General Engineering Guide chapter on virtual power plants introduces the project workflow and features, which are based on the principle of virtual power plants. TheGeneral Part of the Engineering Guide scope of this chapter applies to VPPs with specific capacity ranges for aggregated resources. The workflow includes planning and design stages. Basic provisions emphasize safe operation, openness, and regional adaptability. Information security is crucial, with principles like protecting high-security systems and having reliable equipment and software. Overall construction principles are advanced, secure, open, data-integrity ensured, scalable, and standardized. Digital and AI technologies like cloud computing, AI algorithms, digital twin, etc., are mentioned for application in VPPs.
