Optimization of Active Power Dispatching Considering Lifetime Fatigue Load for Offshore Wind Farm Based on Multi-agent System

As a rapidly developing renewable energy source, effective active power dispatching for wind power has become common. For offshore wind farms with high maintenance costs, balanced fatigue loads among wind turbines need to be considered in order to reduce the number of maintenances. Based on this target, this paper proposes an optimized power distribution function to balance the fatigue difference among wind turbines. At the same time, this paper adopts the structure of the unsupervised multi-agent system (MAS) in the offshore wind farm, the communication between wind turbines is used to complete the allocation of power commands. The simulation results show that the wind farm with MAS structure can effectively deliver the power commands. And the optimized power distribution function can reduce the fatigue difference of the wind turbines after longterm operation.
