Abstract  
A new distributed DC Bus nanogrid structure was proposed aiming at the power supply for the future smart building  and house, which mainly consisted of renewable sources, storage battery, grid connected converter and load. Considering the structure and the characteristics of modular operation and its load switched frequenly, a new DC Bus control method which based on the bus voltage control was proposed and the plug and play of each module in the grid was achieved. To suppress the resonance interference among the modules operating together, a low pass filtering section was adopted to the current feedback loop to keep the voltage stable when modules were plugged in or out. Simulation was performed on Matlab Simulink platform and the feasibility and reliability of the control method were well verified.:

模块化直流纳米电网即插即用控制策略

针对未来智能楼宇和家庭的供电需求,提出新型分布式纳米电网的组网结构,主要包含新能源发电模块、储能模块、并网模块、负载模块等.针对直流纳米电网的模块化运行、负载切换频繁的需求,提出基于直流母线电压信号的新型控制策略,实现直流纳米电网内各个模块的即插即用功能.针对多模块协同工作时产生的谐振问题,采用在电流反馈回路中增加低通滤波环节的方法保证在模块接入退出时直流母线电压的稳定.利用Matlab软件的Simulink平台搭建仿真模型并进行系统仿真,仿真结果表明所提控制策略的有效性、可靠性.
