As the construction of new energy systems accelerates,optimizing demand response mechanisms to ensure efficient market-oriented operation is crucial for deepening the management of the demand side in electricity systems.To address the issue of low response reliability in demand-side resources participating in grid interaction,a strategy for the active and passive combined response of demand-side resources considering response reliability is proposed.Initially,a combined response mechanism for active and passive response resources is established,guiding demand-side resources to make reasonable bids based on their characteristics and grid requirements.Subsequently,a model for the active and passive combined response of demand-side resources considering response reliability is developed.This includes an optimization method for the grid demand adjustment coefficient based on the binary search algorithm,dynamically optimizing the combination of active and passive response resources.This aims to minimize costs while meeting response reliability and grid regulation requirements.Finally,simulation analysis through case studies demonstrates that the proposed mechanism effectively enhances the reliability and economic efficiency of demand-side resource participation in grid interaction,confirming the effectiveness and adaptability of the mechanisms and methods proposed in this study.
