This study proposes a new model for long‐term planning of large‐scale wind farms (WFs) considering voltage stability constraints. The proposed model is a multi‐objective optimisation problem which aims to maximise the profit of WF investor from wind energy procurement and to minimise the overall power generation cost. By performing modal analysis on the reduced power flow Jacobian matrix, proper locations for installation of WFs are determined. Moreover, the impact of voltage stability constraints on the capacity of WFs is investigated. In comparison with other studies, the main contributions of this study are: (i) to propose a new methodology for determination of the best locations for WFs, (ii) to study the impact of voltage stability as an important security constraint in long‐term planning of wind energy. The proposed voltage stability constrained multi‐objective wind power planning (VSC‐MOWPP) model is solved via ɛ ‐constraint method in General Algebraic Modelling System optimisation package environment. The compromise solution of Pareto optimal set is selected using fuzzy satisfying approach. The proposed VSC‐MOWPP model is examined on the IEEE 39‐bus standard test system. The numerical investigations substantiate the suitability of the proposed model for multi‐year planning of WFs at the presence of long‐term voltage stability constraints.
