新能源发电串联分布式高能效变换系统
Distributed High Efficiency Renewable Power Systems With Modules in Series Connection
摘要
Abstract
The renewable power module, such as the thermoelectric generator and PV panel, features low output voltage and low power. Aiming at maximum output power, a high energy efficiency module-integrated-converter (MIC) and its control strategy for series connected distributed (SCD) renewable power system were proposed. The system structure and characteristics of the SCD renewable power system were analyzed in detail. The influence of the MIC's topologies on the renewable source and SCD power system was presented. Considering both the conversion efficiency and maximum power point tracking efficiency of the MIC, by employing a direct-connection mode, maximum output power over full output voltage range of the MIC was achieved. A high efficiency, high reliable MIC for SCD photovoltaic grid-connected power system was proposed and analyzed in detail. A SCD power system composed of 13 250W modules were built and tested. Experimental results were given to verify the analysis.关键词
