| 摘 要： | 主要研究了微网运行的3种控制方法。根据功率型电源发电功率受环境影响的特点,在并网时对其采用P-Q控制;对主控型电源,在孤岛运行时对其采用V-f控制;同时对同种多个并联电源采用Droop下垂控制。综合3种方法建立一个比较理想的控制策略来实现最终的控制效果,并建立简单微网模型,在Matlab/Simulink环境下进行微网并网、孤岛状态转换、负荷切投等不同工况的仿真,验证控制策略的有效性。

| Abstract: | This paper mainly studies three control methods of microgrid operation.In the light of the character of generation power from power-type power supply which is inpacted by the environmental factor,the paper uses P-Q power control when it connects to the grid.Aiming at master-type power supply,the paper uses V-f control when it operates under the island mode.Meanwhile,the paper adopts droop control when several power sources connect each other in parallel at the same time.By combining with these three methods,the paper gives a better control strategy to achieve the ultimate control effect,establishes a simple microgrid model,and also simulates the microgrid with different conditions including conversion between grid-connection and islanding as well as load switching by using Matlab/Simulink.The results show the effectiveness of the control strategy proposed in the paper. |
