The high penetration of wind power plants (VE) in the power system can be accelerated by prudent use of existing transmission capacities and optimal selection of locations for the construction of VE. In this paper, a simulation framework is proposed for determining the possibility of integrating VE into the existing transmission network in an optimal way that takes into account the quality of the wind potential at each of the locations planned for the construction of the wind power plant. The methodology is based on a scenario analysis (from the aspect of consumption in the system and production of other classic power plants), which means that for each characteristic operating condition, or more, the optimal amounts of installed power of VE are determined for each of the locations. In relation to the current practice, the method brings certain improvements, mainly in terms of probabilistic analysis, which is manifested through stochastic modeling of VE production.
