The importance of complying with power quality requirements is essential as failing to meet them is a sufficient reason for any grid operator to deny grid connection applications. However, limits specified by these requirements may differ among different grid connection codes, rendering compliance with power quality requirements somewhat site-specific. This is expected to change due to the increasing level of harmonisation of grid codes.
