Standards Development
This part of IEC 63409 specifies test procedures for the evaluation of performance of power control functions of power conversion equipment (PCE) for use in photovoltaic (PV) power systems with or without energy storage. This document covers testing requirements of the following functions equipped with the PCE:
Autonomous connection and disconnection Constant power control
– Active power control
– Change of maximum active power configuration
– Reactive power control (constant reactive power control, constant power factor control)Response control
– Active power response to frequency variations (frequency - watt control)
– Active power response to voltage variations (voltage - watt control)
– Reactive power response to voltage variations (voltage - var control)
– Power - reactive power / power factor control
