Abstract:In order to overcome the problem of the lagging control within the conventional automatic generation control (AGC) and improve the adaptability of the interconnected power system to the new control performance standard (CPS),the dynamic optimization model for AGC generators dispatch has been proposed.However,the existing model still have some defects,such as neglecting the effect of network security constraints and power loss,etc.An extended dynamic optimization model for AGC generators dispatch under CPS is thus proposed in this paper with the following modifications:①the active power loss and the loading limits through the branches and boundaries are integrated;②the original objective of ancillary service cost is revised;and ③the completion of electricity production contract is added as a new objective function.The modified IEEE 14-bus test system is used to verify the extended model and the physical interpretations of treating the CPS1 index as an objective and/or a constraint are also discussed.
