Abstract

In this paper, a generalized power limit of the cross wind kite energy systems is proposed. Based on the passivity property of the aerodynamic force, the available power which can be harvested by a cross wind kite is derived. For the small side slip angle case, an analytic result is calculated. Furthermore, an algorithm to calculated the real time power limit of the cross wind kites is proposed.
