Abstract [en]

A key issue in the construction of grid-friendly offshore wind farm is how to reasonably achieve the optimal allocation of active power of each unit so as to improve the safety and grid power of the wind farm. This paper proposes a novel distributed control strategy for cooperative optimization active power output on the basis of the deficiencies of the traditional distribution strategies. A simple type division algorithm is proposed to solve offshore wind farm dispatch problem. The principle of division is in accordance with the actual conditions and power characteristics of the wind turbine. Secondly, we propose a distributed coordinated control scheme based on ratio consensus algorithm for two types of wind turbines. This algorithm is stem from distributed average consensus for undirected graph. Ratio consensus is guaranteed by updating the auxiliary variables state values with the step size of the distributed consensus algorithm is chosen appropriately. Simulation examples show the effectiveness of these design methods.
