Photovoltaic (PV) grid-connected system is the development trend of photovoltaic systems. According to the PV grid-connected system characteristics, analyzes the maximum power point tracking(MPPT) control strategy based on two-stage power conversion architecture, proposed a novel MPPT control algorithm, it can achieve the maximum power point tracking by only detect one parameter-the inverter output...
The grid-connected photovoltaic system is the trend of the photovoltaic system. On the basis of the analysis of the equal circuit about the solar cell and the character curve, for the two-stage grid-connected inverter, provide the maximum power point tracking (MPPT) methods, and design a photovoltaic inverter based on the DSP which controls the maximum power point. Trough testing the old designed...
The anti-islanding control of the PV grid-connected inverter has long been a concern of both utilities and generating equipment owners because of the potential for safety hazards and equipment damage. So the islanding effect must be prevented in the application of the grid-connected PV system .In this paper, the theory of passive and active islanding detection methods is analyzed and compared. Then,...
With the development of microelectronical technology, modern communication, network technology, network surveillance technology is continuously improved. It related to the operation and management of devices in Solar Photovoltaic system. In the system, we plan to adopt Ethernet and construct embedded Web server which is based on DSP, and transplant Iwip protocol to the Web server. The system can be...
