摘要：
The influences of photovoltaic micro-source characteristics on voltage stability of the series micro-grids (SMGs), whose inverters are connected in series, are analyzed. Firstly the system architecture of SMGs is analyzed; then a photovoltaic array model under complex environment is established and the relations between output voltage of SMGs and micro-source dc link voltages are discussed; finally the influencing mechanism of micro-source characteristics on output voltage of SMGs is analyzed in detail, and a voltage stability control strategy of SMGs based on hybrid energy storage is researched. The validity of the proposed control strategy is verified by results of simulation and experiments.
