This paper proposes a simulation framework for assessing the possibility of wind power plant integration into the existing transmission network in an optimal manner that takes into account the wind potential at each location scheduled for WPP construction. Wind power plant capacity allocation is analyzed from the static aspect considering maximum line loading under normal system operating conditions with WPP production modeled as stochastic variable. Primal-dual interior point method with a preprocessing phase which eliminates redundant constraints is employed to solve the optimization problem.
