Latest Patents
One of Zheren Zhang's latest patents is titled "Submodule hybrid MMC with low full-bridge ratio and DC fault processing method thereof." This invention discloses a sub-module hybrid Modular Multilevel Converter (MMC) that prevents energy from the AC side from entering a DC system during fault conditions. By creating a three-phase interphase short circuit at the AC side, the hybrid MMC reduces the number of full-bridge sub-modules required for DC fault processing. This innovation maintains the same fault processing speed as traditional high full-bridge sub-modules while minimizing the impact on the AC system. The duration of the fault does not exceed 30 ms, ensuring stability in the AC system.
Another significant patent is the "Distributed voltage clamping method for 100% renewable-energy sending-end grid." This method involves selecting key nodes within a renewable-energy grid and installing dynamic reactive power compensation devices at these nodes. These devices are controlled by an adjustable constant AC voltage effective value, allowing for real-time adjustments based on operational conditions. This approach enhances the grid's stability and efficiency, making it more adaptable to variations in renewable energy generation.
