IEC Smart Grid Standardization Roadmap

Distribution network model management tools (for example Geographic Information System(GIS) and design tools) will also become important for utilities to model and manage thecomplexity of intelligent grids.A good description of the situation is given in IEC Document 57/991/DC, Roadmap for WG14:System interfaces for distribution management (SIDM).4.3.3.2 RequirementsAll functions described above require an increase in information exchange and therefore asyntactic and semantic understanding of a variety of different domains including AMI,Transmission, Market and Prosumer.Connections to Home Area Networks (HAN) is important as a means for utility companies toextend their reach beyond meters and incorporate smart thermostat, direct load controlappliances, smart appliances and in-home energy displays into utility systems, as well asenabling demand-response (DR) and energy efficiency programmes. Advanced MeteringInfrastructure (AMI) uses a smart electric meter or other energy gateway to enable continuoustwo-way communications between utilities and HAN based devices.Cyber security is a requirement as well as the incorporation of pricing information.4.3.3.3 Existing StandardsSee Communication System Operation.Effective sharing and exchange of information between the systems of various departments isusually a tortuous process for utilities.Increasing numbers of utilities are recognizing the strategic importance of A2A (Application toApplication) and B2B (Business to Business) integration. This is seen as a key enabler forimproving operational and business performance.The rapid advance of integration middleware technologies has created an urgent need forindustry standards that establish the common semantics required for interoperability inspecific industry domains.In the electricity domain, TC 57 of the IEC is undertaking the development of such standards.Within this framework, Working Group 14 (WG 14) is to identify and establish requirements forstandard interfaces of a Distribution Management Systems (DMS) based on an interfacearchitecture. This will facilitate information exchange among systems supporting planning,construction, maintenance and operation of electricity distribution networks.The standard interfaces will only cover areas within the focused domain of IEC-TC 57.They address major needs in terms of:• Data exchange between the various business processes,• Limitation of data entry effort and mistakes,• More accurate updating process of the various data,• More efficient sharing of data between processes.In addition, the standards can facilitate the harnessing of legacy applications and the re-useof information and application functionality across the business.Ed. 1.0 - 2009-12 50 /136
