| Abstract:Currently, virtual power plants (VPPs) in China are at the pilot stage, predominantly relying on invitational demand response, and have not yet to form comprehensive VPPs that can integrate multiple types of resources and actively participate in the market. To address the numerous challenges facing VPP construction and development in China, this paper first introduces the structure, implications, and interrelationships of the “energy-information-value” tri-layered network within the new power system, leading to a VPP operational architecture based on the integration of these three flows. Relevant issues are categorized according to this tri-layered network. In the energy layer, this paper reviews the current research status of resource modeling, generation-load forecasting, control technologies, and uncertainty management, while analyzing the challenges of theoretical research in practical engineering applications. In the information layer, it explores the significance of communication latency, privacy protection, and secure access technologies to VPP development. In the value layer, it examines the market structure of upper-level centralized participation and lower-level distributed collaboration, and summarizes the applications of VPPs in operation scenarios such as peer-to-peer trading, ancillary services markets, and multi-market coupling. Finally, there is a summary based on the current state of China’s electric power structure and market development, along with recommendations for VPP investment, construction, and operation. |
