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.
