REAL-TIME SERIES RESISTANCE MONITORING IN PHOTOVOLTAIC SYSTEMS

摘要

A device includes at least one processor configured to determine a target irradiance value based on an operating current value of a photovoltaic (PV) device, a short-circuit current value of the PV device, and an operating irradiance value of the PV device. The at least one processor is also configured to determine an open-circuit voltage value of the PV device at the target irradiance value, determine a series resistance value of the PV device based on an operating voltage value of the PV device, the operating current value, and the open-circuit voltage value at the target irradiance value, and execute at least one programmatic action based on the series resistance value.
