In this paper

a set of such four-level performance system evaluation performance as whole grid performance

station performance

operation evaluation performance and strategy evaluation performance are proposed on the basis of AVC control strategy of certain region. The performance is calculated based on the control strategy given by grid operation data and its AVC system of certain region. For the convenient comparison in this paper

comprehensive fuzzy evaluation method is adopted for evaluation of individual AVC control strategy and operation of AVC within a definite period and the evaluation grade is given. The system can display grade of individual performance for the convenience of analyzing the advantage and disadvantage of the control strategy. It is proved by the calculation that the evaluation system has a high reliability.
