An Impedance Reshaping Control Strategy to Enhance Adaptability to Grid for Grid-Connected Inverters

2018 China International Conference on Electricity Distribution (CICED), 2018
With the distributed generation accessing to power grid in high proportion, multi-level transformers and long-distance transmission lines lead to larger equivalent impedance at the grid side, so the grid gradually shows the weak grid characteristics. Under this condition, grid-connected inverters prone to resonance or instability.
