摘要
针对微电源协同运行特别是在微电网孤岛运行时协调运行问题,在讨论了基于双环控制的电压源逆变电源的输出阻抗与功率传输特性基础上,设计了功率控制器,并通过MATLAB/SIMULINK仿真,证明其能够在微电网孤岛及联网运行.
Micro-grid technology solves the problem of large-scale renewable energy accessing,and improve system reliability.But how micro sources operate in coordinated,especially when micro-grid operations on island mode has become the key problem of micro-grid technology.This paper discusses the double-loop control based on voltage source inverter output impedance and a power transfer characteristic based on the design of the power controller,and through the MATLAB / SIMULINK simulation to prove its ability to apply in micro-grid operates island mode and the grid mode.
