Microgrids - Part 3-4: Technical requirements - Microgrid monitoring and control systems
IEC TS 62898-3-4:2023 provides technical requirements for the monitoring and control of microgrids. This document applies to non-isolated or isolated microgrids integrated with distributed energy resources. This document describes the specific recommendations for low-voltage (LV) and medium-voltage (MV) microgrids.
This document focuses on standardization of the architecture, functions, and…
Light and lighting — Building information modelling properties for lighting — Lighting systems
This technical specification identifies and clarifies lighting properties for digital building design and maintenance.
This document provides all the needed properties to design and to describe lighting systems. These properties are intended to be used for mapping between data providers and requesters. The mapping of the identifiers enables the exchange of luminaire and sensing device data within…
