Centralized-distributed mixed novel energy power generation system and maximum power point tracking control method

Abstract

The invention discloses a centralized-distributed mixed novel energy power generation system and a maximum power point tracking control method, and belongs to the technical field of novel energy power generation. The novel energy power generation system comprises a plurality of novel energy power generation modules connected in serial in a distributed mode and a centralized converter, wherein each novel energy power generation module comprises power generation equipment and a direct current converter. The maximum power point tracking control method is that the distributed power generation modules and the centralized converter carry out maximum power point tracking on the power generation equipment at the same time, wherein the novel energy power generation modules and the centralized converter respectively carry out the maximum power point tracking on different areas of power generation module outputting characteristic curves. The control method enables the centralized converter and the power generation modules to work stably and reliably under communication-free situations, the centralized converter automatically works on the optimal direct current bus voltage point, the novel energy power generation modules simultaneously enable each power generation equipment to work on the corresponding maximum power point, and maximum power output of the system is automatically achieved.
