Realizing the interconnection, interaction, and precise regulation of adjustable resources in the source network, load storage, is the key to expanding the control mode of the new power system and establishing flexible, reliable, and economical control methods. This article focuses on the demand for interactive response of adjustable resources in the source network load storage, and provides the architecture of the interactive control system for the source network load storage interconnection, as well as the integration and management of adjustable load information. A decision scheduling method for large-scale adjustable resource demand response is proposed to support the interactive response and optimization control of multiple types of resources. Finally, the effectiveness of the proposed method was verified through case analysis.
