中文摘要: 针对微电网系统中多个微源的协调问题，基于模糊算法改进的下垂控制和微电源各自的工作特性，提出了一种新型的分层控制策略，把模糊下垂控制作为主电源的控制策略，多个微源作为主电源协同维持电网的稳定：将蓄电池作为1级控制的主电源，平抑小功率的负荷波动；将容量大、输出稳定的微型燃气轮机作为2级控制的主电源，应对电网较大功率的负荷波动.最后，通过PSCAD/EMTDC仿真验证了控制策略的有效性.
Abstract:Regarding the coordination problem of micro-grid system with multiple micro sources,a new hierarchical control strategy is put forward based on fuzzy droop control as control strategy of the main power supply,and several main powers working together to maintain cooperative micro grid stability,with the battery as the main power of 1 level control,and in the face of fluctuations of small power.The micro gas turbine with large capacity and stable output is taken as the main power source 2 level control,which faces large power fluctuation.Finally,the effectiveness of the proposed control strategy is verified by PSCAD/EMTDC simulation.
