Optimised power dispatch strategy for offshore wind farms

Maximising the power production of offshore wind farms using proper control strategy has become an important issue for wind farm operators. However, the power transmitted to the onshore substation is not only related to the power production of each wind turbine but also the power losses which are related to electrical system topology. This study proposed an optimised power dispatch strategy for minimising the levelised production cost of a wind farm. Particle swarm optimisation (PSO) is employed to obtain final solution for the optimisation problem. Both regular shape and irregular shape wind farm are chosen for the case study. The proposed dispatch strategy is compared with two other control strategies. The simulation results show the effectiveness of the proposed strategy.
