The embodiment of the invention discloses a method and system for controlling power generation of multiple solar cell panels. The method comprises the steps of detecting a maximum power point of each solar cell panel in the multiple solar cell panels which are charged in parallel to be input into a storage battery pack in the charging process; controlling each solar cell panel to output current in a maximum power point state; merging the output current in each solar cell panel in the maximum power point state into total current by adopting an integral input method; and charging the storage battery pack on the basis of the total current. According to the method and the system disclosed by the embodiment of the invention, by adopting a parallel integral input array, the problem of mutual interference of the power points caused by different elevations at the same time is effectively solved; and charging of the storage battery pack at the maximum efficiency is achieved by adopting adder coupling.
Description
technical field [0001] The invention relates to the technical field of solar energy, in particular to a method and system for controlling power generation of multiple solar panels. Background technique [0002] The solar power generation system (PV system) includes a PV array composed of solar cell modules (PV modules), and a power conditioner (PCS) that controls the action of the PV array and converts the generated DC power into the actual power form ). The maximum power that can be obtained from a PV array changes with operating environments such as temperature and sunlight. The combination of voltage and current in the operation of the PV array is called the operating point, and the operating point (maximum power point) that can obtain the maximum power generation also changes with the operating environment. Therefore, most PV systems install a maximum power point tracking mechanism (MPPT) in the PCS to control the operating point so as to track the maximum power point....
