要約(英語): This paper proposes a novel method to assess the performance of the automatic generation control (AGC) in a steady state of a power system. As the penetration of solar and wind power generation increases, the frequency control of a power system faces a challenge because the increase causes more fluctuations and forecasting errors in generation output to be dealt with the control. The improvement of AGC systems is thus indispensable in the future power systems. This paper proposes a method to evaluate the performance of the AGC with new indicators―control delay angle and control performance angle. After examining the angles evaluated with the standard deviations of the fluctuations of demand, generation output and control error, the paper proposes to extend them to a frequency domain using spectral analysis techniques. The control performance angle defined in the paper can assess the optimality of the control. The proposed method is applied to simulation results of the standard model of IEE, Japan for AGC studies. The results show that excessive control in AGC deteriorates the performance of AGC when thermal power plants with a steam turbine are used for load frequency control.
