CISPR limits for the conducted disturbances of DC ports of PV-GCPCs

This paper reports standardization activities in CISPR and introduces newly developed limits and measurement method of conducted disturbances at the DC ports of Grid Connected Power Converters (GCPCs) applied to solar-photovoltaic power (PV) generating systems. First, background of standardization activities on the development of the limits and measurement method is described. Second, the two proposals on the measurement method and the two approaches for the derivation of the limits are reported. Third, the derivation of the limits based on the two approaches is shown in detail. Finally, the process of reaching an agreement in respect of the limits is reported, and the derived limits are shown.
