摘要

对于微电网系统的运行来说，出于安全稳定的考虑，当系统出现故障时，必须从电网中退电。同时，还需要保证微电网剩余设施的持续供电。为了实现这一运行任务，具有成网控制的逆变器被认为是近年来较为成熟的解决方案。本文对集成在两个储能系统中的30kVA和5kVA并网逆变器微电网系统进行了建模，并设计了虚拟阻抗下垂控制，使逆变器在离网状态下运行。利用MATLAB/Simulink进行功率共享仿真，验证所提出的微电网和并网逆变器模型的性能。

Grid-Forming Inverter Control for Power Sharing Simulation in Microgrid

For the operation of the microgrid system, it must de-energize from utility grid when the system meets fault conditions due to the safety and stability reasons. Meanwhile, it also need to guarantee continued power supply for the remaining facilities in microgrid. To achieve this operation task, inverters with grid-forming control are considered as mature solutions in recent years. In this paper, a microgrid system with a 30kVA and a 5kVA grid-forming inverters that integrated in two energy storage systems are modelling and the droop control with virtual impedances are designed for the inverters to operate in off-grid state. MATLAB/Simulink is implemented to carry out the power sharing simulation for the validation of the performance of proposed microgrid and grid-forming inverters models.
