Photovoltaic systems with local maximum power point tracking prevention and methods for operating same

摘要

A photovoltaic system (110) comprising: a plurality of solar cells (115); a photovoltaic inverter (120) that is configured to convert direct current generated by the solar cells to alternating current and to induce the solar cells to generate an output voltage based on a setpoint signal; and a maximum power point tracking (MPPT) module (122) that is configured to adjust the setpoint signal by a step size to follow a global maximum power point (MPP) on a current-voltage (I-V) curve of the photovoltaic system and, in response to detecting that the MPPT module is following a local MPP instead of the global MPP on the I-V curve, to increase the step size.
