Title:
PHOTOVOLTAIC POWER GENERATION SYSTEM PERFORMING MAXIMUM POWER POINT TRACKING FOR EACH UNIT GROUP
Document Type and Number:
WIPO Patent Application WO/2013/094838
Kind Code:
A1
Abstract:
The present invention relates to a photovoltaic power generation system performing maximum power point tracking for each unit group which performs separate maximum power point tracking for each photovoltaic string, maximizes the inversion efficiency of an inverter by maintaining uniform input voltage from the inverter regardless of the difference between generated energy and generated voltage for each photovoltaic string, and thus improves the photovoltaic power generation efficiency. A photovoltaic power generation system performing maximum power point tracking for each unit group according to the present invention comprises: a plurality of photovoltaic strings formed by connecting a plurality of photovoltaic modules; a string optima for converting voltage generated from each of the plurality of photovoltaic strings into an output voltage of a uniform size, and controlling, for the conversion of the generated voltage, the maximum power point tracking for each photovoltaic string; and an inverter for converting the output voltage from the string optima into alternating voltage and supplying the power system therewith.
