In this paper, a new robust controller has been proposed for attaining the maximum safe instantaneous wind penetration. Particle swarm optimisation (PSO)-based algorithm has been developed to obtain the maximum safe instantaneous penetration by the optimisation of grid parameters. The developed algorithm has been tested on modified IEEE 14-bus system. The effectiveness of the proposed methodology has been shown in terms of maximum instantaneous safe wind energy penetration limit, in percentage and also maximum safe bus loading point, explicitly beyond which system drives into instability.
