This study presents a new methodology to determine the optimal Offshore Wind Farms connection point in a power system, with the purpose of maximising the wind power penetration, considering a Benders decomposition approach to represent the security constraints related to the ‘ N − 1 ’ contingency criterion. The proposed algorithm uses a mixed‐integer non‐linear programming approach associated with a non‐linear programming, and it is evaluated in a tutorial system (IEEE 14‐Bus) and two networks from the literature: a small case (IEEE RTS‐79), and a medium and real case (Brazilian Birds System). In each case, three points geographically close to each other are selected as candidates in the onshore grid for the wind power injection. The experiments conducted clearly show that the connection decision from the proposed approach led to the maximum safe wind power penetration among the candidate options, which proves its applicability and effectiveness, even for more complex networks, and considering all single transmission line contingencies for safe operation.
