METHOD FOR DETERMINING A MAXIMUM POWER POINT OF PHOTOVOLTAIC GENERATORS

摘要

Method for determining a maximum power point (MPP) of photovoltaic generators (PV) by variation of at least one parameter of the two parameters search voltage and search current by means of a device connected downstream of photovoltaic generator, within a maximally searchable search area on a power/voltage curve, comprising the following method steps: initializing by defining a start point (4) with a start power with a start voltage and a start current (step 100), searching for the maximum power point (MPP) in at least one search direction (5, 6) by repeated variation of the search voltage or of the search current in the search area taking account of at least two limiting conditions for limiting the search area, and ending the search if one of the at least two limiting conditions for limiting the search area is met, or searching for the maximum power point (MPP) in two search directions taking account of at least one first and one second limiting condition for limiting the search area.
