This document provides a simplified approach to managing the connection of low voltage embedded generators only. It may be used at the discretion of the Distribution Network Service Provider (DNSP) to expedite the grid connection of small scale energy systems via inverters where favourable conditions exist.
As this guideline is based on certain simplifying assumptions, there is no guarantee that this approach will always provide the optimum solution for all situations. The recommended approach should be used with flexibility and judgement as far as good engineering practice is concerned, when applying the given assessment procedures in full or in part.
