摘　　要：Due to the effects of windless and sunless weather,new power systems dominated by renewable energy sources ex-perience power supply shortages,which lead to severe electrici-ty shortages.Because of the insufficient proportion of controlla-ble thermal power in these systems,this problem must be ad-dressed from the load side.This study proposes an orderly pow-er utilization(OPU)method with load as the primary dispatch-ing object to address the problem of severe electricity shortag-es.The principles and architecture of the new urban power grid(NUPG)OPU are proposed to complete the load curtail-ment task and minimize the effects on social production and daily life.A flexible load baseline division method is proposed that considers the effects of factors such as gross domestic prod-uct,pollutant emission,and carbon emission to increase the flex-ibility and applicability of the proposed method.In addition,an NUPG OPU model based on the load baseline is proposed,in which the electric quantity balance aggregator(EQBA)serves as a regular participant in the OPU and eliminates the need for other user involvement within its capacity range.The electric quantity reserve aggregator(EQRA)functions as a supplemen-tary participant in the OPU and primarily performs the remain-ing tasks of the EQBA.The electric power balance aggregator primarily offsets the power fluctuations of the OPU.Case stud-ies demonstrate the effectiveness and superiority of the pro-posed model in ensuring the completion of the load curtailment task,enhancing the flexibility and fairness of OPUs,and im-proving the applicability of the proposed method.Index Terms-Electric power balance,electric quantity bal-ance,electricity shortage,orderly power utilization,new urban powergrid.
