摘要: |
针对传统的基于单个V/f电源的主从控制策略受主控电源容量限制的缺陷,提出了一种适用于孤网运行状态的新的微电网主从控制策略,即以V/f控制的微电源为核心的多主电源控制方法,在微电网中可设置多个此类电源。该控制策略不需要通讯,可自行按照预设的裕度相互配合运行,并达到较好的自适应能力。利用Matlab/Simulink软件进行仿真验证,结果证明了提出的微电网控制策略是正确的和可行的,在并网和孤岛运行时都具有良好的运行特性,为微电网运行控制提供了有效的途径。 |

Abstract: |
According to the shortcoming of the limited capacity of the master power in the master-slave micro-grid system based on single V/f source, a new master-slave control strategy is presented for isolated power grid operation in the micro-grid. The new strategy uses multiple main power sources based on the core of micro-sources using V/f controllers, and more than one such power source can operate in the micro-grid. The new strategy can operate by itself automatically according to the default margin without telecommunication and it has the adaptive ability to large amount of power change. Matlab/Simulink software is used for simulation and verification, and the correctness and feasibility are verified by the simulation results. The microgrid has good operating characteristics in both grid-connected and islanded operation modes under the proposed strategy. The model provides an effective way for further research on micro-grid operation control. |
