In order to solve the problem of reliability and flexibility of new power system with uncertainty on both sides of the source and load

taking reserve market as research object

considering coordination and complementarity characteristics of multiple types of energy sources in source-network-load-storage and impact of electricity price on reserve cost during peak and valley periods

a time series double layer reserve optimization strategy is proposed that considers the response prioritization of source-network-load-storage multi-standby with standby operating costs

response time

and carbon emissions as optimization objectives. Firstly

operation characteristics of each reserve body of source- network-load-storage are analyzed and mathematical models are established. Then

a two-layer optimization model for source-network-load-storage multi-reserve coordination with multiple optimization objectives is built. Hierarchical analysis is used in the inner layer to compute the temporal response order factor of unit-capacity multi-reserve under different optimization objective ratios. The optimal ratio of the multi-optimization objective is searched and the standby capacity optimal allocation of source-network-load-storage multi-reserve for different time periods. Finally

Power grid in a province is used as an experimental example for simulation verification

and the results show that the proposed method can effectively reduce reserve cost

response time and carbon emissions.
