摘要

为了更准确地描述微电网及其动态性能，本文建立了微电网部件和系统的状态空间模型。考虑到逆变器之间的相互作用和动态网络的有效性，提出了包含并联压控逆变器的微电网状态空间模型。微电网采用垂降控制实现微电网并联压控逆变器的功率自动共享和输出电压调节。该模型将电源、配电线路和控制系统的动态特性集成到状态空间模型中。该模型关注的是逆变器控制回路的细节，而不是开关动作。利用Matlab/Simulink仿真对微电网状态空间模型进行了验证。

State-space model of an inverter-based micro-grid

In order to describe the micro-grid and its dynamic performance more accurately, the state space models for the micro-grid components and systems have been developed in this paper. Considering about the interaction between inverters and effectiveness of dynamic networks, the state-space model of micro-grid including parallel voltage-controlled inverters has been proposed. Droop control has been adopted in micro-grid to automatically share power and regulate output voltage of parallel voltage-controlled inverters (VCIs) in micro-grids. The dynamic characteristics of the sources, distribution lines and control have been integrated in the developed state space model. The model focus on the detail of the control loops of the inverter but not the switching actions. The state-space model of micro-grid has been verified using Matlab/Simulink simulations.
