IEEE Standards Association,a globally recognized standards setting body under the Institute of Electrical and Electronics Engineers(IEEE),has launched the IEEE 1547.4TM guide for design,operation and integration of distributed resource (DR) island systems with electric power systems.The guide is the first in-depth resource providing alternative approaches and best practices for deployment of DR island systems or micro-grids in India. Micro-grids have complex infrastructures and the connections to and from the larger grid need to be planned carefully.The IEEE 1547.4TM guide takes all these issues into account and includes best practices for setting up micro-grids.
