As explosive growth of wind power, a large number of reactive power compensation methods and control strategies are proposed in grid of wind power focus area. However, how to evaluate its effectiveness and select the best reactive power compensation method is needed to solve problem. Aiming at the above, a novel method, evaluation method of multiple wind farms based on survival exponential entropy, is proposed to evaluate reactive power compensation strategies from voltage quality and economy. By using example of the multiple wind farms in regional grid, four different reactive power compensation strategies are evaluated. Theoretical analysis and experimental results show that the proposed method is available and effective.
