Comparison of some randomly selected utilities interconnection requirements and the compliance with the IEEE Std. 1547 - Interconnection guidelines

Electric Utilities permitting interconnection of generation (small and/or large) on their power systems have long had standards which any entity wishing to interconnect has to meet. Recently the growing importance of distributed generation (mostly less than 10 MVA), especially using renewable sources, has prompted the creation of IEEE Std. 1547 which sets requirements and guidelines for interconnecting a distributed resource with an electric power system. This paper will examine the requirements of the Std. IEEE 1547 and compare them with the interconnection requirements currently used by a number of randomly selected utilities.
