采用了分层结构的多Agent系统以实现微电网运行模式的平滑切换,该系统含上层协调Agent和下层执行级Agent.执行级Agent包含孤岛检测Agent、控制Agent和并网检测Agent,执行级Agent完成自身功能的同时,实时地与协调级Agent沟通协调.协调级Agent通过和大电网、执行级Agent之间的通信、协调,及时地对执行级Agent发出控制信号,使微电网能够在并网模式与孤岛模式之间平滑切换.提出了一种基于V/f控制的预同步控制方法,能够实现孤岛模式到预同步,同时实现微电网的平滑并网.“,”In this paper, the hierarchical multi-agent system is adopted to realize seamless switching of microgrid operating modes. The system contains the upper level coordination Agent and the lower executive level Agents. Executive level Agents are composed of the islanding detection Agent, control Agent and grid-connected testing Agent. While accomplishing their specified functions, executive level Agents also send signals to the coordination level Agent in real-time. By communicates with the power grid and the executive level Agents, coordination Agent can give command control signals to the executive level Agents, so the seamless switching between the grid-connected mode and the island mode of the microgrid can be obtained. In addition, a pre-synchronizing control method based on V/f control is proposed to achieve this goal.
