm scene. Based on the results of discrete variables, the whole model is decoupled in time and the continuous variables are then determined. Case study of 14-bus system show that the algorithm proposed in this paper is both reasonable and effective.
