摘要
The interest in the renewable energy sources to relieve the problems of greenhouse emissions has been promoted. Photovoltaic is one of the important renewable energy sources. The grid-connected photovoltaic generation system is the most important among the photovoltaic applications. High efficiency power converter, maximum power point tracking (MPPT) and islanding detection are the key technologies of the power converter interface for the grid-connected photovoltaic generation system, A novel grid-connect photovoltaic generation system with a new power converter control strategy, novel MPPT and islanding detection methods are proposed in this paper. A 5 kW prototype is developed and tested to verify the performance of the proposed grid-connected photovoltaic generation system. The experimental results show that the maximum power efficiency is 96.1 %, the MPPT can effectively track the change of the generated solar power and the islanding detection can meet the standards UL1741.
