A New Evaluation Method for AGC Units ’ Performance

In this paper, a new method for evaluating AGC generators performance was developed. At first, the control performance assignment of the control area was given, which makes use of the correlation coefficient about the frequency error and the generation difference between total generation and the scheduling generation in control area as the control performance index, and the standard deviation of system frequency as judging standard. The control performance assignment is consistent with current control performance standards, such as CPS. And then according every generator´s distribution coefficient in automatic generation control, the control performance assignment was allotted to each generator, and it means the AGC generator´s performance standard. At last, when the generating command exceeded the AGC unit declaring scope, a compensatory correcting method was discussed. The theory analysis and simulation results are presented in this paper. The results validate the presented method´s correctness
