摘要：

It is hard to comprehensively and objectively evaluate the operation security of wind farms by single index, for this reason, based on variation coefficient method and technique for order preference by similarity to an ideal solution (TOPSIS) a comprehensive evaluation method for operation security of wind farms is proposed. Firstly, the variation coefficient method is used to calculate corresponding weights of all indices; secondly, the relative approach degree of each wind farm from corresponding sample point and the optimal sample point is calculated by TOPSIS, and then through the ranking of the calculated relative approach degree the comprehensive evaluation rank of wind farms is implemented. The high/low frequency ride through ability, low voltage ride through ability, voltage deviation at grid-connected point, dynamic response performance of SVC/SVG, active power control ability and power loss are chosen as evaluation indices for wind farms. Finally, taking the comprehensive operation security evaluation of wind farms located at a certain region as the case, the effectiveness and the feasibility of the proposed comprehensive evaluation method for wind farms are validated.
