BS PD IEC/TS 62898-1:2017

The purpose of BS PD IEC/TS 62898-1:2017, which is a Technical Specification, is to provideguidelines for microgrid projects planning and specification. Microgrids considered in thisdocument are alternating current (AC) electrical systems with loads and distributed energyresources (DER) at low or medium voltage level. This document does not cover direct current(DC) microgrids.Microgrids are classified into isolated microgrids and non-isolated microgrids. Isolatedmicrogrids have no electrical connection to a wider electric power system. Non-isolatedmicrogrids can act as controllable units to the electric power system and can operate in thefollowing two modes:

• grid-connected mode;
• island mode.
