Recommended Practice for Utility Interface of Photovoltaic (PV) Systems
|Publication Date:||30 January 2000|
This recommended practice applies to utility-interconnect
This recommended practice describes specific recommendations for "small" systems, rated at 10 kW or less, such as may be utilized on individual residences. These recommendations will provide greater standardization for these smaller systems, thereby reducing the engineering and design burden on both the PV system installer and the interconnecting utility.
"Intermediate" applications, ranging from over 10 kW up to 500 kW, follow the same general guidelines as small systems. Options to have adjustable setpoints or other custom features may be required by the interconnecting utility, depending on the impact of the PV system on the portion of the utility system to which it is interconnected.
"Large" systems, greater than 500 kW, may combine various standardized features as well as custom requirements, depending on the impact of the PV system on the portion of the utility system to which it is interconnected. A greater degree of custom engineering of the utility interface is to be expected as the size of the PV system grows in relation to utility system capacity.
