AI Technical Summary
Traditional flexible interconnection devices are expensive and occupy a large area, making them difficult to apply on a large scale. In addition, the voltage stress and rated capacity of small-capacity ports are limited, making it difficult to cope with scenarios with high phase angle differences in interconnected power grids.
By adopting heterogeneous module hybrid recombination technology, a common DC bus port is provided through the mixture of cascaded H-bridge modules and neutral point clamped converter modules, voltage level matching is achieved, the connection transformer is eliminated, and the power regulation of parallel modules and series modules is combined to adapt to the high phase angle difference of the interconnected power grid.
It reduces the cost and volume of the device, expands the power regulation range, effectively copes with the phase angle difference of high interconnected power grids, and realizes low-cost flexible interconnection.
