DANSK DSF/IEC TR 62898-4 ED1 PDF

In line with the methodology explained in IEC 62913-1, this document describes Business use cases (high-level use cases covering the main typical usage of microgrids and details some of them. As any business use cases, these use cases attempt be agnostic from any solutions or systems used for supporting the implementation of these use cases. System Use Cases linked to those Business Use Cases are listed for contextualizing the main functions to be performed for managing microgrids. For each of these, a short description and the involved system roles are listed in an intent to lay out technical requirements for a further analysis. In the current document, not all the business uses cases were covered in detail. Ultimately, the goal of the document is to provide a consistent level of detail for all business use cases. The document details the methodology retained to develop system use cases from the business use cases. This work feeds the setting up of the standardization roadmap for decentralized energy system, in the specific case of microgrids. This means that this work will be followed by 3 next steps: • Derive from these use cases some high-level objects to be standardized to ensure the implementation of standard based solution for microgrids, • Identify standards or standardisation initiatives relevant in the context of microgrids and engage in a collaboration for coordination, • Conclude on possible standardisation recommendations to SC8B or other TCs/SCs in IEC. Standardization activities could proceed with cooperation of concerned TC/SCs and SyCs, including but not limited to IEC SyC Smart Energy, SyC LVDC, TC 22, TC57, TC64, TC82, TC88, TC 95, TC 120. Some additional benefits are expected from the content of this document: • Harmonize the vocabulary related to microgrids across IEC initiatives, • Harmonize the roles and functions, • Harmonize the context of standardization for features cross cutting the IEC organisation. By nature, such document is expected to evolve in order to reflect in the closest way market needs related to microgrids usage. The proposed list of system use cases is a first version, proposed for review, the ultimate goal is to cover all use cases with the same level of depth.
