Abstract :
The research of control and protection in Micro grid technology is key to distributed generation(DG), such as wind power, Photovoltaic (PV) power generation, tidal power and so on. Through DC-AC converter or AC-DC-AC converter the renewable energy supply power to the loads, so the power electronics technology has a decisive role in DG and Micro grid technology based on renewable energy. In this paper, the problems of traditional Photovoltaic micro-source (PVMS) power generation is firstly listed, then the reason of maximize efficiency when a number of PV arrays in series connection with traditional two-level inverter is analyzed, a PV Micro-grid control strategy based on multi-level diode-clamped inverter will be proposed. The reliability and superiority of PVMS using in multi-level inverter will be testified on simulation.
