Evaluation of reactive power ancillary services based on objective-belt regulating and controlling method

First, based on the objective-belt regulating and controlling method proposed by reference, this paper selects 4 features and proposes a method for quantitatively evaluating shares of RPAS sources. The quantitative evaluation includes two parts that are the standard share evaluation and the actual share evaluation, and also establishes their relative indexes. Second, the paper analyzes the application of operation pattern on evaluation of RPAS, and proposes a direct classified application strategy for the same operation patterns and a modified application strategy for the variant operation patterns. These strategies not only raise utilization efficiency of evaluation results of RPAS sources for the same and similar patterns, but also ensure accuracy of evaluation results of RPAS sources for the different patterns. Last, the paper shows the rationality of the quantitative evaluation method by a real system.
