Maximizing wind penetration using voltage stability based methods for sizing and locating new wind farms in power system

Abstract

Current methods in which maximum sizes of new wind farms are determined do not take into consideration their impact on future wind penetration levels. In this paper, two methods are proposed to determine maximum sizes of multiple new wind farms for maximizing wind penetration levels. In both methods, each new wind farm size is determined using an iterative process where each wind farm's size is incremented by a fixed value and its impact on voltage stability margins (VSMs) is observed. Incremented wind farms which result in less negative impact on VSMs are sized larger until reaching voltage instability. Proposed methods are applied to western Kansas power system where three new wind farms are to be sized. Results of applying these new methods shows that wind penetration can be maximized by placing new larger wind farms in areas where the transmission system is strong and has high VSMs.
